DocumentationTo quickly get started, see the downloads page. For problems, see the troubleshooting section; let me know if you're still stuck. Check the quick reference page for a brief rundown of mouse and keyboard controls, menu and export options, and what the files included with Mineways each do. Read this for the process I go through when exporting for 3D printing.
Normally you can just hit "OK" on the export dialog and things will work fine. Read on if you want to understand how to make your models less expensive, use different texture packs, and otherwise tailor you want to see printed out. What follows is extensive documentation about each part of the export and print process. If you don't want to wade through it all, at least search this page for the phrase "Key tip", as these bits are particularly useful.

InstallationInstallation is trivial: download and unzip (using 7-Zip or other decompressor) to some directory, like the desktop.
Uninstall: just delete the directory. If you created color schemes, there will be a few small entries in the registry, If you are fanatical and want to clean these out, search for "Mineways" in your registry editor and you'll find them.
Double-click the mineways.exe to run the program.
Opening Worlds and SchematicsThere are many ways to open a Minecraft world or schematic file in Mineways. If one doesn't work for you, try the next.
File | Open World: In the "File" menu header there is "Open World". Click (or hover) and move to the right to select your world. These are the worlds in your "%appdata%\.minecraft\saves" directory. The worlds are listed by their (not necessarily unique) given names on the left, their folder on the right, and arranged alphabetically by these folders. If you want to specify a different directory for where your world saves are located, use the "-s" option on the command line on startup; see the command line options.
If you want to export any particular block, use File | Open and select the "[Block Test World]" - this is an internally-generated "world" of blocks, with each block type listed from west to east in block ID order (for 1.12 and earlier; for 1.13 on I've assigned values greater than 255 in a somewhat sensible fashion), and with variants shown from north to south by their data values. To select a single block, find it, right-click it, then hit "[" to move the bottom level up by one, thus selecting only the block itself and not the surrounding grass.
Here's a view of a small portion of [Block Test World] exported to OBJ and rendered with Cinema 4D:
If you can't find your world in the list, you can select "Find your world..." at the bottom, which is the same as doing...
File | Open...: This option is for opening schematic files and worlds. Navigate to wherever your schematic or world is stored and select the level.dat file. On Windows, the default folder for world save files is "%appdata%\.minecraft\saves"; for Mac it's "~/Library/Application Support/minecraft/saves/". A pro tip: if you save or rename your schematic file to have the world "repeat" in it, e.g., rename "eiffel.schematic" to "eiffelRepeat.schematic", the schematic will load and be repeated across the map, with a minimum one block gap between each model. This can be useful if you want to create a single 3D print file that has multiple copies of the model. Also, for schematics, only, Control-A will select the whole schematic model. NOTE: the new schematic file format introduced by FAWE for 1.13 data is currently not supported in Mineways.
File | Import Settings: If you've previously exported a model from your world or schematic, you can select this data file (.OBJ, .WRL, or for STL export, the .TXT file generated) with Import Settings. Doing so will not only open your world, but will also set all the previous export settings you used to make this export file, including the color scheme and the terrain file chosen.
When you import a file's settings, the settings affect only the particular file type. For example, if you read in a WRL file for 3D printing, its settings will not affect OBJ rendering export (or even OBJ 3D printing export, for export settings specific to OBJ files, such as material output). This feature is backward compatible to Mineways 2.0, though features added since then will be given default values. A noticeable change in 5.01 is that the "Create composite overlay faces" is off by default; files from before 5.01 will read in but not change this option to on (which is what was used in 5.00 and earlier to export the model).
One other extremely useful type of file that Import Settings can read in is a script file. You can create script files to automatically perform all sorts of operations, including special ways of modifying blocks during export. See the scripting documentation for more information.The first image is a schematic pikachu7795240.schematic loaded via "File | Open..." In the second the schematic is renamed pikachu7795240repeat.schematic and loaded. The word "repeat" in the file name tips off Mineways to repeat the object. Also, I typed Control-A to select a single copy of the schematic.
Here is a 3x3 set of objects output and viewed with G3D:
MappingHere's basic map use:
- Press F3 to take you to your player's location.
- Scroll around by dragging with the left mouse button, WASD keys, or arrow keys.
- Zoom in on an area by the mouse scroll wheel, Page Up/Page Down keys, or Q/E keys.
- Mouse over a block and look at the bottom of the screen to see its location and ID. (Note that a coordinate like "-76" means "-75 to -76"; "4" means "4 to 5"). "Y" is the height.
- Use the slider at the top of the window to slice away all blocks above the given altitude.
- You can play Minecraft while using Mineways. In Mineways press the "r" key to load your world again, showing whatever changes you made.
- Search the menu for other options. Some quick notes on these less-descriptive options:
- The "hide obscured" option removes all blocks above the first air found in caves, making it easier to see the caves themselves. This option is turned on when first viewing the Nether.
- The "give more export memory" frees memory as possible while exporting. It is mostly meant for the 32-bit version (on Mac or Linux). This option might allow you to export a large model you normally couldn't, at the cost of a slower export.
Selecting a RegionTo create a 3D file for viewing or printing you first select a 3D box in your world. Whatever is in this box is exported. Hold down the right mouse button (or left mouse and Control key) and drag to define a selection area. Key tip: once a region is defined, you can then use the right mouse button to select an edge or corner and drag to fine-tune the rectangle. Hit the space bar to automatically adjust the depth to something reasonable, if need be. Pro users: Using the mousewheel with the Control key down changes the depth; using it with Shift down changes the visible height (this second mode can be slow, since the map is regenerated).
Once you make a selection, you may get a dialog as shown below. Mineways will detect when what you see is not what you'll get. It will ask if you want to set the depth so that everything you can see from above that you have selected will be exported.
By default, the heights used for the rectangular block are from y=63 (sea level) to y=255. The upper slider determines the visibility height, but usually you'll leave this one alone. You'll normally use it for viewing or selecting areas fully underground or in the Nether (or poking around your map to look for diamonds and other hidden treasures).
The selected export depth can be changed in a number of ways, even when no area is selected. The depth slider is the simplest way to modify this value. If you click the middle mouse button on a location, the depth is set to its height. The [ and ] keys shift the depth by one, and so are useful for tuning. The spacebar will also select a reasonable depth for your selection volume, based on visibility (water is considered invisible, so that the bottom of lakes will be solid). Holding shift while tapping the spacebar will treat water and glass as opaque, useful for 3D printing. See the full shortcut key list for more options.
Key tip: to see what you're doing, export the model and view with a viewer. I usually work by adjusting the box size and export options in Mineways, export, then viewing the file in G3D (which reloads the viewed file when you tap the "r" key) or, for .WRL files, MeshLab (unfortunately, their Alt-R reload doesn't clear out the previously-loaded file) to see the results. Open 3D Model Viewer is another free, solid viewer.
Exporting ModelsIf you want to render the model, select "Export for Rendering" from the File menu, or use Control-R, and save your file. The resulting file(s) can then be imported into a huge variety of 3D modelers and viewers, e.g., Blender. See this section for instructions for various popular modelers.
You can select "Export Model for 3D Printing", Control-P, to create a model suitable for sending to a 3D printer. Even if you don't have a 3D printer, you can still get it printed, usually for a reasonable price. See the next section for how to get going.
The big difference between rendering and printing is that 3D print models must be solid and well-formed. Currently Mineways treats all blocks as solid, full blocks: half-steps or stairs are treated as blocks, as is every other block. There is also no transparency for the materials, since printers do not currently support this type of creation. Models for rendering can, when full texturing is on, include billboard models for flowers, saplings, crops, and other elements. Note that the billboard locations are added in comments to the output .OBJ and .WRL files. In this way, a dedicated modeler could substitute his own elaborate grass, flower, or other models in place of the simple billboards Minecraft provides.
To make your model immediately viewable on the web in 3D, choose the third option "Publish to Sketchfab." Mineways directly uploads your model to the Sketchfab site and makes it displayable to everyone. It's fun and easy, honestly. Go here for detailed instructions.
The last option is "Export Schematic", which allows you to then import your model to another world by using WorldEdit or MCEdit. Note that Mineways can read any schematic file by using "File | Open...".
Mineways' schematic export option allows you to easily grab a volume of your world and turn it into a schematic file. This type of file is commonly used to share constructions among builders. Tools such as WorldEdit or MCEdit can be used to import them into other worlds, make duplicates, and many other operations. You can also upload and share these files on sites such as MCSchematics.com and Planet Minecraft. Signs will not have text, chests will lose their contents, objects such as paintings are not exported, and heads are turned into pumpkins. Currently no export options beyond the dimensions and the rotation angle affect schematic export in Mineways, and the rotation angle only partially works, mostly for full blocks that do not have any orientation. In other words, the orientation angle will rotate the model as a whole, but each individual block will not be rotated: stair steps and signs will still go the old direction, rails get "interesting," and so on. I'd avoid it... Also, 1.13 and newer elements will export as grass blocks and a warning is issued, since the standard schematic format does not support these.
Displaying with G3DOnce you have a model for rendering, you might want to preview it before importing it to 3D modeler. If you are using Wavefront OBJ files (the default) and not exporting separate tiles, I recommend the free G3D viewer (pro tip: hold the Alt key down and use WASD to move fast in G3D). This viewer now recognizes a special tag in the OBJ's material description that makes Mineways models display with the classic blocky Minecraft look. If you are export separate tiles, I suggest the Open 3D Model Viewer. If you use VRML or STL files, MeshLab is a fine free viewer for these other formats. See some other viewer options here.
Download this special version of G3D here. Unzip and run, then drop your .OBJ file on to the window to view it. Simpler yet, you can set up your Windows system to view .OBJ files with G3D when double-clicked. Just run register-G3D-viewer64-run-as-administrator.bat one time as administrator (see these instructions to learn how).
Camera controls: WASD for normal movement, ZC for up and down, QE for swivel. Hold down Shift to go more slowly, Alt to go fast. Escape to quit.
Aside from being a lovely renderer, G3D has additional features such as making a screenshot (F4) and recording a video (F6). The master G3D site is here.
Here's an example, side to side, of a lot of the blocks in Minecraft.
G3D displaying an OBJ rendering file:
Color SchemesColor schemes allows you to change the color for any block, and - extremely useful for 3D printing - remove any blocks you want from view. Key tip: you can eliminate all glass from your model by setting its alpha to 0 in a color scheme. This part of this video shows how to use color schemes to do this.
How do use a color scheme: From the menu, Add a new color scheme, then Edit it. Change the name "Color Scheme" at the top of the dialog that pops up to something useful, then select any block type to edit it. Color is given in hexadecimal color format. You can use MWSnap (old but free), FastStone Capture (new but costs $20), or other programs to find the hexadecimal (e.g., #787878) color value of any pixel on your screen. 'Alpha' says how opaque a block will appear on the screen, with 255 meaning fully opaque and 0 meaning fully transparent (invisible). Blocks with an alpha of 0 will be deleted when exporting. You can turn off export of all blocks by using the "Hide All Blocks" button. This feature allows you to create separate parts, e.g., a glass roof could be created by then turning on just glass export. The "Hide Tree Blocks" hides all log and leaf blocks, making printing of 3D terrain simpler (trees are sometimes hard to print well).
Changing the color will affect the 3D print model's color for only the "solid material colors" and "richer color textures" export modes; "full color texture patterns" (the default on the export dialog) will not be affected (except water, a little bit). To change full color textures' colors, you need to edit the input terrainExt.png itself. See TileMaker.
"My Model's Too Expensive!"If you export to 3D print and upload to Shapeways, you might be surprised to find that the price is sometimes just shy of a used car. For example, this model of our spawn area is 15 x 9.8 inches in size (about 190 x 125 blocks, 2 mm wide), and costs $633.14. Expensive models happen because either the model is too small, or too large. The problem with models with only a few blocks in them is that you'll then scale it up to see it: each block itself is then massive. You have to pay for each block's volume. Mineways can't help you much there, you'll need to use a CAD program to hollow out your object manually. Shapeways has a tutorial on hollowing.
The more common problem you can hit is the blocks are not small enough. This happens with larger models, those 100+ hour darlings you sweated over in Minecraft. The cause is that, by default, Mineways exports the model to print at a safe size. Colored sandstone has a thin wall dimension of 2 millimeters. This means if some wall in your model is less than 2 mm thick, it is in danger of breaking into pieces if printed in color.
Rule of thumb: colored sandstone has a cost of $6 for every thousand blocks printed at the default 2 mm/block. There's a fixed cost of $3 per model, and $6.50 shipping. For example, if you want to spend $50, at this scale your model can have about 6750 blocks, after subtracting the fixed costs.
There are some solutions to the price problem:
- Switch to the white and flexible physical material. Choose this material in the options dialog on export and the thin wall minimum drops to 0.7 mm. This brings the price (and size) of your model down, from about $6.00 per thousand blocks to $0.48 per thousand. You do lose color printout, but can paint the model yourself. Your model should print safely.
- Print it smaller and cross your fingers. Change "Make each block 2 mm high" to "Make each block 1 mm high", for example: at 1 mm/block, you can print 8 times as many blocks as 2 mm/block: $0.75 per thousand blocks. I like this scale a lot, it's cute. Two examples: World in a Bowl and Sentinel Castle. If you don't have any tree trunks (which at 1 mm will snap right off), thin walls, or other filigree, the model should be fine. You can remove trees from your model by using a color scheme that makes leaves and logs invisible. See this video, which shows how to make glass blocks invisible; just do the same with logs and leaves. At worst, at 1 mm other little bits might break off. Companion cubes will print with no problems, models of ships with thin masts and lanyards are much less likely to survive. Keep going smaller until you like the price, or simpler yet, just choose the scaling option "Aim for a cost of $25.00" or whatever you want. Note that Shapeways itself might refuse to print your model if they believe some parts are too thin to support the structure; here's an example where Shapeways decided the support struts were not thick enough.
- Learn more about the options below. Proper use of "fill bubbles" and "super-hollow" can easily combine to reduce your costs by 2/3rds. "Seal off entrances" and "Fill in isolated tunnels" can also help. These options are extremely useful for going to a smaller scale but still having thick enough walls. The strategy I like is to have the interior of the building get filled with blocks by using "fill bubbles" and then have "super-hollow" remove most of these blocks, leaving a shell that's thick enough to print. Long and short, don't print what you can't see.
By default, Wavefront OBJ *.obj (and *.mtl) files are exported for rendering, VRML97 (aka VRML2) for 3D printing. Here's the rundown of the various file types you can select, including some subtleties about each.
OBJ, absolute: Wavefront OBJ is an old format, so is commonly supported as an import format for a huge range of applications. If you export materials, a corresponding *.mtl file is output; if you export textures, one or more *.png files are also created. The .obj and .mtl files are text files, so can be edited or processed further. By selecting "absolute" for the OBJ file, indices are absolute (positive), the norm. This is the format to use for export for upload to Sculpteo. See other export choices in the OBJ file export options documentation.
OBJ, relative: relative indices are used on faces. These allow you to concatenate two or more OBJ files into a single OBJ file.
Binary STL: This file format is commonly used by 3D printers. It normally is used for single-color materials, but the exporter will use either the Materialise Magics or VisCAM format to attach colors to triangles - see this article. I recommend using VisCAM's variant, as MeshLab will then display the proper model colors. When STL files, binary or ASCII, are exported a corresponding *.txt file is generated with information about the model. This same data is included in the beginning of the *.obj and *.wrl files themselves. This text file can be read back into Mineways using "Import Settings" to set everything back the way it was set before.
ASCII text STL: A variant for 3D printers, the file generated is considerably larger than the binary form and cannot include color. The main advantage is that this file type is a simple text file and so can be easily edited. The format is trivial and so can provide a raw set of triangles for a model.
VRML97: Also known as VRML2 or VRML 2.0. While this format has been superseded by X3D, it is commonly supported by a wide range of packages. That said, its main reason for existence here is that it's the only file format that Shapeways uses for colored models. The *.wrl and *.png file created are put into a zip file and uploaded to Shapeways for printing - see more about this process below. The VRML file produced is tailored toward making a single texture for printing. Note: Shapeways will properly preview all VRML output modes other than "solid material colors", where it has a limit of 16 different colors. These colored models will print fine, however.

There is a bewildering dialog that pops up on export, with a ton of options. You can blithely ignore this dialog and always just click OK (or the Enter key). However, some of the options are extremely useful, so plow on if you want to make sure your model is good enough, smart enough, and gosh darn it people will like it.
World coordinates selection: you can see and change the 3D volume of space to export from your world. If you want to know the location of a place in your world, use the F3 key when playing Minecraft. Note that negative values like -5.239 will round down to -6. Also note that your Y-value altitude is one higher than where your feet are located, and so two higher than the ground beneath you.
Key tip: If you exported a model in an earlier session and want to use the same settings for another export, read the model file (.OBJ, .WRL, or for STL the .TXT file) with the "Import Settings" command from the "File" Menu.
Create a ZIP: like it says, when exporting for 3D printing a ZIP file of the exported files is created, ready for upload for 3D printing at Shapeways or other service.
Create files themselves: the exported files themselves are also made available for previewing. By default, this option is off for VRML 3D printing, on for everything else. This is done because too often the .wrl file got uploaded to Shapeways; you must upload the .zip file.
On the left of the dialog are texture options:
- "Export no materials" option is just that.
- "Solid material colors" will give solid swatches of color for each material. The color scheme's colors controls these.
- "Richer color textures" gives texture tiles that have some noise in them. For the OBJ file format the difference is that a PNG texture file is output; VRML97 always exports a texture for any material option. The color scheme's colors controls these.
- "Full color textures patterns" requires the terrainExt.png file, reading this file to create full textures for each block, as possible. The color scheme affects only the water color: the higher the alpha set, the more of the base color you define is combined with the water texture. So, for a deeper blue, you can define the two water colors (note there's a "stationary water") as dark blue or even black and a high alpha, e.g., 200.
