That said, its main reason for existence here is that it's the only file format that Shapeways uses for colored models. 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. Export options 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 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. Create files themselves: the exported files themselves are also made available for previewing.

This is done because too often the. Material Export Remember that for any format you can turn off a block from being output and being visible by setting its alpha to zero in your own color scheme.

On the left of the dialog are texture options: "Export no materials" option is just that. The color scheme's colors controls these. Rarely used or useful, but gives a different look. This option requires the terrainExt. 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.

This option creates many more textures, but can be considerably faster since not all textures are exported. These textures are similar to Minecraft's block textures, though possibly modified to improve how alpha cutouts look.

This mode allows you to later modify and swap individual textures in other applications such as Blender. It also is a better option for exporting high resolution texture resource packs where the block faces are x or larger , as having a single, large texture as generated by the other options above can be too large for systems such as Blender.

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. Finally, if you make a zip and do not check "create files themselves," the PNG texture files will not be deleted, since they may be shared by other exports. Content is shown on the left exported with "all textures to three large images" and on the right with "individual textures.

The "texture output" export option can save you much time if you are exporting again and again while using a large custom terrainExt file see the next paragraph for what that 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 "individual textures" option, you need to uncheck all boxes to turn off texture creation and export - any one box checked means all textures will be output.

The other major option for texture export is "Export individual textures", just below the "full color texture patterns" option on the export dialog.

As noted in the previous section, this exports a texture for every block face used in the mesh produced. The "texture export" checkboxes below can also be used to suppress textures when using it. All three checkboxes must be unchecked to stop texture export for this option.

Also, since the "export individual" method truly exports only those textures needed, if you change the boundaries of your export, you may expose new blocks but won't export their textures if you turn off texture output in other words, suppressing texture export is then not a good idea. That said, used properly, turning off texture output can save you time each time you export a model.

Custom Terrain The one file you may want to change is the terrainExt. To select a different terrainExt. PNG file on to Mineways. In either case, at the very top of the Mineways program you'll see what terrain file is active, right after the name of the world you've opened. Mineways supports a number of premade terrainExt. Visit the Textures page for previews and download links for terrain files not included in the Mineways distribution.

If you have a terrain png file you would always like to use by default, copy it into the directory where mineways. If you know how to use the command line , you can also use a command line option to specify the terrain file to use on startup, e.

Yet another way is to use a Mineways script to change the terrain file. This is handy for exporting the same model multiple times, each time with a different terrain file applied. For a more thorough explanation of textures and how they're used in Mineways, read the Textures page.

To make terrainExt. Fine details are unlikely to be visible, though sometimes I'm surprised to see them. On the left, the basic x terrainExt. You can download high-resolution versions of terrainExt. In Mineways do "File Choose Terrain File" and select either; the higher-resolution version gives sharper results, at the cost of memory.

You can also interactively compare these sampling methods here vs. These textures are for the default Minecraft appearance. To avoid blur for your own terrainExt. 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. There is a case where you'll want your textures to be blurry: when they're far in the distance.

Usually mipmapping is done by a renderer to make this happen. The Minecraft block textures are normally put in one large texture and each is given a border 1 pixel wide. This border avoids bilinear interpolation artifacts. However, mipmapping for extremely far blocks will not work well, since block textures are next to each other in this big texture.

The solution is to either "Export individual textures" where each block face is exported to its own texture , or disable mipmapping for rendering and live with the artifacts other sampling techniques should work fine.

Wavefront OBJ has two concepts when it comes to polygon faces: named objects and named groups. In Mineways there can be one or more objects in a scene, each object can have zero, one, or more groups inside of it. Normally there is just one object exported; the "Make groups objects" creates a separate object which then contains a corresponding group.

Mineways has rough "block families. Each block in this family has a separate "type. Any number of polygons can be in an object or group. There is also a set of materials defined in the.

One and only one material is applied to each polygon. Export separate types: on by default, this option says each type of block - stone, logs, fences, and so on - are put in a separate group. Turning this option off means no groups are created, which can be useful for simplifying import into rendering packages but can make editing more difficult. 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. By checking this box, all of 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. You may also want to check the Make groups objects option, e. For Blender you'll also want to make sure "