- "Tiles for textures" can be used only when exporting Wavefront OBJ export for rendering. It is like "Full color texture patterns," except that instead of exporting the three RGB/A/RGBA textures, single images (which I call "tiles") are exported for the block faces, by default to a subdirectory "textures". These tiles are named similarly to Minecraft's block textures, though possibly modified to improve how alpha cutouts look. This mode allows you to modify and swap individual textures. Since each texture is separate, mipmapping works correctly for distant blocks. Various options are ignored in this mode, such as the various OBJ grouping and material options and the composite overlay faces checkbox. Note that the G3D viewer currently does not handle this type of exported model properly; the Open 3D Model Viewer does. Also, note that if you want to manually upload an OBJ with separate image tiles, Sketchfab has a 100 texture image upload limit. Finally, if you make a zip and do not "create files themselves," the PNG tile files will not be deleted, since they may be shared by other exports.
Content is shown on the left exported with "full color texture patterns" and on the right with "tiles for textures." Mipmapping works properly with separate image tiles.
Texture output: If you export textures, there are three types of files that can be output to PNG files, as needed. "RGB" is a colors-only file, "RGBA" is colors and transparency, "A" is just the transparency values. For 3D printing, only the RGB file is exported. For rendering export, if any blocks needing transparency are found in your model, then the "RGBA" and "A" files are also exported. Most rendering systems need only one or two of these file types, not all three. You can turn off output of any of these file types by unchecking the corresponding box.
This option can save you much time if you are exporting again and again while using a large custom terrainExt file (the next paragraph explains what this file is). You can export your model once with textures on, then modify your export and, by exporting to the same file name, you don't need to export the textures again. For the "tiles for textures" option, you need to uncheck all boxes to turn off tile creation and export - one box checked means all tiles will be output.
The one file you may want to change is the terrainExt.png file that comes with Mineways. To select a different terrainExt.png file, use the "Set Terrain File (terrainExt.png)" under the File menu. Mineways comes with a number of premade terrainExt.png files for you to try. If you have a terrainExt.png file you would always like to use by default, copy it into the directory where mineways.exe is located and call it terrainExt.png, replacing the one that is there.
To make terrainExt.png files yourself, use the TileMaker.
Here are some of the texture pack terrainExt.png files distributed with Mineways, displayed with G3D.
Click on an image for the larger version.
The effective 3D print resolution of textures appears to be around maybe 10x10 for the default output block size of 2 mm/block. Fine details are unlikely to be visible, though sometimes I'm surprised to see them.
One warning: 128x128 and larger tile texture packs will work (and will take a while to process), but previewing these files in an interactive viewer may not work. This is because DirectX and OpenGL have limitations on the maximum texture size. These texture files should display fine in offline renderers.
Internals: the tiles are each given a border 1 pixel wide. This border avoids bilinear interpolation artifacts. However, mipmapping will not work well, since tiles are next to each other, so disable it for rendering (other sampling techniques should work fine). If you cannot disable bilinear interpolation in your renderer and want a blockier look, take your terrainExt.png file and resize it to be say 4x larger in both directions - you can use the TileMaker program included with Mineways (use the "-t tileSize" option), or any other image manipulation program (I'd use "nearest neighbor", if possible - IrfanView has this option when resizing a texture by doing "Size method: Resize"). Note: from experimentation, this higher resolution does not improve the clarity of 3D texture printing.
On the left, the basic 256 x 544 terrainExt.png file is used; on the right, the input terrainExt.png image is resized (without filtering) to 1024 texels wide. You can download high-resolution versions of terrainExt.png: 1024 wide and 8192 wide.
- Export separate types: on by default, this option says each type of block - stone, logs, fences, and so on - are grouped together into objects. Turning this option off makes the whole model a single object, which can be useful for simplifying import into rendering packages. This option does not affect how many materials are generated.
- Export individual blocks: This option is mutually exclusive with the previous option, "Export separate types." Normally Mineways exports only those faces that are visible. By checking this box, every block's faces are output, allowing you to animate such operations as mining or explosions. This considerably increases file size and render time, so use it only if you need it. If you also turn on "Material per block ID family," each separate block is put into a separate object, so each can be deleted, animated, or otherwise modified in a modeler.
- Material per object: on by default; similar blocks are given the same material. If turned off and exporting separate types, a single material is used for all objects. When exporting individual blocks, this checkbox affects whether each block is in its own group (making it easy to edit) or whether individual blocks are grouped by material.
- Split by block type: Blocks have a family and a type. For example, the Stone family has stone, granite, polished granite, diorite, and so on. When checked, the individual types are used for grouping and materials. This option is off by default, because turning it on yields noticeably more materials, which can mean more editing for you. Each material is identified by its data value suffix, e.g., "Stone__5" is Andesite. If the data value is 0, no suffix is added (so the material named "Stone" is plain old stone, data value 0). New materials are limited to those where there's a physical difference in the material itself, not just geometric changes. A block being "active" or a cake being sliced will not give it a separate material and group. Crops are given separate materials for each growth level, and farmland for each wetness level. Redstone wire is given its 16 levels of power, even though Mineways itself differentiates only between off and on states.
Confused yet? There are non-obvious interactions among the various settings. Here is a table summarizing the combinations.
|Export separate types||Export individual blocks||Material per object||Split by block type||Effect on objects||Material library produced|
|SELECTED||unchecked||SELECTED||unchecked||Default for rendering: Polygons are grouped by block family||Each block family has a separate material|
|SELECTED||unchecked||SELECTED||SELECTED||Polygons are grouped by block type||Each block type has a separate material|
|SELECTED||unchecked||unchecked||unchecked||Polygons are grouped by block family||Single material|
|SELECTED||unchecked||unchecked||SELECTED||Polygons are grouped by block type||Single material|
|unchecked||unchecked||(grayed out)||(grayed out)||Default for 3D printing: No group for the whole model, just the material||Single material|

G3D material: Checking this box causes a more elaborate illumination model to be output. Specifically, the parameters Ns, Ka, map_Ka, illum, and Tf are set, and Ke is made twice as bright for any light sources (I will be removing this Ke doubling in version 5.05, as G3D no longer needs it; as it stands, the latest G3D viewer works better when not using the G3D material!). Originally this option was meant to make the (great and free) G3D previewer happy, but now G3D works about the same whether this box is checked or not.
Make Z the up direction instead of Y: some graphics applications consider the Y direction to be "up", some Z. If your model imports sideways into your application, check (or uncheck) this box.
Create composite overlay faces: For 3D printing there cannot be "floating" cutout tiles such as vines, ladders, rails, torches, and so on. These block types are overlaid atop the underlying block and a new "composite" texture is saved and used. This process must be done for 3D printing. For rendering it is an option. The advantage of leaving this option off is that the result more closely matches Minecraft itself, and that each object has its own material. It also means that all render files exported could use single set of PNG textures, since no composite textures are created. The main drawback of having this option off is that you may encounter z-fighting problems, stray shadows, or other artifacts in your renderings.
This option was on by default for rendering up to version 5.00 of Mineways (in truth, it could not be turned off); as of 5.01 this option is off by default.
Center model around the origin: when checked, the center of the bottom of the model is put at the origin, location (0,0,0). This helps for import into some renderers, and can improve the floating-point resolution of the data. If you want to instead have the same coordinate values as in your world, uncheck this box (you might also want to set the "Make each block" size to whatever you like). Unchecking this option is useful if you do multiple exports from the same world for rendering and want them to use the same coordinate space. Multiple exports are a way to get around the export size limits for the 32-bit version of Mineways, which is what runs on the Mac.
Use biome in center of export area: Instead of the default colors (seen on the Plains biome), use the grass, tree, and water colors computed by the biome in the export. Currently the biome at the center of the export is used for the whole export. I hope to export multiple biomes someday, but this is a complex export, as it can require many different color variants of grass and tree blocks. See the biomes display option for how to display the biomes.
Create block faces at the borders: this option is only available for rendering, to reduce polygon count. When on, the edges of the export the model are sealed off with whatever blocks were at the borders. For 3D printing this is necessary, as the model must be a solid object. For rendering these side and bottom polygons often are not needed, as the camera is usually positioned to never view these areas of the model. Turning this option off for rendering also allows better "tiling", where you export a world piece by piece and read all the pieces in (see center model, above), as it pays more attention to neighboring blocks just outside the borders. Note: the various 3D print "fill air bubbles" methods will turn off this method (it's a bug).
In the scene below, the camera is dollied out to see the borders. The model with borders off, on the right, has about 15% less polygons in it.
Tree leaves solid (less polygons): this option is only available for rendering, to reduce polygon count. Tree leaves are "cutout" textures, which means that by default each leaf block is exported, along with the trunks. In forested scenes this can make for a lot of extra polygons. By checking this box, leaves are made solid with a black background, which then allows many less polygons to be generated. For example, in the scene below, rendered with G3D, the transparent leaf model has 986k triangles, the solid leaf model just 369k triangles.
The rest of the options mostly have to do with 3D printing, which follows.
Exporting to 3D printAs background, view the Shapeways 3D color printing process video. Layers of material are laid down and solidified at the appropriate spots. Unsolidified "sand" is vacuumed away. You pay by volume, not by complexity. What this means to you is: avoid making enclosed spaces with tiny entrances. Unfortunately, most buildings are just that: large rooms with small doors. Your job is to make sure your model has either no openings at all, in which case the Hollow option can clear out the inside, leaving just a shell. Alternately, make escape holes yourself using snow blocks, which you then melt after all processing of your model. I'll explain these options below.
There are other potential pitfalls with 3D printing, such as thin wall problems (more here), and too many polygons (rare for a Minecraft model), to name just two. Shapeways' tutorial pages and materials pages give you a lot to chew on, Sculpteo has a good single-page rundown. The Mineways program tries to guide you past the major pitfalls, but it's always possible to generate something that's essentially unprintable: too weak, holes too small to clear out the dust, or some other problem. Browsing the tutorials there should help you understand what is possible. Options follow.
Rotate model clockwise: Can be useful for choosing a default view angle for other programs reading in the model produced. For example, the view of the model is rendered by Shapeways from the south-south-east. So if your model faces west, you might rotate it 270 degrees to have it face south and so display better on your models page.
3D printing related options: There are four major ways to scale your model.
- Make the model #N cm high: you can specify how high you would like a model to be. This is also useful for rendering output, where the default is set to be reasonable for import into Blender.
- Minimize size based on wall thickness: if you want to make "draft" 3D print models that are as small as safely possible, check this option. That said, if you know your model has thick walls, you could make your model smaller still by using the next option.
- Make each block #N mm high: by default, the safe wall size (for a non-supporting wall) is shown here. You can make this value smaller if you are convinced that your model is thick enough to print. Mineways will issue a warning nonetheless. This option is also useful for rendering output. Note for pixel-art makers: if you export pixel art, the thickness of pixel art model is usually just one block wide. Shapeways won't print a model in colored sandstone that is less than 2 mm thick, so use the "Make each block" option and set it to 2.5 mm high.
- Aim for a cost of #N: you can ask, though the wall size needed may be too small to safely print. If you get this warning on export, you'll have to decide whether the walls appear thick enough to print. This feature is imperfect: it computes a rough cost before hollowing, so that it has a sense of how small it has to make the blocks to reach the goal. Hollowing uses this size to keep the walls thick enough to print. So, sometimes the walls are thicker than needed when the model is finally exported.
Physical material: choosing a material here from among some of the Shapeways material options sets the default wall thickness and constrains the "Aim for a cost" option. It also ensures that the price is computed for that material and output in the top of the model file (or associated *.txt file, for STL output). Key tip: if you look at the export file Mineways creates for you (the .OBJ, .WRL, or for STL the .TXT file) in a text editor, at the top you'll find all sorts of useful information about the model and how you generated it.
The "White & Flexible" material has a smaller minimum wall thickness compared to "Colored Sandstone" (0.7 mm vs. 2.0 mm), so much smaller (and cheaper) models can be created in it. White & flexible is plastic and durable, colored sandstone is heavier, fairly strong, but brittle. Shapeways has a tutorial on how to paint this white plastic material, which can be fun in itself. Note that the ceramics material has a maximum wall thickness of 15 mm, something Mineways does not check; this material is also the only one where you are charged by surface area instead of volume (which Mineways does compute).
The "Custom Printer" material is used for STL export. By default, it is set to show the approximate cost of a print for 1.75 mm PLA priced at $24 for a 1 kilogram spool. The cost numbers are modifiable by using a script. See the scripting commands for "Custom printer" for how to set new cost values.
Model's units: when a model is saved, the values stored in the file are not in any particular units, like meters or inches. However, 3D printers need this scale for printing the model. Millimeters are assumed, as this is what Shapeways uses by default. For other services and printers, other units are assumed. Here's a brief rundown:
- Sculpteo - choose the "Wavefront OBJ, absolute and true" file type; by default, "Z is up" is on and the units are centimeters. Textured models are fully supported, including the truly worthwhile "Export lesser blocks" feature, though read the warnings to make sure you know what problems may occur.
- i.materialise - for this 3D print service, millimeters are the default units. For STL export, choose the "Binary Materialise Magics" STL file type; by default "Z is up" is off and the units are millimeters. Textured models are not currently supported, but colored models are, by exporting color to STL and choosing the multicolor material in their 3D print lab. If you want to import VRML for some reason, "Z is up" should be on and you'll have to change the export scale to millimeters.
- Ponoko - this 3D print service uses centimeters, millimeters, and inches. "Z is up" should be on, to show properly in Ponoko's thumbnail view. If your model is flagged as having a problem with normals, export again and check the "Weld all shared edges" checkbox. You can use the "Export solid material colors" or "no materials" options; textures are not supported. The preview itself will not show the colors, but I have been assured the model will print with color.
- RepRap - this home 3D printer appears to need models in centimeters. I'm not sure if this is more of a requirement of the related software.
By default, the model is heavily processed to clear up a number of potential 3D printing problems:
Fill air bubbles: any hollow area is filled with solid material (specifically, glass, which can sometimes be seen when doing base hollowing, below). This option can also potentially reduce the polygon count when exporting for rendering. There are two sub-options:
- Seal off entrances: If a building has 1-block wide windows and doors that are not filled in, this setting will attempt to fill these in with recessed glass blocks. This option also uses snow blocks and "entrance" blocks - doors, ladders, trapdoors, torches, fence gates, daylight sensors - to help seal off rooms, even if the doors and ladders themselves are culled. See the examples below. Sealing a room has a few advantages: the interiors of rooms that cannot be seen are filled in. This lets the hollowing option do its job better, both saving material on a print and making the print stronger.
- Fill in isolated tunnels: a volume being exported can have tunnels underground running through it, and can run into the sides of the volume itself. These tunnels cost time and money to print; if the tunnel is isolated (no access to the surface) then this option will seal these off and fill them in. Hollowing can then remove more material.
Example: in the first image, the inside of the building is not filled in. In the second, the "Seal off entrances" export box is checked. Since the model has window and door gaps that are only a block wide, these will be detected and the interior will be filled in, as shown on the right.
Wide door example: in the first image, the inside of this simple building is visible. In the second, the "Seal off entrances" export box is checked. The torches are then considered as blocking the entrance; since the entrance is fully sealed off, the room is filled with glass. This example is trivial, but by placing torches you can seal rooms off so that they fill up with glass, then get hollowed by the "hollow" option, described further on, thus saving on printing areas difficult or impossible to see from outside.
Another wide door example: Another way to seal off large doors or windows is to add snow blocks. Here a two-block-wide door will not automatically be sealed off by the "seal off entrances" option. By adding snow blocks and then also enabling the melt option, the building interior will be sealed off and then the snow blocks removed before output.
Connect parts sharing an edge: certain non-manifold edges (where two blocks are diagonal and share an edge) are eliminated by a welding process in which more blocks are added. This welding process normally occurs only when it joins pieces that otherwise would be separated and fall apart.
- Connect corner tips: if two blocks touch at just their tips and the blocks are found to be in separate parts, they are then welded together by adding two new blocks.
- Weld all shared edges: Shapeways normally allows two blocks' edges to touch, despite information to the contrary. If this behavior is unacceptable (Shapeways or some other application rejects the model), checking this box will work to remove all shared edges.
Delete floating objects: if objects hang in space, these are eliminated if they're small (less than 16 blocks in size) or are entirely tree logs and leaves. This step eliminates parts of trees hanging along the edge because of where the selection box is located. If you get a warning about there being more than one part in a model exported, crank the block number up to 1000 or more to get rid of larger chunks (once you know what those chunks are - see the debug display parts mode below). If you're sure you want just the one connected group in the scene, set this value to 999999 and only the largest object in the scene will be saved. This option can help tidy up a model for rendering or Sketchfab, too, by deleting tree foliage poking into an exported volume.
Hollow out bottom of model: models are typically resting on an uneven ground layer, and building interiors are typically filled in. Hollowing clears out blocks inside the model, making it less expensive and faster to print. The "super hollow" option is more aggressive, searching hollow areas found to see if more can be carved out.
This option, used in conjunction with seal off entrances, can make detailed models stronger. If the interior of a model is entirely filled in by the "fill air bubbles" process, it can then be hollowed out and the walls left thick. For example, say you want to print your cathedral model with 1 mm wide blocks. The printer you want to use needs walls at least 2 mm thick. Instead of manually adding blocks to the interior of your entire model, by using the seal off the entrances option you fill the interiors in with solid blocks. When you hollow, you set the hollow width to 2 mm, or even 3 mm, and now the exterior walls will be made a few blocks thick, automatically.
Technical note: superhollow can sometimes create little separate objects at the bottom layer unconnected to the rest of the model, pieces of tunnel not cleaned out. You'll need to also turn on the "fill in isolated tunnels" box to have these removed ("delete floating objects" should do this, but currently does not).
Melt snow blocks: The seal off entrances option automatically looks for one-block-wide entrances and windows and seals them off. If you have wider entrances, off-axis windows (such as in a dome), holes in the roof, or other features, instead of adding torches or ladders to help seal these off, you can use snow blocks to do so. The melt option then removes these snow blocks from your model just before output. See the seal off entrances option description for an example of its use.
Export lesser, detailed blocks: when 3D printing, this option is off by default; for rendering it is on. When not checked, smaller objects, such as signs, fences, and torches are removed - only nearly-block-sized or important blocks are exported. This option is on by default when exporting full color textures for rendering; turn it off to remove the "billboard" objects and other smaller geometry objects. Remember you can also turn off output of any block type by setting its alpha to zero in your own custom color scheme. I've given you the ability to shoot yourself in the foot for 3D printing; I leave it to you to turn off any block types you think are likely to break off. As such, if you use this option you should probably turn off the "Connect parts sharing an edge" and "Delete floating objects" options further down, as these are likely to not work well - only full blocks are tracked when using these features. When exporting lesser blocks it's better to add and delete blocks by hand and not have the program clean up the data. If you do want to check for floating objects, I recommend exporting full blocks first (which will perform the check properly if the option is checked), then export lesser blocks with the option off.
Checking this box for 3D printing is risky, but will allow you to export slabs, stairs, and many other smaller elements as true geometry. The table gives specifics about what is printable, under the "Lesser" column. The model produced with this option on can have some geometry that's tough for some 3D print slicers to process. The risk is that the service bureau or printer software cannot properly interpret your files. If you are printing a single-color model, use the free cloud version of netfabb to preprocess your model. Shapeways also uses netfabb to process your uploaded models, so you should have no problems with the mesh itself using their service. You may still have problems with features being too thin to reliably print. If you truly want to print some geometry that Mineways won't output for 3D printing, e.g., you want to make a large banner model, you can always export via rendering and perform cleanup yourself (such as removing billboards).
If you use another service bureau such as Sculpteo, look over your uploaded model for any missing block or texturing errors. Secret Sculpteo trick: you can see a large view of your model by using the URL http://www.sculpteo.com/en/embed/design/<xxx>, where you put the 8 character identifier for your model in place of <xxx>. For example, for this model the 8 characters in the URL are "hfM9BZw2", so use http://www.sculpteo.com/en/embed/design/hfM9BZw2 to see it large. Try these two links and compare.
Currently some thin objects, such as sign posts and single fence posts, are exported. These are likely to break off, especially at small block sizes. You might want to "shore up" thin features by placing blocks below them (such as for roofs made of stair steps) and next to them (such as for doors). Alternately, turn off export altogether by setting the alpha for the block type to 0 in a color scheme.
Below are three prints done with fences, stair and slab roofs, and other small blocks. On the left, 1 mm/block, the fences and thin pillars have sheared right off. 2 mm/block, in the middle, survived intact for the most part - not surprisingly, a free-standing door at the rear broke off. With 3 mm/block, on the right, a part of the fence broke off when the superglue was applied. More photos can be found here. (Image courtesy of Alex Boden)
Fatten lesser blocks: If you do decide to export using the "lesser" option, by default some of the more delicate blocks are made fatter so that they are less likely to break off during printing. No guarantees! The blocks fattened are: fences, fence gates, doors, free-standing sign posts (which I suspect will still snap off), pressure plates (since they sometimes get used for table tops), bells, and a number of others - see the table.
There are also two debug print options available, both shown in examples above. The "Debug: show floating parts" option does just that: the largest object is made semitransparent and smaller groups each given a unique color, so that you can see what pieces of the model are not connected. Either remove these smaller parts by kicking up the "delete floating objects" limit, or go into Minecraft itself and add blocks to attach them together. That said, separate parts are fine in a file if you know what you are doing: you could be making a chain of separate links, or could have a number of individual pieces (such as letters) you want to create in a single print run.
The "show weld blocks" option shows what blocks are added by the various "connect parts" options. If you don't like where the welds are put, you can go into your Minecraft world and edit the model yourself. Key tip: you can run Mineways and play Minecraft at the same time. So, you can edit your world in Minecraft, then reload the world into Mineways by pressing the "r" key. The selected area won't be cleared when you do so, so you can edit, reload, export, and view the model (in a separate viewer); lather, rinse, repeat. This is an efficient way to improve and view any model you're working on.
TileMakerTileMaker is a command-line utility for making a terrainExt.png file, which is the file that Mineways uses to add textures to surfaces. Note: currently the program works only on the PC. I have heard you can run it through WINE or some emulator (which should work but costs money).
TileMaker works by using a few different textures from Minecraft or from a resource pack to create a new texture to feed to Mineways. Specifically, here's how to set things up:
- Locate TileMaker.exe and the file terrainBase.png. The terrainBase.png has the default textures for when replacement tiles in your texture pack are not found.
- In this directory where TileMaker.exe is located, make a directory called "blocks". This is where you'll put the textures you want to use instead. Copy all files from your texture pack's assets\minecraft\textures\blocks to this directory.
- While you're at it, copy "barrier.png" to the block folder from assets\minecraft\textures\items or wherever it's located.
- Copy the "chest" folder itself at assets\minecraft\textures\entity\chest to the "blocks" folder.
- Double-click TileMaker and the file terrainExt.png should be created. Cross fingers.
TileMaker.exe and terrainBase.png blocks directory filled with files from assets\minecraft\textures\blocks and barrier.png perhaps from assets\minecraft\textures\items chest directory inside a copy of the assets\minecraft\textures\entity\chest directory
A problem with this approach is that TileMaker will run, popping up a window briefly and then disappearing. There are often warnings and sometimes errors, which you will miss. Better is to use the CMD window, go to the directory where TileMaker is located (using the "cd" command), then type "TileMaker" and see what warnings and errors you get. Any error will halt execution, at which point you'll want to fix the error and run again. You can usually use the "up arrow" key to bring up the last command you typed in, e.g., "TileMaker".
A little background might help. Minecraft itself and all resource packs have their own block image files. You'll find your Minecraft executable in a directory such as "C:\Users\YourName\AppData\Roaming\.minecraft\versions\1.10.2". If you unzip the Minecraft jar file there, e.g., 1.10.2.jar, you'll find the tiles used in the jar directory "assets\minecraft\textures\blocks". They have names such as "anvil_base.png" and "cake_side.png". These are what Minecraft uses to display blocks, and what the TileMaker utility uses to make the terrainExt.png used by Mineways.
What TileMaker does by default is simple: it reads in the terrainBase.png file, overlays it with any tiles in the "blocks" subdirectory (replacing the originals), extracts the chests from "blocks\chest", then writes out this new image as terrainExt.png. TileMaker's main task is to resize all tiles to the largest tile found. For example, if you had a bunch of 16x16 size block tiles in the "blocks" directory, along with one large 64x64 tile, the output terrainExt.png would have all its tiles be 64x64 in size. Chests' sizes are ignored during this resizing calculation.
TileMaker does do some special processing. The "chest" subdirectory normally has three chest tiles: ender.png, normal.png, and normal_double.png, to generate chest tiles - see the _readme.txt file there. The main directory has some "guide" tiles that are not standard Minecraft tiles. These have the prefix "MW_" and are mostly self-explanatory (or search this page for more information).
If you use the command line, there are many options available for doing more elaborate operations (such as forcing a particular tile size, or using a different input directory or output file name), but then you need to run TileMaker from the command line or in a .bat file. In the command line you use "cd" to go to the directory where the TileMaker.exe file is located, then do something along these lines:
TileMaker -d blocks_doku -o terrainExtDoku.pngThe "-d directory" option tells TileMaker to use this directory instead of "blocks" for the images you want to overlay. The "-o filename" tells it to write the resulting image to the filename given. Directory and image names cannot have spaces in them.
Here is a rundown of the other TileMaker options and their uses. To get a reminder of these, type:
TileMaker -?on the command line.
TileMaker [-i terrainBase.png] [-d blocks] [-o terrainExt.png] [-t tileSize] [-c chosenTile] [-nb] [-nt] [-r] [-m] [-a] [-v]
-i terrainBase.png - image containing the base set of terrain blocks (includes special chest tiles). Default is 'terrainBase.png'.
-d blocks - directory of block textures to overlay on top of the base. Default directory is 'blocks'.
-o terrainExt.png - the resulting terrain image, used by Mineways. Default is terrainExt.png.
-t tileSize - force a power of 2 tile size for the resulting terrainExt.png file, e.g., 32, 128. Useful for zooming or making a 'draft quality' terrainExt.png - a low-resolution terrainExt.png makes for a much faster export. If not set, the largest tile found in the base or blocks directory is used.
-c chosenTile - for tiles with multiple versions (e.g., water, lava, portal), choose which tile to use. 0 means topmost, 1 second from top, 2 third from top, and so on; -1 bottommost, -2 next to bottom.
-nb - no base; the base texture terrainBase.png is not read. This option is good for seeing what images are in the blocks directory, as these are what get put into terrainExt.png. This terrainExt.png file is probably not usable as is, since terrainBase.png contains some special tiles, such as those for the chests.
-nt - no tile directory; don't read in any images in the "blocks" directory, only the base image is read (and probably zoomed, otherwise this option is pointless).
-r - replace (from the 'blocks' directory) only those tiles not in the base texture. This is a way of extending a base texture to new versions of Minecraft, while retaining existing blocks. For example, say you spend some time making a great terrainExt.png file you love. A new version of Minecraft comes out, adding say a wheat mill block. You put this new wheat mill block image in the blocks directory, get the latest version of Mineways/TileMaker (which hopefully would support the wheat mill), and run with "-r". This reads the blocks directory and checks the terrainBase.png at the same time. If terrainBase.png has no data for the tile's location, i.e., it's black with an alpha of 0, then the block is used to create a terrainExt.png file, otherwise the block is ignored.
-m - to report all missing tiles, ones that Mineways uses but were not in the tiles directory. This option is a way of finding if there are any images you can still add to the "blocks" directory. For example, if "nether_brick.png" is reported missing, you know that "blocks" doesn't have this image and that Mineways will use it. This merely means that the default terrainBase.png texture will be used instead.
-a - include alternate texture names when files are not found. These alternate names can be found in tiles.h, alternate names of textures sometimes found in block texture directories.
-s - output solid color. Instead of exporting the texture, export a solid color formed from the average color of the texture. This is useful if you want specific colors for block faces or for various IDs for a block type. The texture produced is more appropriate for 3D printing.
-S - output solid color with cutouts. As above, but for rendering. Note that the "grass_side_overlay" texture will still affect the side of the block, so modify this texture to avoid detailed grass block sides.
-v - verbose, explain everything going on. Default: display only warnings.
There are lots of cool add-on shaders for Minecraft. But, for truly stunning stills and animations you'll want a standalone package. This section covers the basics on importing Mineways files into various renderers: Blender, 3DS MAX, Maya, and Cinema 4D. If you want better geometry for some blocks, you should consider using jmc2obj (though personally I have problems getting it to work properly).
To quickly check results before printing or importing into a rendering program, consider using an interactive previewer. MeshLab is a good previewer models in any format Mineways produces.
For rendering preview I recommend the G3D when using full color textures. It does not have cross-sectioning and supports only OBJ files, but has much better transparency support and shadows, and has screenshot and video capture built in.
What follows are steps for using various popular rendering software packages. There are always more; for example, this article talks in depth about using RenderMan for rendering.
Here's a quick beginner tutorial from Alexander Boden, along with ideas by Milenco Mulder and others; if you have anything to add, let me know. This is for Blender version 2.75a but should mostly work on newer versions. You'll also want to consider using MCprep in conjunction with Mineways to improve your materials, geometry, etc. Alternative Minecraft exporters for Blender include jmc2obj, a general-purpose and full-featured exporter (which I can't figure out any more), and Mineblend, which is dated, but is tailored specifically for Minecraft to Blender import.
There is some additional (dated) information on Blender and Mineways in this and this thread. There are a number of other add-ons for Blender with Minecraft, e.g., these rigs, which can give you models that Mineways itself currently does not export.
1) Open your World in Mineways, then, select the area for exporting (hold right mouse button and drag the rectangle).
2) Choose "File | Export Model for Rendering" and save the file as a Wavefront Object (.obj) to a folder of your choice. Let's call it myobject.obj or whatever you like. You could simply click "OK" in the dialog with the export settings. However, choosing the "Export tiles for textures" on the left can give better filtering results, especially for areas in the distance with large scenes, as mipmapping will be more effective.
3) Open Blender 2.75a (or later) and click anywhere on the screen to make the splash screen disappear. Then press "x" (or "delete"), and then "Enter". This deletes the default cube on the screen.
4) Import the model: select "File | Import | Wavefront (.obj)" from the menu. Search and select for your Mineways export file (the .obj file) and click "Import OBJ" (or just double-click the file name itself). Wait a bit.
If you cannot select Wavefront from the Import dialog, you have to activate this file format first from the settings menu. Select "File | User Preferences", activate the "Addons" tab, and scroll down in the list until you find "Import-Export: Wavefront OBJ format)". Just activate the checkbox at this entry, dismiss the settings dialog and try importing again.
5) Turn on textured display: near the bottom of the viewport, above the animation timeline, is "View Select Add Object" and so on. Just to the right of "Object Mode" is a shaded white sphere. Click on it and pick "Texture". You should now see the model as textured.
6) Resizing: The model we have just imported is probably small on the screen. There are two solutions: one is to use the mouse scroll wheel to zoom in and out - this changes the camera's location. Alternatively, move the cursor to the center of the screen, hit "s", and move the mouse until you have the right size, then click the left mouse button to save the size. This second method changes the size of the model itself, which you might not want to do.
7) Rendering: You are now ready to do a first render of your model. Just press "F12" or select "Render | Render Image" from the menu and have a look.
8) Material Conversion:Material Conversion: You may wish to make better materials for your objects. The easy routes are to either use one of two scripts provided with the Mineways distribution: CyclesMineways.py, or possibly blender_mineways.py, created by Nicky and improved by Wyatt Jameson. The third easy choice is MCprep, a Blender python script that can improve model quality of Mineways and jmc2obj exports.
Cycles is a high-quality renderer for Blender. To use Cycles instead of Blender's default renderer, simply click on "Blender Render" in the middle of the top edge of the application and choose "Cycles Render". (Note: if you are using Blender 2.80, see the small fix here that is needed for CyclesMineway.py to work.)
To use the CyclesMineways.py script, first download the latest version. Edit this script in a text editor. You need to add just one word, the PREFIX value listed in the CONSTANTS section, around line 45. Put whatever your save file name is. For example, if your export file is castle.obj, then change the line to this:
PREFIX="castle"Save the file.
At this point you then do exactly the same procedure as described for blender_mineways.py above, but loading this CyclesMineways.py script instead. Hit F12 to see the result.
Note: this script is in development, so please do contribute your ideas and make it better!
blender_mineways.py method: (or see videos by Nicky or Wyatt).
Just to the right of the "Help" menu in the upper left, click on the "keys" icon next to the word "Default" and pick "Scripting".
At the bottom of the gray window you'll see a menu "Text"; click it and select "Open Text Block". Go to the directory where "blender_mineways.py" is and select it (double-click). You should now see some text in the gray window. Click the "keys" icon again and select "Default" to close the scripting window.
To apply this script, click on the "Run Script" button at the bottom right of the text window.
If you want to see that the script did something, from the upper left select "Window" and "Toggle System Console". If you don't have a "Window" menu item between "Render" and "Help", you have an older version of Blender and should consider updating. This menu item pops up a console window showing what the script did. It isn't critical to see this window, but gives you a warm and fuzzy feeling that the script has worked. Hit F12 to see the result.
If either script is not working for you or you'd rather do a lot of work by hand, what follows are the step-by-step instructions for setting each material manually.
Fixing transparency: Flowers, torches, iron bars, and other blocks with cutout areas will look bad around their fringes. Look in the upper right at the Scene tree area. Select the first mesh in the list, then pick the Textures icon from the list below, then pick the "Show Material Textures" icon from the set of three icons below that:
If only a Kd texture is listed, go to the next mesh in the Scene tree at the top (by clicking on it). If there is also a D texture (outlined in green above), uncheck the box for this texture.
Then click on the texture just above the "D" texture, it starts with "Kd". Once selected, scroll down to the "Influence" section and open it up. Under "Diffuse:" check the "Alpha: 1.000" box to enable it.
Now cutouts should display correctly when rendered (but will still look bad in the interactive scene). You will need to do this for every mesh, unless you exported just one material as I suggested at the start, in which case you're done!
Fixing shadows: Now for every mesh select the Material icon (to the left of the Textures icon), and under "Shadow" at the bottom you need to click "receive transparent". Again, if you exported just one material, editing one mesh will change this material for all meshes. Conversely, for flowers and other billboards you might wish to set these to not cast shadows, or perhaps not to receive them, to avoid self-shadowing artifacts. It's tricky.
Blocky textures: If you want the blocky look for textures, select the mesh, select the Texture icon, and under "Image Sampling" uncheck the "Interpolation" box. Just below the "Interpolation" box you'll see a number of filter types, "EWA" by default. Select "Box". As usual, you'll need to do this for every texture. (Hats off to Richard Remmelink for figuring this out.) You may also find that turning off MIP Map", above "Interpolation", can help avoid line artifacts between distant grass blocks. However, mipmapping is useful to avoid crawlies during animation.
Water: this often looks a little weak by default, you can make it better (you'll need to have a separate material for the water). Select the water by right-clicking on it in the scene. This from Milenco Mulder:
Select the Material icon:
Transparency: Fresnel = 2, Blend = 1.25 (the default)
Optional is to select "Raytrace" and IOR = 1.33, though ray tracing appears to sometimes create artifacts
Mirror: check this checkbox, then Fresnel = 2, Blend = 1.25 (the default), Gloss = 0.96
Select the Texture icon:
Influence: Color = 0.8, alpha = 1.0 (the default), select checkbox Mirror = 0.3, select checkbox Normal = 0.05
At the bottom of the Influence section there's a list under Bump Mapping of Metho [sic], choose "Best Quality".
9) Camera: Go back to the interactive view by hitting "F11". Move your view around with the middle mouse button. You can rotate by dragging with middle-mouse, or hold down shift and you'll pan, or hold down control and you'll dolly. Once you like the view, click Control-Alt-Numpad 0 to set the camera to your view. If you always want your current view to show what is rendered, while in interactive mode select "View" (in the lower left), "Properties", and under the View area select "Lock Camera to View". If you found the right angle and perspective for your camera, you can fine tune a couple of parameters in the camera menu. This can be found by first selecting the Camera object from the list of objects in the upper right, then clicking the small film-camera (not the photo camera) symbol just below the list of objects, toward the right. When you click it, a section called "lens" should appear. You can set the "Shift" of the X and Y axis, as well as the focal length of the camera.
If you are happy with your results, you can select "Image | Save as Image" from the menu near the left bottom of the screen, or hit F3.
10) Ambient lighting: To achieve a more even lighting of your scene, select the "world" icon in the menu bar where you also found the camera and the lamp settings (i.e., just below the object list). Turn on the "Ambient Occlusion" checkbox in the parameter list below. Play with the "Factor" value in this section, I like something between 0.25-0.5. In this menu, you can also set the background of your scene in the "World" section. Pick the "Real Sky" option and set horizon and zenith colors as you wish.
11) Lighting: There is one predefined light source on the working area (which looks like a dot with two enclosing dotted circles). You'll usually have to zoom out to see it. You can right click to select it, or select the Lamp from the object list. Move it around the screen by selecting the red, green, and blue arrows and dragging. Then, select the Lamp settings in the same menu bar where you found the camera symbol. It looks like a small sun with four arrows pointing away from it in different directions. Click it, and you can find all kinds of parameters that affect the lighting of your scene. For example, try exchanging the "Point" type for "Sun", and play with the "Energy" value. You can also change the color by clicking the color field above the Energy settings. You can add Lamps from the "Add" menu in the upper left.
12) Render Size: You can also set several parameters of the Renderer by selecting the small photo camera icon in the menu bar where you also found the film camera, the lamp, and other choices. In the section "Dimensions", you can set the Resolution of the image, add a border, and so on. To export Full HD, you can set the Resolution to X:1920 and Y:1080, and set 100% in the bar below these settings.
13) Upload your creation to the Mineways Flickr group! (Optional, but extremely recommended)
Here's a typical result, made in a few minutes:
These instructions are for 3DS MAX 2012. You might also try jmc2obj instead, as it does a better job producing some geometry. The steps here should also work for cleaning up jmc2obj OBJ models.
For newbies (like me): in a Viewport, middle-mouse button changes the view: mouse-wheel to zoom, button to pan, Alt key down to rotate, Control key down to fast-pan. Shift+Q to render. Steps are as follows:
Step 1: Get your world and region selected in Mineways, then select 'Export Model for 3D Rendering'.
Step 2: Save as the file type 'OBJ'. You may wish to try the "G3D full material" option, as this gives a slightly different water color by changing the diffuse color to white.
Step 3: Adjust the export options as you wish. Nothing is required here; by default, blocks will come in at a size of 1/10th meter each. You can adjust this by changing "Make each block 100 mm high"; for example, 1000 mm is 1 meter, MAX's unit size.
Step 4: Use the upper left MAX symbol menu and select Import. Find the .obj file and select it. In the OBJ Import Options, under Normals select Faceted to get Minecraft's blocky look. Alternately, if you want to smooth water surfaces a bit, select "Auto" and leave the setting at 30 degrees. Click "Import" at the bottom.
Step 5: Go to Render Setup in the Rendering menu (or just hit "F10"). Select the Renderer tab and uncheck the "Filter Maps" checkbox under Antialiasing. This makes cutout objects look correct, as well as making the Minecraft textures have their distinctive blocky appearance.
Step 6 (optional): At this point rendering should work fine. In interactive preview mode you will see some transparency problems in the Viewport. To fix these, bring up the material editor by pressing "M" and expand the view. Scroll down in the Material/Map Browser on the left and find "+ Scene Materials". Click on the "+" to show the scene's materials. Double-click on whatever material looks bad, e.g., Stationary_Water, Glass, Leaves, Torch, Tall_Grass, Sugar_Cane, Rose, Dandelion, or other cutout object. Now click on the "checkerboard-with-light" icon along the top, which does "Show Shaded Material in Viewport". This material should now look better. Do this for each material that looks bad. Press "M" again when finished, to dismiss the material browser. If someone knows a faster way to change all materials, let me know. Note that these fixes do not affect the final render itself.
Check out this video from this playlist, it shows how to set transparency and texture sampling. That said, you may want to use jmc2obj, which even comes with a MEL script to perform cleanup during import.
A problem with jmc2obj is that each material must be adjusted by hand. One option in Mineways that can speed import conversion is to uncheck the "Material per object" checkbox in the OBJ file export options. Doing so means you have to fix up only one material, though at the expense of not having a separate material per object (that said, you can always add new materials later). That said, this option tends to mess up Maya's display, as every object will be considered semitransparent and all will be sorted from back to front by depth in the interactive viewport, causing objects to flicker in front of each other. The scene will render just fine, however.
Here is how to import a model and set the textures for Cinema 4D. The steps are from this excellent video from this forum post, which includes a number of other useful Cinema 4D animation tutorials and resource links. Here's one more useful post. The instructions have been updated for Cinema 4D R18; older versions may need additional steps, as shown.
That said, you may want to use jmc2obj, another exporter. The main downside of jmc2obj is that you have to reattach every single texture it generates by hand; Mineways uses just one texture, so the cleanup process is much faster.
Step 1: Get your world and region selected in Mineways, then select 'Export Model for 3D Rendering'.
Step 2: Save as the file type 'OBJ'. Use Absolute OBJ, not relative, as older versions of Cinema 4D do not read relative OBJs well.
Step 3: Adjust the export options as you wish. Nothing is required here; by default, blocks will come in at a size of 1/10th meter each. You can adjust this by changing "Make each block 100 mm high"; for example, 1000 mm is 1 meter. You may also wish to use the "Export tiles for textures" option, as this allows mipmapping and similar filtering in Cinema 4D to work better.
You may want to change the OBJ file export options in the upper right of the Mineways dialog, but the defaults are fine.
Step 4: Once the model is exported, open Cinema4D and drag into the main window the .obj file generated. Make sure the "Presets" at the top of the OBJ Import dialog is set to Default. (If you don't, your grass blocks will import upside-down.) Hit "OK".
Here is what the defaults are, just in case:
To move around the scene, hold down Alt and use the three mouse buttons and scroll wheel.
Step 5: Select all the materials in the material viewer, the row of spheres at the lower left. Do this by clicking one sphere and then hitting Control-A. All spheres should now be selected.
Step 6: In the material options area, in the right lower window, select the "Basic" box in the upper left. In the "Basic Properties" below uncheck the Reflectance option and check the Alpha option. Billboards such as grass and flowers should now look better.
Step 7: If you want to make textures look blocky, like they do in Minecraft, first click on the "Color" box next to the "Basic" box at the top of the material editor. In this area you will see a section below labeled "Color." In this section you will see "Color," "Brightness," "Texture," and just below that and to the right, "Sampling," which will say "<<Multi." In the menu list for this option choose "None." When you are done selecting, it will still say "<<Multi", but don't worry, you have changed it. See the figure below.
Step 8: Cutout objects such as flowers will still look fuzzy along the fringes. Now click on the "Alpha" box next to "Basic" and "Color." Again go down to "Texture" and under sampling choose "None." For a quick render to see the effect, click Ctrl-R.
You're now done. Note that there's a trade-off with Cinema 4D: you can't both have the blocky look and have better filtering (such as mipmapping) when you export to a single texture. You can get both effects by using Mineways' "Export tiles for textures" option.
Alternate method: VRML: If you have problems with OBJ import, or would prefer a single material for the whole scene, you can also import using VRML. Here are steps from James Christien (icecruiser xD; example C4D result here), with help from Huskyiee on alpha.
Step 1: Get your world and region selected in Mineways, then select 'Export Model for 3D Rendering'.
Step 2: Save as the file type 'VRML'.
Step 3: Adjust the export options as you wish. Nothing is required here; by default, blocks will come in at a size of 1/10th meter each. You can adjust this by changing "Make each block 100 mm high"; for example, 1000 mm is 1 meter.
Step 4: Once the model is exported, open Cinema4D and drag into the main window the .WRL file generated. Hit "OK" for the import options dialog.
Step 5: Once it is all loaded, if black ugly things are present on tiles - such as glass or torches - then double-click the material (the round sphere) in the materials viewer at the left bottom.
Step 6: On the material options, in the right lower window, select the "Basic" button. In the Basic Properties uncheck the Reflectance (in older versions, "Specular") and check the Alpha option. You should see to the right of the "Basic" button the button "Color", then "Alpha". Click on Alpha.
Step 7: In the Alpha settings, at the bottom is the Texture setting. Click on the little right arrow next to "Texture", go down the menu and select Bitmaps, and choose the corresponding PNG for the model. All the black things should now be gone, ready to be rendered properly.
Step 8: If you want to make textures look blocky, like they do in Minecraft, in the Alpha settings under Texture type from Sampling "MIP" to Sampling "none". Click on the "Color" button and change the Texture Sampling from "MIP" to "none" here, too. Note that in the interactive mode the textures will not look quite right, but when rendered are fine. For a quick render to see the effect, click Ctrl-R.
Publish to Sketchfab
Sketchfab is a free service that lets you upload your models and share them with others; try an example here or look at the end of these instructions. Mineways exports to it in a straightforward fashion, there are just a few steps to get your model up and running. It's always been possible to upload models to Sketchfab, see these illustrated instructions. With the 4.16 version of Mineways you can now publish directly from Mineways to Sketchfab. Note: you can always export a rendering as usual to an OBJ file and upload the ZIP of the files output to Sketchfab. This will give a somewhat different rendering style, sharp and less shadowed.
1) Sign up for an account on Sketchfab.
2) Open your World in Mineways, then, select the area for exporting (hold right mouse button and drag the rectangle), and choose "File | Publish to Sketchfab" from the menu.
3) The Sketchfab dialog will come up. Click on the button "Get your token." This will open a web page.
One line says "API Token," as shown below. Copy the API token, a long string of letters and numbers (a black box covers mine here), and paste it into the Sketchfab dialog. Fill in the other fields as you wish, then click "Upload" at the bottom.
4) When done, a new dialog comes up saying, "Your model has been uploaded. Click OK to view it on Sketchfab." - do that!
5) On the model's web page, adjust and save the view. You can orbit, pan, and zoom (mouse wheel). In the lower right corner is an eye icon, where you can switch to a "First Person" mode - I find it a bit zippy by default, so use the mouse wheel to dial down the speed. Also, if you double-click with the middle-mouse button on your object, you set the pivot point that the camera orbits around. Pick a nice view and then click "SAVE VIEW" in the upper left-hand corner.
6) In the lower right of the window click "SETTINGS" and choose "3D settings". I recommend clicking on the light-bulb icon in the upper left, then turn on the lights (just below); this will give shadows. There are lots of options here - explore and have fun! You can change the surrounding environment, make various materials look different, and other options. Annotations are nice for setting up views and touring your model.
7) In the upper right click "SAVE SETTINGS".. Then click "EXIT" and you're done.If for some reason you can't get the "Publish to Sketchfab" feature to work for you, or you want to use anything but the default export options, there's another way to upload to Sketchfab that's only a little more work. Follow these instructions or go through the step-by-step below.
1) Open your World in Mineways, then, select the area for exporting (hold right mouse button and drag the rectangle), and choose "File | Export Model for Rendering" from the menu.
2) "File | Export Model for Rendering" and save the file as a Wavefront Object (.obj) to a folder of your choice. Let's call it myobject.obj or whatever you like. In the dialog with the export settings click on the option in the upper left click on "Create a ZIP file containing all export model files". Click "OK".
3) Sign up for an account on Sketchfab if you haven't already, then upload the zip file you created by clicking on the "UPLOAD" button in the upper right. A dialog pops up; click on "CHOOSE FILE" and upload the .obj.zip file you created. Click "CONTINUE".
4) Fill out the form as you wish. It's nice to add "minecraft" and "mineways" tags, so others can find your model. It's also nice to "Allow download", if you like.
At this point the steps are much the same as above, starting at step #5. The main difference is that your uploaded model is not published by default; for the last step you'll want to click "SAVE AND PUBLISH," then "EXIT."
One other thing you may wish to do is material cleanup. On the Sketchfab Materials tab (the center one) is the "Faces Rendering" option at the bottom. You may notice some "z-fighting" for objects such as sunflowers, where the two textures on each side of the flower fight each other. Choose a material at the top and select "Single sided" for that material. This will make the object look better.
An irregularity: if you download your uploaded model from Sketchfab, it may not display correctly. The short version is that you probably have to comment out the "map_d" field in the .mtl file for the model. Some viewers incorrectly grab the red channel instead of the alpha channel from the four-channel map that Sketchfab uses for compactness.Here's an example of Sketchfab in action, a model I uploaded. Click on the window and you can interact with it. More models here and here.
3D Print ServicesIf you want to make a 3D print of a model, the easiest way is to use a 3D print service such as Shapeways or Sculpteo. The main differences are cost, quality, and speed of delivery. Shapeways is almost always less expensive, Sculpteo offers faster delivery and better supports the "Export lesser blocks" option, which lets you print out slabs, steps, fences, and other smaller bits in your model. 3D Hubs also has some users with full-color printers, so may be both competitive and fast. There are other 3D print services for consumers, such as i.materialise and Ponoko, but currently these two do not offer fully-textured 3D printing, just solid color blocks. There are many services offering single-color (i.e., single material, such as plastic) prints, such as any of the above or those on this list.
After creating an account (and creating a shop), go to the upload page. Choose a file for upload - you must pick the .ZIP file for your model that you created with Mineways, using 3D print export, e.g., "mymodel.wrl.zip". You also don't need to change the Unit of Measure: "millimeters" is the default and is what Mineways always outputs. Push the upload button.
Once you've uploaded, you will be taken to the model's page. Here you can preview the model in the window to make sure it looks correct. You can also order from this page by choosing the material. For a full color print you want to find "Natural (or Glossy, or Matte) Full Color Sandstone." If the material is not selectable, there may be a problem with your model. Select "Tools" near the top, just under "Bring your product to life" and choose "Open in 3D tools." You can now select the material you want and the page will show you exactly what test is failing, such as wall thickness or bounding box (model size).
Note there's a fixed cost per order. Be careful, however: you normally cannot cancel your order once placed. After you've made an order, the waiting begins, sometimes 2-3 weeks.
If you later want to make your product for sale or otherwise modify it, go to My 3D Models. Click on the three dots to the right of a model a choose the option "Edit Product."
See my humble shop as an example of how I set up various models.
Go to the Sculpteo site and register for an account.
In Mineways, you normally want to export to Wavefront OBJ when exporting to print, using the "Sculpteo" file type. Sculpteo also accepts VRML2 files, but the OBJ exporter sets some useful defaults for Sculpteo, such as centimeters for model units. One major advantage of Sculpteo is that they support the "Export lesser blocks" option, which allows you to export slabs, stairs, fences, doors, and other smaller objects. Please read the documentation for that option before using it. Also note that when you export, the price shown is the Shapeways price; Sculpteo prices tend to be about a third higher overall.
You should then get a page showing your model has been uploaded. You can interact with it in the viewport using left-mouse, right-mouse, middle-mouse, and scroll wheel. Pro tip: note that rotating by going up and down near the edge of the window gives a different rotation than going up and down in the middle. This can help you adjust the "up" direction.
You now have a number of options. The "Click to see repair work on your model" shows where objects were merged - usually not that useful. "See the price" brings you to the main page for the model. From here you can do a wide range of operations, and they're mostly self-explanatory. You can choose the material (colored by default), change the overall scale (and see the new price), or perform a solidity check. This last option is useful for seeing if some part of your model is likely to snap off during printing.
Note the links above these options. "Settings" lets you add photos, change your description and sharing options, and set the initial scale for the object. "Customize" gives some worthwhile options, such as engraving text, adding images and symbols, and smoothing the design. This last option can give a different sort of look to smaller models, though there is a risk of some bits of the model becoming detached when printed.
ScriptingBy using "Import Settings" you can make Mineways do all sorts of things quickly. You can also temporarily modify blocks when exporting. It's easier to use than you might think, read about it here.
Related ResourcesHere are some related (free) tools that are handy, collected in one spot:
- MeshLab for viewing exported models for 3D printing.
- The G3D viewer is excellent for previewing 3D OBJ files for rendering (sorry, not VRML or STL), as its support for cutouts is superior to the MeshLab viewer. It also includes real-time shadows and reflection-mapped water, as well as built-in screen and movie capture (only the viewer32.exe version has video capture). Models also load faster. Downside: on weaker GPUs it can be slow, and it doesn't work when exporting separate texture tiles. Some examples here.
- The Open 3D Model Viewer is good overall for OBJs and many other file formats. The main drawbacks are that semitransparent objects (e.g., water) are not properly blended atop the rest, and that the camera cannot be locked to have +Y be the "up" direction. But, it handles separate texture tiles properly.
- The VisCAM View is good for viewing and checking STL files.
- MeshLab helps you convert, simplify, and smooth meshes, among a huge number of other operations. It's not the best for displaying textures.
- MCEdit Unified lets you make large-scale changes on your world; documentation here. For example, you could trim away objects near your model to make a cleaner export. You can also read in model schematic files from sites such as this. To use a schematic with Mineways, import the schematic into an empty world and save the world, then use Mineways on that world.
- WorldEdit is another mod that lets you make large edits to your world. It can load and save .schematic files, allowing you to export a model from Mineways and move it to a separate world. It also allows a huge number of modeling operations, including procedurally-generated models. It differs from MCEdit in that it is a plug-in to Minecraft, while MCEdit is standalone.
- VoxelSniper is another Bukkit addon for servers, providing a wide range of editing abilities.
- Mine-imator is a self-contained Minecraft video animation system. It can read in and view schematic files, among much else. Direct download.
- Spritecraft converts an image to a schematic file, allowing you to easily create pixel art.
- Binvox goes the other direction, letting you turn a model file into a voxelized representation, suitable for building or export to a schematic file. I have a quick-start Binvox package for Windows: binvox, viewvox, GLUT DLL, two sample 3D models, and batch files to run the programs. Documentation here. For more info, see the forum thread and related forum thread, and album. I used it to make the teapot, guardian, and hopper, among other models.
- Qubicle costs money, but has some nice functions. It is a set of voxel-based utilities, including an editor and a voxelizer that computes a good color for the voxel from the material.
- CraftMaster has developed a program for voxelization specifically aimed at Minecraft, and that exports directly to Sketchfab.
- TinkerCAD is an online CAD program. You can now export to Minecraft from it - try the "Download for Minecraft" feature, now with materials. You can also search for Minecraft-related objects. See this video for how to use it and export.
- Biome Painter lets you modify the biomes of your world. If you get it, make sure to use the "Help" menu "Check for updates" feature.
- Eihort is a fantastic 3D viewer for your world. You can zoom through, see a huge distance, and get coordinates for wherever you are. It's slightly outdated and buggy right now, but a new version is in the works.

Stuff to PrintWant something to try Mineways on? There are a number of sites with cool downloadable models and worlds, including:
- Planet Minecraft projects - all sorts of great stuff to print, sorted by popularity.
- Minecraft World Map has a large number of worlds and includes a nice Google Maps preview feature.
Mineways is not the first to offer a Minecraft model exporter, nor necessarily the best for export for rendering. Minepedia has a page about exporters. Here's more information on the ones I know about and related services. They may fit your needs better than Mineways:
- Printcraft is a cool idea: you go onto this server, build something with friends, then push the Print button and an STL file of your build is sent to you. No muss, no fuss. Meant for home and school 3D printers for the most part, since the STL comes without any colors.
- SourceCraft creates maps for Valve's Source engine, for games such as Team Fortress 2 and Garry's Mod, via Minecraft.
- CubeTeam is a free multiplayer online 3D modeling program that works in the browser. It's Minecraft meets CAD, with some worthwhile options such as smoothing your model or importing and voxelizing an existing 3D mesh.
- Jmc2obj is a Java-based (so multi-platform) exporter for rendering. It is actively developed, but I find I can't quite get the textures to attach properly to the surfaces. You do need to export textures first, typically giving you a single texture to work from, which is then applied to the model. If you get it going (let me know the secret), it has some nice features, nicer than Mineways in various ways.
- MCprep is a Blender python script that can improve model quality of Mineways and jmc2obj exports.
- dynmap has an option to export blocks, even custom blocks, to the OBJ format. I haven't tried it; let me know how you find it.
- Blokify is a free Minecraft-style modeler for the iPad. I found placing individual blocks a bit dicey, but that's because they've built in ways to fill in lines of blocks in a single go. You can email yourself the resulting STL file (though it didn't work for me). The blocks used are geometrically textured, so 3D print out with more than just simple flat surfaces.
- Mineblend - an add-on that extracts data from a world directly into Blender. I don't know how it compares to jmc2obj. If you use Blender, give both a try.
- MINECRAFT.print() - these guys were first to print Minecraft models, all glory to them! You run some python scripts from a command line to take a volume and turn it into an STL file. There's a hollowing function (their Companion Cube is not solid, thank heavens). Cody pointed out this nice little color export someone did using their scripts. All that said, the python script is years out of date and won't work on Minecraft version 1.2 on (Anvil format).
- Cura, the software for the Ultimaker 3D printer, has a Minecraft import option, step-by-step instructions here.
- Minecraft structure planner - written in Ruby, this is a basic exporter of STL files from schematics. It's the first program I know to export color models from Minecraft for 3D printing.
- Minecraft world exporter (old thread) - Mineways works only with worlds you have locally on your computer. If you can't download the multiplayer world you're in, use this mod to suck in whatever chunks you see.
- MagicaVoxel read Minecraft schematics and gives a nice rendering of them. It's best for large models, as it converts everything to colored blocks, no details.
- OptiFine is a mod that gives you some great additional rendering effects, GLSL Shaders works with it and gives even more rendering styles, and Sonic Ether's Unbelievable Shaders modifies these shaders further. Also give Eihort a look for older worlds, it's an easy-to-use standalone program that lets you see and explore much more of your world at once. MagicaVoxel Viewer reads in schematic files and does a nice job displaying the blocks (always as full blocks, though, no detail). Finally, Chunky is an amazing self-contained path-traced renderer: choose your chunks, load them, set the view and let 'er rip. Definitely try out the various options.
- FigurePrints - this commercial firm has a 3D application that lets you select and preview a chunk of your world all in one place, then order it directly. The user interface for selecting a chunk is a bit weak ("just type your coordinates in here"), but on the other hand what it does is simply grabs the area near where the player is located. Preview is in 3D, which is great, and performance is snappy. A cool thing is that it works in multiplayer, and you don't need access to the world files! Also, just select the texture pack you want, vs. having to use a terrainExt.png file. It also does half-blocks and stairs (but not fences). Downsides include not being able to control the export in various ways. There are also some texturing errors, perhaps fixed by now. But, this software can all but improve over time - if it gets people trying out 3D printing, great! Photos and more here.
- GrabIt is a platform for game developers to sell physical models direct to their users. It uses RenderFab 3D asset processing technology to fully automate the process of creating 3D print-ready models from any 3D data.
- WhiteClouds - this print service uses Mineways to export your Minecraft creations, among other 3D models. Worth a look for the cool pictures of models, along with Minecraft characters! There are a few pictures here, and model description.
- MineToys offers 3D prints of your character. More on how MineToys works here.
- Minecraft Schematic Store - buy and sell Minecraft schematics (note that Mineways has an Export Schematic option).
- Voxel is an iPad app that lets you design in voxels and send your model directly to Sculpteo for printing.
- 3DTin - it's not Minecraft, but lets you build with cubes and has a connection to 3D printing. Build your model out of blocks inside this web app and upload to a 3D print service.
- mc2obj (documentation and source here) - mentioned mostly for historical purposes, it has been superseded by jmc2obj. This utility pulls in the specified Minecraft world data and makes an OBJ file. It includes true geometry vs. Mineways' whole block orientation.
- mcobj - again mentioned for historical purposes, the first-known exporter. There is a Blender tutorial and a gallery of results. It has command-line and dialog versions. Source available. It didn't apply textures.
- Thingiverse - this site contains a bunch of Minecraft-related models if you are looking for things to print. I think this one is brilliant.
- Minecraft Reality sadly doesn't seem to be around any longer, but the demos of Minecraft objects inserted into the real world are cool to look at. Wait for Minecraft Earth, coming out a mere seven years after this article.
Minecraft Bedrock SupportMineways works on only Minecraft Java (aka Classic) Edition worlds. Minecraft Bedrock Edition, once known as the Pocket Edition (or MCPE, or Pocket/Windows 10 Edition), uses an entire different database format for its worlds, called LevelDB. This section describes how to convert a Minecraft Bedrock world to a Minecraft Java Edition one so that Mineways can read it.
There are various converters out there. The one I focus on here is MCCToolChest PE. Also, MCEdit has worked in the past, but it comes and goes. Another possibility is to find some way to convert your model to the Schematic file format, which Mineways also reads. For consoles, you might try out this utility (old page), or this one.
Let's go with MCCToolChest PE. You download it, install, and run. If you get an error about some missing DLL, you may also need to install the VS 2015 C++ Runtime. Once running, do the following in MCC ToolChest - PE:
- Select "File | Open" and choose the Bedrock world you want to convert. It should read in, and you'll see "level.dat", "players", etc. listed on the left. If you don't see the world you want to convert, you'll need to (somehow) get it to your PC and find its path via "File | Open" and "Select Folder."
- Select "Tools | Convert -> To Java." A large dialog box appears.
- For the "Minecraft Java world folder" at the top put a path where you want to create the converted world. For example, I might use "C:\Users\erich\AppData\Roaming\.minecraft\saves\bedrock_test\" - my user name is "erich" and the world directory name I want for the converted world is "bedrock_test." By putting the path "...\AppData\Roaming\.minecraft\saves\..." I am putting the converted world in the default directory for Minecraft Java worlds, which means it will then show up in Mineways' list of worlds automatically.
- Halfway down on the left of the dialog look for "Convert into." Change this from "Empty Dimension" to "Empty World."
- Click "Convert" at the bottom of the dialog. Cross fingers.
If you did get some error, try the "Help" button, it might actually help. I found not setting "Convert into" properly or not giving a good directory path can give errors.
Note that this tool can also convert from Java to Bedrock, if that's of interest. This video goes through the steps for that process.
Structure Block ExportYou can also export 3D data from (only) the Bedrock Edition directly to a 3D model file format, the glTF binary format. Give yourself a structure block in Minecraft by typing the command "/give @s structure_block". Place this block near the area you want to export, then right-click it. A dialog comes up in which you can specify the size of the export (never larger than 32x32x32, even if you set it higher), the offset, and the file name to export to, along with some other options. This file can then be viewed by the built-in Paint 3D program and be converted and loaded by many other programs in the glTF ecosystem.
Keyboard Shortcut KeysThe quick reference of handy shortcuts is here, with the full list here. Most operations in Mineways can be done with the mouse: left button drag and mouse wheel for viewing, middle mouse click for setting the depth to whatever is at that location, right mouse selects a region to export. If you don't have a right mouse button, hold Control down and use the left mouse button. Instead of using the height sliders at the top, using the mousewheel with the Control key down changes the depth, with Shift down changes the max. height (this second mode can be slow, since the map is regenerated). More on mouse controls in the Selection section.
- Version 1.0, 12/24/2011 - exe, source
- Version 1.01, 12/27/2011 - exe, source - fixed depth going to -1, added warnings about models being too large, increased map cache size, improved model summary information at top of model file.
- Version 1.02, 12/30/2011 - exe, source - added "hide all blocks" feature to color scheme dialog, fixed debug mode for separate parts so that it works properly if full textures are on (the textures get turned off) and so blocks always appear, don't export billboard torch if "Export all block types" is off.
- Version 1.03, 1/2/2012 - exe, source - Added check to see if world reads properly, warns if not; added snowy sides to grass blocks when covered with snow; changed to "illum 4" for Wavefront OBJ export.
- Version 1.04, 1/2/2012 - exe, source - Rendering gets some love: using "illum 4" kills Blender import, so back to "illum 2" for all but water, add "Tf" and remove "d" export; export "map_d" of the same texture map, making SAP Viewer work better with OBJ; change face offsets to be relative numbers instead of absolutes, so OBJ files can be added to each other.
- Version 1.05, 1/4/2012 - exe, source - Added two options: F7 makes little things like flowers and mushrooms visible on the map, and under File is "Select terrain.png for export", so a different terrain.png file can be used. Do not set the transmittance when using full textures for glass (assumes a cutout for glass). Other little menu cleanups, like what key selects the menu item.
- Version 1.06, 1/8/2012 - exe, source, Mac - Major bug fixes: bubble population problem, group allocation, proper display of different neighboring transparent objects, sloped powered rails not displaying properly for printing, mushrooms not displaying as billboards for rendering. Added units selection for output. Added automatic ZIP creation for export. Separated cutouts from transparent blocks. Corrected export of Tf for OBJ material file. Added separation of textures into RGB and RGBA and alpha-only for better rendering import to 3DS MAX. Added "frosted detail" physical material.
- Version 1.07, 1/9/2012 - exe, source - If blocks were turned off and "seal off entrances" was used, some of the hidden blocks would reappear; fixed, and guard code added. If a warning was flagged, a ZIP file is not created; changed so that the zip file is always created.
- Version 1.08, 1/10/2012 - exe, source - Files zipped before errors reported, output only those textures needed (and RGB for 3D printing instead of RGBA). Added fire billboard (your terrain.png must include it). Added dead bush and fern billboards.
- Version 1.09, 1/11/2012 - exe, source, Mac - Bug fix: was saving VRML PNG twice. Features: added Materialise Magics as a color STL export format, defaulting to the settings i.materialise prefers. All STL now defaults to mm units, as this seems to be a common choice.
- Version 1.10, 1/18/2012 - exe, source, Mac - Bug fix: default texture output not set for printing single-material OBJ. Fixed terrain.png read error message. Features: added emitter Ke output for emitters, though currently always '0 0 0'; this makes for easy identification and editing of emitters. Added internally a static, absoluteIndices, to allow positive indices to be output for OBJ files.
- Version 1.11, 1/19/2012 - exe, source, Mac - Bug fixes: spaces in texture file names baffles Shapeways' parser, so replaced with underlines; Wavefront OBJ "single material" output replaced by "true spec", where Ka and Kd are set to 0.2 and 1.0 for all materials - looks better in the SAP Viewer Complete. I also made "true spec" output absolute indices, for those readers that can't handle relative ones.
- Version 1.12, 1/25/2012 - exe, source, Mac - Bug fixes: half slabs of wood, sandstone, and other materials were all showing up as stone. Stronghold bricks were never cracked or mossy. Enhancements: "true specification" OBJ files are now output by default, since I figured out how to turn on previewing in Blender (see the tutorial). Blocks are now 1 meter in size when output for rendering, a scale that most rendering systems prefer and that I originally meant to be there.
- Version 1.13, 1/28/2012 - exe, source, Mac - Improvements: you can reload your world by hitting the "R" key now. Loading a different world will recenter at spawn and unzoom the view. Bug fixes: Major fix is that wide characters are now supported on file read and write, which means characters such as "åëîõú" can be used in file names. These get simplified for material and texture file names, since those need to be UTF8 (well, more UTF7) for OBJ and WRL files. Fixed bugs with spaces in file paths. Resolved color mismatches for solid color output. Fixed a color problem with slabs when using solid colors (appeared in v1.12). Redstone torches were always flattened, now they appear properly in rendering output. Flames are now exported to be at the edge of blocks. OBJ export always has Y as up, for easier print preview with G3D. When exporting Magics STL without colors the header is made simpler, so the object does not preview as black.
- Version 1.14, 2/4/2012 - minor bug fix: extremely large chunks (those with say 100 chests full of objects) would not decode; fixed by increasing CHUNK_INFLATE_MAX. Improve selection highlighting: the selected area is always shown, and if some blocks are not selected the user is warned and corrective action applied (moving Bottom depth down). Note that when the depth is moved down, it is conservative, including visibility down deep holes, for example. Improve texture pack import: avoid using bad water, lava, and file tiles in custom terrain.png files - see notes on terrain.png. Statistics about the print's cost are now optionally displayed at the end of export.
- Version 1.15, 2/15/2012 - source, Mac -bug fix: scale error on warning of "too small" model for colored sandstone; Shapeways doesn't appear to enforce this rule, though. Fixed vines to export in a more reasonable fashion: composited with underlying objects and underneath trees, changed color, made background grass. However, vines still extend out beyond trees (see bug list). Removed right-mouse click for assigning "Bottom" height, as it's confusing and redundant; just use middle-mouse instead. Change "Z is up" to be default for i.materialise STL models. Add Show size in inches and centimeters in printout dialog. Fixed dragon egg tile location. Added beta jungle tile support in optional terrain_jungle.png: 9,9 wood, 4-5,12 leaves, 14,1 saplings. Replaced terrain.png with the game's default terrain.png plus flames, as it's better for printing. Added other terrain.png options. Removed alpha cleanup for print export, as it's unnecessary.
- Version 2.0, 3/17/2012 - source, Mac - Anvil support: if you use Minecraft 1.2 or newer, use 2.x, else use 1.15. Hats off to Sean Kasun and some anonymous githubber, who did the heavy lifting in the conversion to Anvil. Source code uploaded to github. Old North is now East. Added redstone lamps, added Sphax PureBDcraft and LB Photorealism terrain.png files and updated the rest to Minecraft 1.2.3, as possible. Fixes: now uses a little less memory in a few places, to help large exports. Repeater/wire connection fixed so that wires properly attach to only the ends of repeaters, not the sides. What used to be East is now North (the sun changed where it rose some time ago).
- Version 2.01, 3/21/2012 - source, Mac - fixed various height bugs that slipped through the cracks. Wool now doesn't lose its color above height 127, for example.
- Version 2.02, 3/22/2012 - source, Mac - Updated to 1.2.4: added circle brick, different wood planks, and sandstone variants. Fix: swap spruce and birch saplings.
- Version 2.03, 3/23/2012 - exe, source, Mac - Improvement: added a "Lower depth" slider to the user interface, making depth selection obvious and easier (thanks to Adrian Alan Brown for the suggestion). Misa textures updated to 1.2.4 (Coterie, Doku, LB, and Sphax have not been updated).
- Version 2.04, 4/3/2012 - exe, source - New option: whether to create the model files themselves. By default, VRML printing now exports only the zip, because people often upload the wrong file to Shapeways. If you want to preview the model, just check the "Create files themselves" checkbox. Loading a new world turns off the selection and resets depths. All terrain textures now updated to 1.2.4.
- Version 2.05, 4/12/2012 - exe, source - Minor fix for rendering, only: vines are all turned into billboards. Vines are still a little funky for printing, but you'll never notice.
- Version 2.06, 6/19/2012 - exe, source - Improvements: The lower depth is now autoadjusted for every new selection, and autoadjustment can be turned off. VRML rendering output is now grouped by material, for a bit more Cinema 4D support. VRML now exports to solid color and single color formats, for Ponoko support - many thanks to Ariock for and Ponoko for their help. VRML files now write out squares instead of triangles, reducing ZIP file size by about 20%. VRML files are now generated by default again, for previewing (generating just the ZIP is good for utter newbies, but a pain for everyone else). Various format bug fixes, including making rich color and floating object debugging mode work again. Unknown block ID check added, to future-proof Mineways and warn users of unknown block types. Week24 beta block additions are unofficially supported, though I'm ignoring the cocoa plant, and block of emerald is semi-supported (it conflicts with the old chest lid texture location - grrr).
- Version 2.07, 6/26/2012 - exe, source - bug fix: huge mushrooms were not textured correctly, now they are.
- Version 2.08, 7/9/2012 - exe, source - New features: individual block export and block test world added. See this section of the documentation. Bug fixes: fixed export of redstone torches and repeaters, made vines always properly cover the underside of blocks, and made the bed texturing slightly better.
- Version 2.09, 7/20/2012 - exe, source - Many new blocks have been added for rendering and for printing. These blocks are exported by default for rendering, and can be exported for 3D printing, by using the "Export lesser blocks" option. This feature is experimental (fences and fence gates are highly likely to break off, for example), and works with Sculpteo but not Shapeways. See more details here. Flowers, mushrooms, tall grass, dead bush, saplings, and stems now are visible on the map and print as flattened decals (if you don't like this, disable using a color scheme).
You can export again instantly with the same options and filename by using Control-X (or the File menu item). This is useful when adjusting bounds, fixing the world, reloading ("R"), or changing the color scheme and then re-exporting. File path is now retained for normal file export, also making adjusting easier. Material output has been simplified for OBJ, to improve import into Blender (though water now looks more boring in G3D - sorry; and just uncomment "illum" in the .mtl file). Absolute and relative OBJ have changed position on the file type selector, and 3D print firm names added when exporting for 3D printing. Changed default terrain.png to support all new Minecraft 1.3 blocks (note Emerald Block is shifted). Numerous fixes to [Block Test World] and block IDs added. Memory use has been considerably reduced, half or less of previous typical use.
Here's the list of blocks which now have correct geometry: slabs, stairs, fences and gates, farmland, signs, doors (but not for 3D print - too thin), pressure plates, buttons, snow, trapdoors, end portal frames, cocoa plants, and cake.
- Version 2.10, 7/24/2012 - exe, source - Fences, gates, doors, trapdoors, and sign posts are now exported for printing when the "lesser" option is used; see more details here. Options for tailoring OBJ export, and improved documentation on exporting to renderers.
- Version 2.11, 8/2/2012 - exe, source - Added water and lava level export that matches Minecraft's; this always exports for rendering, and for 3D printing only when the "lesser" option is checked. Support sideways logs and upside-down levers in 1.3.1. Bug fixes: flipped tiles on "lesser" objects so they properly matched left and right. Rewrite of the UV texture coordinate system in anticipation of major changes for full support of Minecraft 1.3.1 (modest reduction of number of UV coordinates saved). Mineways will mostly work with MC 1.3.1, but note that 1.3.1 texture packs used with Mineways will make chests disappear (thanks, Mojang). Major rework is needed to fix this mismatch; the default texture pack will work fine for everything but Emerald blocks.
- Version 2.12, 8/3/2012 - exe, source - critical bug fix for VRML export, I introduced a bug in version 2.11, in which the first few faces would not be exported. Thanks to Jonah Shafer for reporting this bug.
- Version 2.13, 8/4/2012 - exe, source - Shapeways redesigned its upload page, now millimeters is the default model unit. Changed Mineways to export in millimeters by default, rewrote the documentation for Shapeways export.
- Version 2.14, 8/4/2012 - exe, source - Vines not exporting for 3D printing when the "lesser" feature was on. Fixed. Thanks to Sterling Babcock for reporting this bug.
- Version 2.15, 8/28/2012 - exe, source - Added "fatten lesser blocks" option, so that small features that are printed are less likely to snap off during manufacture. Removed "flatten blocks" option, since it's never turned off by anyone nowadays. Numerous minor tiled texture fixes. Fixed farmland output for printing. Added correct bed, cactus, and redstone repeater output for rendering and "lesser" 3D printing. Added sloped rails for 3D printing when "lesser" is on. Cauldrons with water levels added. Dragon egg geometry added. Command and beacon blocks added (default terrain.png only; beacon block is currently at 8,11), along with cobblestone walls, flower pots, carrots, potatoes, and wooden buttons.
- Version 2.16, 9/8/2012 - source, Mac - bug fixes: fixed 3D printing color export for Sculpteo (OBJ) format viewed in SAP Viewer, fixed output of relative texture coordinates for OBJ export. Fixed color schemes so that old color schemes will auto-update when used with newer worlds. Provided guidance to Mac users looking for their world directory (still trying to figure out how to make this happen automatically). Added Xzip/unzip in anticipation of someday reading texture packs directly for textures. Added Ender Chest, but only for default terrain.png. Thanks to Sterling Babcock for bug reports and the Ender Chest texture addition.
- Version 2.17, 9/11/2012 - exe, source - bug fixes: for cobblestone walls, pillars were not appearing on straight walls when objects were placed above the walls (thanks again to Sterling Babcock for the bug report). Also, in version 2.16 I tried to fix a problem for the Mac where it crashes for some users, possibly due to a memory use improvement introduced in version 2.09. I've turned this memory improvement back on in this version as it doesn't seem to matter for the crash.
- Version 2.18, 9/27/2012 - exe, source - Output block size in statistics popup. Warn user if unknown block type is encountered. Add a "head block" placeholder (pumpkin) for now; it turns out to be hard to add the new beta's head blocks. Bug fixes: fix the scale dialog (the radio boxes got separated from one another). Turn default options (connect blocks, delete floaters) back on when "lesser blocks" option is turned off. Attempt to find Minecraft worlds a bit better on the Mac (no promises...). Remove warning about floaters when "lesser blocks" is used.
- Version 2.19, 10/17/2012 - exe, source - Added anvil. Fixed terrain.png to avoid rendering errors. Fixed crash on solid color export for rendering, and proper export for 3D printing. Added fire tile for 3D printing. Added path information to .OBJ header. Fixed texturing and placement errors for doors, cauldrons, and cocoa. Fixed texture clamping for furnaces, bed, and cauldron. Added color expansion (bleeding a decal's texture colors outward into the transparent parts) to improve rendering quality on various renderers. G3D/SAP export also now performs further color expansion. Improved error messages for Mac version - I still don't know how to detect Mac paths using MFC and WINE; advice appreciated. Added beta's stair "trimming" rules (where stairs at right angles will trim away part of the upper step), but this feature will not be enabled until 1.4 is released.
- Version 2.20, 11/30/2012 - exe, source - Major feature addition: schematic export. See the relevant documentation for more information. Added version number to output file's comment header, to help in debugging. Fixed physical material name in output file's comment header (was printing just one character instead of the string). Fixed error message warning of bad blocks: further code added to handle this problem (thanks to Josh Smith for pointing out the problem). There is now an "unknown block" type that will show up on the map and on export, which looks like bedrock. As usual, you can remove these blocks by using a color scheme. Fixed bedrock properties (was listed as having transparency).
- Version 2.21, 12/11/2012 - exe, source - Stupid bug fix: I managed to break rendering support a bit, causing export to use the printing code path (slower and unnecessary). Now it works again. Minor feature addition: Sculpteo exports now have a somewhat better price displayed, but since I don't know their formula, it's still approximate.
- Version 2.22, 1/21/2013 - source, Mac - Bug fix: sometimes unknown blocks caused a timing error, making the "bad block" message repeat many times. Fixed, I believe... (thanks to Michael Leone for reporting this bug)
- Version 2.23, 9/3/2013 - source, Mac - Enable stairs to join under the 1.4 rules. Added "copy" for color schemes, and "OK" buttons. Added blocks up through 1.6.2, but mostly for mapping - the textures and some behaviors of the new blocks are not supported yet. Soon! Fixed "affects water level" property for some blocks. Fixed up direction stats format.
- Version 3.0, 10/11/2013 - exe, source - 1.6 support: at last, I tackled the new way Minecraft stores textures. This release no longer uses terrain.png files. Due to rules and format changes, an older version may serve you better: for 1.2 to 1.3 Minecraft worlds, use Mineways 2.22; for Minecraft 1.1 or earlier, use Mineways 1.15 (I don't even have a copy of either any more.... Changes: began TileMaker project to make custom terrain textures from texture packs. // Added mapping (only) for 1.7 - geometry to follow soon. // Setting a color scheme's air color sets empty spaces on the map to this color (even if the air is still transparent). This can be handy for making a nice background color for railroad maps, for example. // When a new world is loaded, the view is switched to the Overworld level, to avoid confusion. // Torches now have tops when exported for rendering. // New Shapeways materials added and cleaned up. // Fattened wood fences for 3D printing are now exported as stone wall shapes, for stronger support. // Mossy fences are now mossy for "non-detailed" 3D printing. // Fixed chest lock placement, and creation on test world. // Nether brick and quartz slabs/double slabs added. // Detector and activator rails now have active states. // Lots of other fixes you'll never notice.
- Version 3.01, 10/17/2013 - exe, source - Serious color scheme crash bug fixed, due to array overrun. // The TileMaker is now available to help you make your own textures - see documentation. // Fire has been improved with more billboards, similar to Minecraft's style. // Torches are now sheared in Minecraft style instead of rotated. // The beacon's true geometry has been added for rendering.
- Version 3.02, 10/25/2013 - source, Mac - Move to 1.7.2, adding all its blocks (exceptions: flower pots with acacia and dark oak saplings not supported). No looking back, roses are replaced by poppies and April Fool's locked chests are replaced by stained glass blocks. // True geometry added for glass panes, iron bars, levers, and brewing stands. // Redstone wires potentially running up block sides now are properly cut or not cut by various block types placed above them. // Many little texture fixes and rationalization of the code. For example, some billboarded objects (e.g., brewing stands, iron bars) now have a tiny epsilon between their front and back faces, to avoid z-fighting in G3D - I'm not sure this helps others.
- Version 3.03, 11/17/2013 - exe, source - Avoid crash when old-style terrain.png is used; warnings system improved. // Updated new Shapeways ceramics costs, and improved estimation by including partial block export. // Updated terrainExt*.png files Coterie, Doku, and BD Craft.
- Version 3.04, 12/10/2013 - exe, source - Allow export of partial blocks when saving without textures. // Set Ke and map_Ke for emitters' materials for OBJ, giving a better look when using the G3D viewer. // Properly output color swatches and other neglected modes. // Fix world name output for OBJ.
- Version 3.05, 1/1/2014 - source, Mac - Export "lesser" blocks more efficiently, removing many invisible polygons and so improving 3D print conversion. Added "Import Settings" feature, which lets you read in a previously-exported Mineways file and match its export settings. Various bug fixes: proper export of "connect all edges", proper export of solid-color renderings, fixed some error messages to properly display.
- Version 3.06, 1/27/2014 - exe, source - Added option under "Help" that minimizes the amount of memory used during export. Use this option if you're running out of memory on large exports. This is not on by default, as this option will make exports take a few seconds longer. // Share some common export settings (color, material, block size, and more) among some related file formats. This is useful for when you export to both Shapeways and Sculpteo, for example. // Free the input TerrainExt.png file as soon as we're done with it. // Added automatic cache resizing and recovery for large map display.
- Version 3.07, 5/29/2014 - exe, source, Mac - If you can't use the right mouse button, holding down "Control" will make the left mouse button act as the right mouse. // New 1.8 blocks added: Andesite, Diorite, Granite, Slime, Iron Trapdoor. // Piston head now properly created as geometry. // Trapdoors properly render at top of block. // Fences and walls properly join with transparent blocks. // Out of memory conditions now flagged as errors.
- Version 4.00, 6/18/2014 - exe, source - 64 bits, at last! Mineways and TileMaker are now 64-bit executables. Now large exports will not fail due to running out of memory. Use the *32.exe version if you can't run 64 bits for some reason. Programmer's notes: switched to all C++ and a single build directory and project. 64-bit Zlib static library from here, wonderful LodePNG (a replacement for libpng) from here. // Minor change: "Set terrain file" now starts in the directory where mineways.exe itself is located.
- Version 4.01, 6/20/2014 - exe, source - Fixed importer so that upper height is set properly. // Increased size of progress bar, so that progress is more visible for huge exports. (thanks to Adrian Cowherd for the suggestion.)
- Version 4.02, 6/22/2014 - exe, source, Mac 32-bit only - Added blender_mineways.py script to vastly simplify Blender import of Mineways models (thanks to Wyatt Jameson and Nicky for this script). // Fixed extremely slow memory freeing of face records by replacing face allocation with my own pool system; large exports now proceed much faster. // Finally fixed the "two selections" bug, where if you made a selection and panned so it was offscreen, it wouldn't get cleared and could scroll back onto the screen, looking as if there were two selections.
- Version 4.03, 8/24/2014 - exe, source, Mac 32-bit only - Added more 1.8 beta blocks, including prismarine, sea lantern blocks, banners (minimal), red sandstone, wet sponges, coarse dirt, new wood fencegates, fences, and doors. Change block names to match Minecraft's names. Added experimental colored plastic material and updated material costs and properties for Shapeways. Fixed wheat export for wheat near villages (was appearing as Netherrack); thanks to Duncan Alimchandani for reporting this bug. Fixed anvil rotation, better door texture borders, and other obsessive bug fixing. Improved "missing TerrainExt.png" warning for Mac users. Changed PNG exporter to optimize PNG file export, giving smaller files (note that older versions of G3D may not read these files, so get the latest). Allow TileMaker to convert the color black for a texture to mean an alpha of 0.0. Updated texture packs as possible. New Mac version from Psp4804 that no longer requires X11 or xQuartz.
- Version 4.04, 9/1/2014 - exe, source - Fixed obscure bug: sloped rails exported to a detailed 3D print export had bottoms of the blocks missing, causing models to not be watertight. Small cleanups on when texture coordinates are generated, which should make some export files a tiny bit smaller. Attempted yet again to find the Mac Minecraft world saves area.
- Version 4.05, 9/20/2014 - exe, source - Fixed stair corner export bug; thanks to Chris Hutton for reporting it. Added name of world opened to title bar. Began biome work: biomes now read but are not yet interpreted. Fixed orientation of vines for south and east sides when rendering. Colors for grass, leaves, vines, stems, lily pads all adjusted to be closer to Minecraft's. Spruce and birch leaves now the proper hue of green for each.
- Version 4.06, 9/25/2014 - exe, source - Fixed biome read bug; biome and section order seems to be a bit arbitrary for some reason. Thanks to Tony R. for reporting this bug. Sorry, biomes not implemented yet.
- Version 4.07, 10/14/2014 - exe, source, Mac 32-bit only - the little big one.
- Added Windows 8 executable, mineways_windows8.exe. You may need to install the 64-bit version of the Visual Studio 2013 redistributables to be able to run it.
- Added biome mapping mode: View | Show Biomes (or F8). See documentation for details.
- When biomes are displayed, elevation shading takes into account the altitude's influence on temperature for the biome. This effect is subtle, but it's there.
- Biome of the center of the area chosen for export can be used to modify the grass, trees, and water color (yes, I'm getting closer to exporting multiple biomes, but that's hard).
- Tilemaker 2.01: the grass_side_overlay.png texture is now used to properly form sides of grass blocks from scratch. If you make your own tile sets, you would be wise to rerun this new Tilemaker for best results.
- UI improvements: arrow cursor shown when resizing is available.
- Made mapping program output more (and better) colors, e.g., colored glass, carpet, and stained clay.
- Added more map description (at lower left of window) for cursor location for tree types, flowers, and other blocks:
- Block ID and data value shown for cursor location when View | Show All Objects (F7) is on.
- Biome type is shown when View | Show Biomes(F8) is on.
- Fixed semitransparent display: semitransparent objects now blend properly, and the cursor will report on only fully solid objects.
- Color of grass, tree leaves, and other green objects are now truer to their Minecraft counterparts.
- On the map, however, trees are shown in considerably different colors than used for export in order to make them visible vs. the ground, and easier to tell species apart. If you don't like these colors, turn on Biome display (F8) or make a color scheme for oak leaves (block 18) and acacia leaves (block 161) and set the color to say #6fac2d - a small color change of any sort will turn off this leaf display feature.
- Better (I hope) block adding algorithm. When two blocks' edges touch diagonally on a horizontal edge and need to be joined, favor adding a block below vs. a block above.
- Updated costs to match Shapeways' new prices for strong plastics. Shapeways' own site is misreporting machine volume needed, however, so there is currently a price mismatch.
- Changed export dialog so that if various values are changed, the corresponding scale option is selected. More export options are grayed out for certain output modes that they don't influence (e.g., biome color export works only when full textures are used).
- Made export dialog short and wide, so that it works better on 800x600 displays. Improved settings import instruction popup.
- Emitter color increased to work with new G3D viewer.
- Updated documentation, fixed stale links, added new prints to gallery.
- Bug fixes:
- Fix out-of-bounds data access for chest export in 3D printing.
- Mouse selection off left or top edge now no longer wraps around.
- "Debug floating parts" mode was crashing due to there now being more than 196 block types.
- "Import settings" now properly reads files created using the cost or wall thickness criteria.
- Progress meter fix, so progress now doesn't go backward.
- Old double chests (without a data value) fixed to properly join up. Interestingly, these old chests simply disappear, they can't be seen in 1.8, even though their data is still saved in the chunks.
- Internal cleanups: removed extra fake wool block types, removed duplicate block definition data structures, increased map block cache size 5x for the 64-bit version, general C++ification of code from C.
- Version 4.08, 10/22/2014 - exe, source, Mac 32-bit only - Major Mac version fix: worlds and terrainExt.png texture file is now found properly. Wall banners now display (with no pattern or color). Added normal per vertex for OBJ and fixed it for STL output, so that the GLC Player can display models better. Fixed vine and anvil normals. More object names are now displayed. Fixed color schemes so that old color schemes update properly to 1.8 format. Minor fixes to a few biome temperatures. Converted code's tabs to spaces for easier Github viewing.
- Version 4.09, 1/6/2015 - exe, source, Mac 32-bit only - Fixed stairs output to obey all Minecraft rules (thanks to James Ward for reporting this). Fixed carpets, snow, and other thin covers to export properly as lesser blocks for 3D printing (thanks to Justin F. for reporting this). Fixed output of cocoa plant pods. Made objects all watertight when exporting using the lesser blocks option. Made the individual blocks option work for all blocks. Hollowing is now off by default for STL export, as home printers usually don't want to use this operation. Changed OBJ material output to use a white color when a texture is output, since these two elements are multiplied together for GLC display. Improved error messages, especially for reading PNGs. Updated to Shapeways' new cost scheme for white plastic prints; mine is an approximation of their complex algorithm, but gets fairly close. Synced to latest Shapeways constraint data. Added popular block texture names as alternate tile names to TileMaker by using the '-a' option, and give better diagnostics about unrecognized tile names.
- Version 4.10, 5/22/2015 - exe, source - Fixed initial view for some worlds, where spawn point was not being read in correctly (thanks to Bob Irving for reporting this). Fixed code to avoid infinite loop when modded world data is encountered (thanks to Julian Drawdy for reporting this).
- Version 4.11, 7/18/2015 - exe, Mac 32-bit only(flawed: missing terrainExt.png), source - Fixed serious bug in STL export, where "individual blocks" was always being flagged as on; this causes uploaded models to look "skeletal." Improve Mac error for unassigned terrainExt.png file, explaining what to do next.
- Version 4.12, 9/10/2015 - exe, source - Added cycles_mineways.py script to set materials for Blender's Cycles renderer (thanks to Jonathan Edelman for this script), and updated documentation. Improved water export for printing, so that surface is manifold. Lengthened the "unassigned terrainExt.png" error message yet again, to help people out.
- Version 4.13, 11/4/2015 - exe, Mac 32-bit only, source - Folded the terrainExt.png's data into the program itself. Now Mac users will never have to dig around to find this file. By default, if a terrainExt.png file exists in the same directory as the executable, it will be read in; if not found, the internal default terrainExt data will be used instead. This allows you to still customize the terrainExt.png file and have it get used by default. But, it also means that you can run Mineways entirely from the .exe itself, so on Windows could run it from a zip file, for example. // Fixed flower pot and cauldron export to avoid polygon overlaps and non-manifold surfaces.
- Version 4.14, 1/9/2016 - exe, Mac 32-bit only, source - Made the "bleed" process for cutout objects (flowers, mushrooms, and more) always happen; it used to be done only when the G3D material was selected. Performing bleeding keeps the fringes of these objects their proper color. See this and this model to see the difference, and for further explanation. Added an option to make tree leaves solid for rendering, which vastly reduces polygon count for forests. Added an option to not export the bottom and side "box limit" polygons for rendering, to lower the polygon count and allow better export tiling. Changed the alpha map to have the alpha value in all four channels, so that Sketchfab properly displays the model by default. Increased thickness of "Block Test World" for better testing. Fixed bug in version number output to the various model files (there since version 2.24). Other minor fixes to vines and to the user interface.
- Version 4.15, 3/7/2016 - exe, Mac 32-bit only, source - Minecraft 1.9 blocks added. 1.9-specific changes not added (these will come in 5.0): new "single" iron bars and glass panes, new redstone line patterns, and new still water texture next to glass. // "The Void" biome added (well, that's been in there for awhile). Fixed biome button turning off after an export. Fixed crash when "richer color textures" selected. Fixed haystack to display properly when horizontal. Fixed potato and carrot growth to properly match tiles. Added up and down buttons. Fixed pack ice to properly join to fences. Fixed fattened fences to always output their posts, and cobblestone walls to remove the post only when the fence forms a line. Pumpkin and jack o' lantern stems on whole blocks now properly oriented. Glass panes now properly don't connect to water, lava, and chests. // Improved world search for Mac users (from Aurélien Chatelain). "Show all" now shades transparent objects and mouse-over shows these objects. Increase block status window as application is resized to be wider. Fixed bug of File|Open... not working after using File|Open World. Properly update mouse-over status when changing view. Fixed bugs and inefficiencies related to switching to Nether and The End. Fix: if you switch from color STL to ASCII STL exporting, the material is now set to have no color and so will not give a warning. Escape key deselects area selected. F1 and ? pop up "About" dialog. // TileMaker now has two more options, -s and -S, that produce a solid (average) color terrainExt.png file. The "-S" option preserves the alpha cutouts. This texture allows greater control of solid color blocks, as you can set every face type as desired by changing its tile when using TileMaker, versus using the single color used for a particular block ID. // Latest Blender Cycles importer script included.
- Version 4.16, 3/13/2016 - exe, Mac 32-bit only, source - Sketchfab export option added. Added Modern HD texture file terrainExt_ModernHD.png (thanks for permission, Mikeyto1o) and removed unmaintained LB Photorealism texture file.
- Version 4.17, 4/24/2016 - exe, source - The world name and the world save folder name are both displayed for "Open World," since I was finding the world folder name was not sufficient. Moved Reload World menu item to be under File. Fixed export of rails, redstone, snow, and other "flat" decals onto partial blocks such as slabs. Two fixes with fluid export for detailed 3D printing; the mesh is now properly formed (I think). Removed all solid color texture output, freeing up a large area of the texture for "composite" tiles, such as redstone on logs, railway tiles, and more. The +/- keys (along with Page Up/Down and E/Q, as before) now zoom in and out. This is handy for small laptop keyboards, and because I forget that E and Q zoom. Color Scheme now has a "Hide Tree Blocks" to remove all log and leaf blocks, making terrain printing easier (trees tend to be delicate and break off). Sculpteo's prices have come down about 20% for colored prints, so the price estimate has been adjusted. // Deleted Windows8 executable; see the installation notes if you think you need it. You should just install the VC redistributables described there.
- Version 5.00, 6/10/2016 - exe, source
- Moved to Windows 10 redistributables. If you get an error about MSVCR120.DLL being missing, you'll need to install the Microsoft Visual C++ 2013 Redistributable Package for your system. Select vcredist_x64.exe for your 64-bit system, vcredist_x86.exe if your system is 32 bits. To find out if your computer is running a 32-bit or 64-bit version of Windows, follow the instructions here, which come down to "hold down the Windows key and then click the Pause|Break key, then look for System type".
- Added scripting support. This is a huge deal if you're a serious user.
- Added quick reference page.
- Added a separate G3D viewer download, explained here, with special controls to maintain Minecraft's blocky look.
- Added material per type or per block as an option for individual block export.
- Fixed rendering output to be 1 meter per block. If you want it back the old way, change "Make each block" back to 100 mm from 1000. You can even use scripting at startup to do this automatically.
- Changed torch shear to rotate the torch instead, to match torches in 1.8 and newer.
- Made signs thinner to match Minecraft's.
- Changed hotkey to close app from Ctrl-W to Ctrl-Q (quit), to get it further away from other keys.
- Removed "B" hotkey - I don't even recall its intent.
- Fixed export scale radio button control (fix tab order).
- Fixed bug introduced in 4.17 where single-material export failed.
- Generalized "Import Settings" code to be more flexible and forgiving: it will now read in the world, terrain file, and color scheme from a previously-exported model file, as possible (4.18 files always set all three of these).
- Made names of blocks exactly match those at the Minecraft wiki, so they can be used in scripts.
- Fixed lesser blocks case of water on top of an upper slab, so that top of slab gets removed.
- Cleaned up step export for 3D printing, when using the "lesser blocks" mode. A few less faces are now exported when adjoining stair blocks match exactly, which may help some 3D printer slicers get it right.
- Lots of other little changes, hopefully for the better.
- Version 5.01, 7/5/2016 - exe, Mac 32-bit only, source.
See this model for a runthrough of the improvements made to rendering export.
- Added 1.10 blocks.
- Full 1.9 support, leaving 1.8 truly behind: isolated iron bars and glass panes are now simple posts, redstone wire and overlay textures used, water overlay used.
- Added block face offset for rendering: instead of composite tiles, where a new texture is created for say a ladder on a wall, the ladder face is rendered offset by 1/16th. If you encounter z-fighting problems, turn "Create composite overlay faces" on.
- Torches simplified and improved: less polygons, work better with Sketchfab, Sphax, and other texture packages.
- Chests and ender chests now are properly created and fully recorded in TerrainExt.png.
- Redstone wires are now shown with their proper on or off state.
- Autocorrect for the level on initial selection now ignores semitransparent blocks by default, so including the bottom of lakes and coastlines. It also looks one block outside the border, so that cliffs are properly shown.
- Space bar now corrects the bottom height, ignoring transparent blocks, which is useful when adjusting the selection area. Holding shift with the space bar does the same, but pays attention to transparent blocks (better for 3D printing, where we don't care about the bottoms of lakes and oceans).
- Added "V" mode for script command "Select minimum height", see the docs.
- Water tile is now left as is, no longer modified by the alpha set in the color scheme.
- The enchanting table now is the proper size (no book, though).
- Pumpkin and melon stems fully rendered at maturity, and rotated to proper position. Color's still not exactly right for each... next version.
- Glass panes and iron bars properly sized and top and bottom edges rendered.
- Tripwire hooks (but not tripwires) added. Giant time suck, but now all blocks have a real rendering, not a stand-in decal.
- Flower pots emptied if version is 1.9 or higher (now that we can finally check the map version). I'll fix this fully someday. (thanks to JMY1000 for the report)
- Sunflower rotation angle fixed.
- Tiles stretched better for full block 3D printing export.
- Glowstone now does not chop redstone wire going over an edge.
- If a tile is not a power of two in width, TileMaker now flags an error and exits.
- Export full path to terrain file, for easier use when using Import Settings.
- Fixed chunk edge error when using "Create block faces at the borders".
- Reduced face loop storage size by about 30%.
- Removed default composite tiles, since the system generates these and there is now plenty of space for composites.
- Forced some pop-up messages to be topmost, since they're important and sometimes get lost.
- Added status information when script is run, showing file currently being exported.
- Plugged some small memory leaks.
- Removed tiles.h from TileMaker area, directly use the Mineways/Win version, to avoid file duplication.
- Documentation streamlined, putting more useful stuff first and consolidating troubleshooting.
- Moved Windows 32 version of Mineways to separate directory, included msvcr120.dll's for both versions.
- New icon! (thanks to JMY1000 for the idea)
- Version 5.02, 8/4/2016 - exe, Mac 32-bit only, source.
- Critical bug fix: properly find minimum height when selection is performed.
- Critical bug fix: schematic file export broken due to filtering out smaller blocks.
- Bug fix: Import Settings now will properly read in STL ".txt" information files, so work can be resumed.
- Bug fix: scripting export of schematic files now properly saves as a schematic.
- Bug fix: when a new world is loaded, properly display reset slider depths.
- Bug fix: ignore case when comparing most strings in scripting system.
- Improvement (I hope): "Custom printer" material added and used by STL export, set to PLA characteristics by default.
- Costs for volume & handling, currency, and minimum wall size can now be set by using script commands.
- Hardened clay (#159) changed to stained clay; tinted clay (#172) changed to hardened clay.
- Version 5.03, 8/22/2016 - exe, Mac 32-bit only, source.
- Serious bug fix: stairs improperly causing full faces to disappear, due to the data value of the stairs being cleared when output. That's what I get for trying to tidy up.
- The "Open..." command now reads in a schematic as a map, for ease of exporting.
- For schematics, only, Control-A will select the whole schematic model.
- If you save or rename your schematic file to have the world "repeat" in it, e.g., rename "eiffel.schematic" to "eiffelRepeat.schematic", the schematic will load and be repeated across the map, with a minimum one block gap between each model. This can be useful if you want to create a single 3D print file that has multiple copies of the model.
- FWIW, I've added to Planet Minecraft a schematic of the Block Test World that comes built-in to Mineways.
- The seal off entrances checkbox now automatically attempts to fill in small window and door openings in houses and fill the interiors, without having to place torches.
- Bug fix: properly select the correct color scheme when adding or deleting color schemes.
- Bug fix: properly mark The End as on when chosen from the menu.
- CyclesMineways scripts updated.
- Version 5.04, 10/7/2016 - exe, Mac 32-bit only, source.
- Stand-ins are in place for the Minecraft 1.11 beta observer and shulker boxes. The new textures for these are not yet integrated into Mineways, as I don't like to integrate blocks and their texture names until the release is official. For now you'll get something approximating these new blocks.
- Material subtypes can be output: for example, Stone has seven types. Normally only one material, "Stone", is output, but you can have "Stone", "Stone__1", "Stone__5" for each type used, by its data value.
- Command line option added: you can specify the folder where your Minecraft world save folders are stored, if you want to use another directory location. The format is -s directory. (Thanks to this redditor for this suggestion.)
- The selection box now shows against empty or missing blocks. (Thanks again to this redditor for this suggestion.)
- Flower pots are fully supported for rendering, as block entities are now read in. Reading in block entities was involved...
- Mob heads are properly scaled and positioned, but are still rendered as pumpkins. Adding the real heads is on the TODO list, but involves using unwrapped textures; the dragon head in particular is elaborate. Note that with Material subtypes feature the different heads will be identified by their material.
- Efficiency/bug fix: 3D print OBJ models were exporting with separate materials and groups. These are unnecessary, as is the alpha channel texture output. However, if exported using a single material, the alpha textures were getting used. Fixed.
- Import of models exported from the Nether and The End using Import Settings now switch to these world types on import. Only models exported from this or later versions will contain the "View Nether" and "View The End" header information needed for this to work.
- Automatic height adjustment when using Hide obscured (usually on in the Nether) now takes this feature into account, to give a better bottom starting height.
- Monster eggs now output mossy, cracked, and chiseled stone brick versions, a 1.7.2 change I finally noticed.
- End portal frames now show the eye of ender if present, and are rotated (though not 100% compliant, as I don't want to mess with adding a bunch of rotation flags).
- Pumpkins and Jack O' Lanterns now show the faceless varieties (data value 4).
- Centering the model around the origin now maintains coordinates. That is, if you use color schemes to select various blocks for export and centering is on, each export will use the same centered coordinates. Prior to this fix, each export would be centered around whatever blocks were output, meaning that different exports of the same volume would not align. Some renderers such as RenderMan need all transparent faces. This improvement lets you export water or other transparent objects so that they generate all faces, not just those faces that border air, though you have to perform two exports to do so. I might add yet another checkbox for having transparent surfaces always generate faces...
- Bug fix: A block with vines hanging on all 4 sides and with the bottom covered could potentially crash Mineways. Array sizes increased.
- Bug fix: If lesser block export is turned off for rendering, composite overlay must also be off, as the whole "small object" subsystem is not used. This bug caused a crash. (Thanks to this redditor for reporting this bug.)
- Bug fix: Anvil top blocks were output twice, causing the top of the anvil to not show correctly.
- Bug fix: Acacia and jungle saplings were getting turned into oak and spruce saplings, due to masking out the two high data value bits.
- Bug fixes: The export options for OBJ were getting trashed when VRML or STL export was done first. Also, some options that were supposed to be unchangeable could be changed. I think I fixed this system now...
- Bug fix: Areas with X or Z coordinates outside of the -1,000,000 to 1,000,000 range would give an out of memory error, due to some lazy bounds testing I put in. Changed 999999 to INT_MAX, -999999 to INT_MIN throughout the code. (Thanks to David Ng for reporting this bug.)
- Version 5.05, 11/2/2016 - exe, source.
- Fix the command line options: these were getting entirely ignored due to some dumb code I added in a previous release.
- Serious bug-proofing: avoid hanging if a bad level.dat file is encountered. Instead, ignore the world and warn the user. (Thanks to AttackPlayz for helping me track this down.)
- Fix highlight selection so that empty block locations (holes to infinity) are highlighted when selected, in keeping with 5.04's new highlighting display.
- Now that the G3D viewer doesn't need it, don't double the Ke material attribute values in OBJ output when the G3D material is used.
- Make transparent materials in OBJ output with a tiny bit of Ks reflectivity by default, which looks nicer in G3D.
- Version 5.06, 1/19/2017 - exe, source.
- Fix the test for player location so that purely server-side worlds can be loaded. (Thanks to Shannon Vaughn for help in finding this bug.)
- Give a better warning if an Education Edition world is detected, explaining how to proceed.
- Version 5.07, 6/4/2017 - exe, source.
- Properly cull unneeded geometry for inverted stairs. (Thanks to Vervez for reporting this bug.)
- Properly make stairs and other complex blocks have tops and bottoms output if at border when "create block faces at the borders" is on.
- Version 5.08, 6/5/2017 - exe, source.
- Subtract a bug, add another: fix gaps when an elevated slab is next to a normal step. (Thanks to Vervez for reporting this bug.)
- Version 5.09, 6/9/2017 - exe, source.
- Added observer and shulker box texture support, along with 1.12 beta glazed terracotta, concrete, and concrete powder textures.
- Version 5.10, 8/10/2017 - exe, Mac 32-bit only, source.
- Limited world list to 50 entries, as there seems to be a problem checking files if there are too many worlds in the "saves" directory.
- Provide more detailed and explicit instructions and information about errors when opening files.
- Use the backslash everywhere in the path for opening files, just in case that's a problem on some systems.
- Properly truncated world's name for Sketchfab title.
- Version 6.00, 8/1/2018 - exe, source.
Moved to Visual Studio 2017, Windows SDK 10.0.17134.12. Added 1.13 translation - note that schematic export from 1.13 is iffy, since schematic does not support the new blocks. Added brown and red mushroom blocks "all cap" and "all stem" modes. Podzol with snow on it now properly turns snowy on its sides. Properly show bin direction for activated hoppers. Placed the active comparator output torch down two pixels to proper position. Fixed missing polygon bug of cobblestone walls connecting to fences. Connected fences together, even if of different types (this fixes one error, introduces another; nether fences should not join with wood, for example). Proper icons for the "structure block" block type is now shown. Fixed bad placement of mob head facing west (but, no, I have not added heads, it's still the pumpkin). Biome names updated, and a few temperatures updated. On the TODO list: The Windows 32 version crashes on startup; need to fix that so the Mac version can be made. The custom terrain packs are not updated in this version. The "[Block Test World]" is not updated with 1.13 content, nor are Color Schemes. On export, Waterlogging is not fully supported, and 3D prints should translate waterlogged plants to be water. Chests next to each other, not allowed in 1.12.2, will cause odd, faulty exports. Bed colors are ignored. Biomes 40-50 rainfall values are not known. Sea pickles do not have their tendril when in water. Flattened coral fans don't appear to composite correctly. Turtle eggs and sea pickles don't have the exact patterns seen, nor are the right sizes and textures. Conduit does not have the exact textures used. The nether portal should not fill the block. Basic scripting works, but block editing is not tested (and 1.13 blocks need to be documented). These problems are all fixable, but each will take some time and effort.
- Version 6.01, 8/6/2018 - exe, source.
Fixed dead bush bug; grass was getting converted to dead bushes, due to a data value error in nbt.cpp (thanks to Ebrahim Hamama for reporting this).
- Version 6.02, 9/14/2018 - exe, source.
Fixed critical tiny model bug: models with torches were scaled down to a tiny size. Added Sketchfab scripting (thanks, Aur&3acute;lien!), moved to zlib 1.2.11 (sadly, doing so does not fix the 32 bit version's crash on startup in this library).
- Version 6.03, 9/24/2018 - exe, source.
Worked around critical export bug: strange memory corruption from GetSaveFileName() that makes 3D print export not work correctly. "Fixed" by saving value before and restoring it after these calls. Ugh. Brightened grass and leaf color export to more closely match Minecraft; old code multiplied the tile's average green by its grayscale texture, when the brightest green should have been used. If too bright for you, use a color scheme to make the leaf color darker. Fixed furnace, dispenser, dropper, and observer tiles so that their tops perfectly match Minecraft's orientation.
- Version 6.04, 10/10/2018 - exe, source.
Critical fix for 1.13 content: potted cactus and dragon head models were not treated properly, causing bad data interpretation. Fix [Block Test World] to show 1.13 content properly, along with other data fixes in it. Make sea pickle model sealed on the top and add the "tendrils" when in water. Update documentation about how to run under Mac and Linux. Updated custom texture packs and included bed part names in Tilemaker, which has a new minor release, 2.07. 32-bit versions removed entirely.
- Version 6.05, 1/27/2019 - exe, source.
New control: Holding the control key while using the mouse wheel changes the lower height; holding the shift key while using the mouse wheel changes the max. height (this latter mode can be slow and laggy, since the map is regenerated on each click). TileMaker 2.08: work with 8x8 tiles properly, give more information about how to continue when a tile is not a power of two, and avoid crashing when given extremely large tiles. (Thanks to Bear Bear, Raoul, and Felix Brekelmans for reporting these problems and suggesting new features.)
- Version 6.06, 2/17/2019 - exe, source.
Coal ore in 1.13 was getting exported as iron ore, due to a "5" that should have been a "6". Bone blocks imported from 1.13 were not getting an axis direction, due to a missing AXIS_PROP flag. The new schematic format introduced by FAWE crashed Mineways. No support for this new (and quite different than the previous) schematic format, but such files will generate a warning when read. A warning is now generated if 1.13 data is present when exporting a schematic (to the standard, old schematic file format). Properly tiled top of double chests so that level one mipmap looks better (i.e., for distant chests). Made many cppcheck cleanups to code; pass by value changed to pass by reference in world read and map display functions, which should be a bit faster. (Thanks to Maker26 and Hubert Theodore for reporting some of these problems.)
- Version 6.07, 3/8/2019 - exe, source.
Modify reader to handle (pre) 1.14 file format change, namely, that there are now up to 18 horizontal sections and these can have -1 or 16 (out of bounds normally) for the Y value. Now Mineways can properly read pre-1.14 worlds with towers up to the maximum height without crashing. Turn off warning that a directory in the world saves directory is not a world, since some users intermingle world and non-world directories. (Thanks to Justis for reporting the "bad world directory" problem, and Brian Jia for the 1.14 crash repro files.)
- Version 6.08, 5/3/2019 - exe, source.
For power users, especially if you use large texture tiles: added "Texture output" checkboxes to dialog that suppresses the output textures being generated. // Fixed the long-standing bug that OBJ exports for older versions of Cinema 4D would import with the textures applied radially. The problem was that Sketchfab set the OBJ export for rendering to be relative, not absolute, coordinates. For some reason, older versions of Cinema 4D would fail to read these; version R18.057 does not. Fixed by separating Sketchfab export values from the normal rendering export values. // Improved user experience by having autocorrection of the bottom height be off by default for schematics or whenever the user has set the lower depth to 0. Updated LodePNG and modified it to use wide character strings, to fix a crash when terrainExt.png files with extremely large block textures, e.g., 512x512, were read in. Change default for exporting models for Sculpteo to be millimeters, as their default has changed to this from centimeters. Make TileMaker a bit more robust, giving an error if a non-power-of-two or other erroneous tile is found, but skipping the tile instead of aborting. (Thanks to Kevin Niestrat for showing how TileMaker mysteriously failed, to SolarPH for helping solve the Cinema 4D problem and for pointing out the flaw with autocorrection and schematics, and another user for reporting the large-tile problem.)
- Version 7.00, 6/8/2019 - exe, source.
- 1.14.2 support; turtle eggs updated from 1.13's odd texturing to instead match in size, as done in 1.14.
- Finally fully fixed bug where repeating an export would output a relative-coordinate OBJ file instead of the user-chosen format.
- Texture output RGB/A/RGBA now supported in scripting.
- Fix wall signs to be oriented properly.
- Fixed bug in which new blocks were occasionally not exported if near the fringes of the export volume.
- Models read in through "import settings" load faster, by avoiding a redraw caused by the color scheme being set unnecessarily.
- When selecting, if water is detected, Mineways now chooses the lowest non-water block for the lower height.
- The lower height is now renamed to simply "Depth," and "Max height" simply "Height."
- Interpret the "single" chest property introduced in 1.13, so chests next to each other that are singles are shown as such instead of being joined into a double chest.
- Fixed flower sizes and positions for flower pots.
- Set and use waterlogging property for more blocks (slabs, stairs, trapdoors).
- Flowers, grass, and other natural objects are now given a consistent "wobble" in their location in the block, like Minecraft does (but not using the same algorithm as Minecraft, as I do not know their method).
- Chorus plant blocks have added consistent randomness to their shapes.
- Properly connect fences, gates, and walls to one another.
- Properly orient piston head textures.
- Added automatic proper initialization of "sort by block type" system masks for blocks.
- Show on the status line that the model is being imported when read in with "Import Settings."
- If the internal tile texture is used, instead of an explicit TerrainExt.png, no warning is now issued when reading back such exported files with "Import Settings."
- Renamed "Split materials into subtypes" export option to the slightly-less-confusing "Split by block type," and expanded the documentation on this and related options.
- Tilemaker updated with new lodepng library.
- Numerous other fixes throughout.
- Version 7.01, 6/15/2019 - exe, source.
- "Export tiles for textures" option added for Wavefront OBJ export. Now each tile can be exported to a separate texture image, making image substitution simpler and permitting mipmapping to work better. Updated Blender and Cinema 4D instructions.
- Added individual names to output of objects, e.g., instead of "Poppy__1" you will now see "Poppy__Blue_Orchid." Someday I'll take the time to make all these names unique.
- Added Red Sand, Log, and Bubble Column identifier names for mapping and output.
- The "F1" key now opens up the online Mineways reference page in your browser.
- Fixed lectern export: top was being exported twice (added test code to assert if the problem is encountered in the future).
- Fixed lantern and other export for Sketchfab, which was filtering out content unnecessarily.
- Added material names for types of stone and wooden double slabs, to match the single slab names.
- On export, texture coordinates are now labeled with their corresponding Minecraft block texture name.
- Bug fix: For Wavefront OBJ solid color export, export Tr = d - 1.
- Documentation revised, with all shortcuts moved to the Mineways reference page.
- Version 7.02, 6/20/2019 - exe, source.
- Added feature: separate tiles are written to a subdirectory, default name "textures". If no subdirectory is given, the tiles are written to the same directory as the OBJ and MTL file, as before.
- Convert MWO_ chest tiles without cutouts to RGB only, no alpha, as alpha throws off some viewers.
- Fix tab order on export dialog.
- Version 7.03, 7/7/2019 - exe, source.
- Fixed bug where the program crashed when missing blocks were visible when exporting. This had to do with the stack reserve size not being large enough. Along the way I noticed empty chunks were not loading properly, leading to them getting loaded repeatedly. This is fixed, so such areas should be accessed more efficiently now, meaning a bit faster drawing when the view changes.
- Added "-m" to the command line options, which minimizes the Mineways window on startup. This is useful for running Mineways fully automated with scripts.
- Moved lily pad up a small bit (similar to redstone dust) to avoid z-fighting in the obscure case of a waterlogged slab.
- Changed "Cut" and "Smooth Sandstone Slab" to be a correct map color of beige, not red. Similarly fixed (polished) granite and smooth quartz slab map colors. Fixed "Emerald Ore" to not be red. Changed "Smooth Red Sandstone" to have the same map color as "Red Sandstone". Fixed "Sea Pickle" and "Turtle Egg" colors. Dimmed "Bell" color so it doesn't look like a light source. Added colors for some additional slab types: polished andesite, (polished) diorite, end stone brick, and (pure) stone.
- Name fixes, for those who care: Fixed "Tall Grass" blocks to be named "Grass" and "Double Tallgrass" to be "Tall Grass". Fixed "Leaves" to be "Oak Leaves". Fixed (the new) "Sandstone" to properly be named "Smooth Sandstone". Ditto with "Red Sandstone" to "Smooth Red Sandstone". Changed "Snow (layer)" to "Snow" and "Snow" to "Snow Block". Changed "Monster Egg" to "Infested Stone". Brown and red "Mushroom (block)" to "Mushroom Block". Changed "Wooden Slab" to "Oak Slab" since there are sub-type names for all the different types. Changed "Weighted Pressure Plate (Heavy)" to "Heavy Weighted Pressure Plate", and same with "Light". Changed "Large Flowers" to "Sunflower". Changed "Red Nether Brick" to "Red Nether Bricks".
- Added block sub-type names for "Wet Sponge", "Chiseled Sandstone", "Cut Sandstone" (ditto with the Red varieties), "Block of Quartz", and the "Mossy/Cracked/Chiseled Stone Bricks" (ditto with the Infested varieties, plus "Infested Cobblestone").
- Cleaned up documentation a bit, fixing an error on the reference page and improving the text throughout.
- Version 7.04, 8/10/2019 - exe, source.
- Fixed bug where "split by block type" was reporting sub-block names in the OBJ file, but still using numbers in the MTL file.
- Some "manufactured" tiles were not bled along their edges properly, as bleeding occurred too early; also, semi-transparent alphas were ignored. All tiles are now bled to their edges, to make mipmapping work properly.
- Hide blocks 253 and 254, which are special internal IDs, in the [Block Test World] in release builds.
- Instead of a blocks directory, read the *.jar or an unzipped directory structure to get the blocks, chests, bed, end portal, barrier, and anything else directly from the structure. Allow reading in a series of .jars and overlaying (analyze each first to get the maximum resolution needed overall). Then get rid of TerrainBase.png.
- Consider reading in the chest, bed, and other elements (maybe shulker boxes - there are a lot of them, though) as separate textures in a separate zone (say, at the bottom) of the TerrainExt.png file, like in jmc2obj. Also allows direct export of the texture.
- Analyze name of file given on command line. If it's a world level.dat file (or single world directory), load that world. This functionality is easy enough to do by making a script that loads the world, but having the program figure this out would be a nice little usability addition.
- Add glTF export? Use this or, better yet, this.
- Zoom further out, allowing a wider view of the world. The main problems with this idea are that Mineways does not read blocks quickly (it should multithread block reading like the newer version of Minutor does) and that selection becomes a bit imprecise.
- Export all exported model elements to a Mineways script file, so that they can be modified by scripts or text editors and reloaded.
- Use an installer for Mineways, such as INNO, so that vcredist.exe is properly installed. One more level of complication, though.
- Add Pocket Edition/Education Edition support. Right now MCEdit properly reads such files. This turns out to be a bit of work, as the file format (Google's LevelDB) is entirely different than the NBT format used in the Java version of Minecraft. See this page for details. Note that pymclevel, though it's in Python, may help in decoding the Pocket Edition format.
- Extend color schemes to the new tiles with IDs greater than 255. These new IDs are admittedly bogus, but right now there's no way to turn off the output of these newer blocks. That said, color schemes appear to be a feature that's rarely used.
- Add a "Go to location" dialog, where you give a location and the view is centered on it.
- Beds should have separate colors. Or not. These would take up a lot of tiles and kinda overload Mineways...
- Almost out of space for composites. Go to an "on demand" system, noting which tiles are used and outputting only these.
- Try to deal with waterlogged objects better. A waterlogged slab will have a water surface that causes z-fighting on the sides of it.
- TileMaker should handle non-power-of-two tiles, such as found in the BPN--FLOWS texture pack.
- Go to location. Pop up a little dialog for X and Z location you want to go to on the map. Beats scrolling. There's a super-indirect way to do this right now: select an area, export, in the export dialog give the location you want to go, hit OK, then hit F4 to go to that location (or you could write a script: select a block location, then jump to that location).
- Head, sign, and banner support (among others). Realistically, probably just head support, since the others would be a huge amount of work to emulate and could soak up a lot of texture memory.
- Make a version of Tilemaker that runs as a Windows program, both for ease of use and so that it can run on the Mac.
- Zoom out: Some people use Mineways for mapping. Being able to zoom out further has been requested. The downside: more map chunks to read so it might be slow, I'd have to mess with code I don't know well, selection could be funky. My advice is to use Minutor, which has parallelized map chunk reading and is optimized for mapping.
- Biome support: get biome color and use it to change terrain's output color. Currently only the biome at the center of the export is used to set the color of all blocks in the export. The hard part is blending (and saving all the resulting textures, a potentially large number) at biome margins.
- Various blocks could use more support, e.g., pumpkin and melon stems color, farmland wetness. This will use up more texture tiles, but that might be acceptable.
- JSON support. Version 1.8 of Minecraft supports JSON descriptions of block models. Supporting this would make adding new blocks fairly easy, as well as letting users make their own custom block descriptions. That said, it's a lot of work to add this.
- Full "lesser" block merging for 3D printing: right now smaller blocks such as fences are not merged properly with surrounding blocks to make a manifold, watertight mesh. This is done a bit for slabs and stairs and some other cases, by not generating a face if it's fully covered. However, for the most part I'm leaving it up to the 3D printer's software to properly merge these blocks together; I recommend using netfabb's free cloud solution for basic single-color-model cleanup. Some software does poorly with the current geometry, e.g., Sculpteo drops blocks. Adding a robust triangulator and the ability for a block to query its neighbor's face loops would begin to fix this problem. Insanely hard problem, so this is definitely in the "wish" category.
- Work on Mac and Linux: my code is a Windows beast. Currently, Mineways works on Linux under Wine on Linux and the Mac. If someone wanted to make a Qt version of this code, great. The MinewaysMap subdirectory shouldn't need much work, it's just the Win subdirectory that is platform-specific.
- Better color selection: this is a weakness with the original minutor. Yes, you have to put in hexadecimal numbers for the color.
- Vines should work better for 3D printing. When they hang down without anything next to them, they have to be blocks, but when they're adjacent to trunks or other blocks they should go flat. That said, this doesn't look quite right: a vine on a trunk will be flat, but then if it hangs in the air it will fill the "outside" block. I think the answer is to shift the vine inward from whatever block it's in to the one it's touching, but intervening properly is tricky.
- Shulker boxes would be nice to process, as we do with chests.
- Connected textures would give more continuous results for surfaces such as glass and bookshelves. One problem with this idea is that these are custom tiles, so this feature could be added for the default texture set, but not the various other texture packs.
- Integration with Shapeways' API and i.materialise API: Mineways could save each user a few minutes by directly uploading the resulting model files to Shapeways or i.materialise. While manually zipping and uploading is not a big deal, it's a bit of a pain to set the default material, add "Minecraft" as a keyword, and so on. These APIs would set all this information for the user, as is done by MineToys, 3DTin, and TinkerCAD. That said, this option is at the bottom of the list because I think it's the wrong workflow. Normally you want to export from Mineways and then use MeshLab or other program to preview the model to make sure it looks right, then you want to upload. Not checking the model before uploading seems over-optimistic to me in most situations.

Block Types SupportedThere are two main modes of export: for rendering and for 3D printing. These mainly differ in that some blocks, such as flowers, are not things that can be printed as is. For 3D printing, the "Export lesser blocks" option has a major effect on what gets exported. Note that this option is on by default for rendering; turning it off will turn a number of blocks into "full blocks" instead of true geometry, for a more abstract look (but, no one ever turns it off). Finally, for the "lesser blocks" option there's a "fatten" suboption, which makes fences, fence gates, doors, free-standing sign posts, and pressure plates thicker, so they're more likely to print without snapping off.
If you want to test particular blocks to see what they look like, use the "[Block Test World]" and the block IDs to select and export whatever block types in whatever mode you want. Alternately, you could find a texture test world you like, such as this one.
Here's what Mineways exports as of version 5.01:
Mineways does not support export of characters, creatures, sign text, paintings, or banner patterns.
All "full blocks" (stone, dirt, wood, on and on) export the same under all modes. The table below outlines the rest. "Flatten" means a billboard, such as a flower, or small object, such as a torch or lever, is flattened to be a decal on the block below, since such objects are too thin to be 3D printed.
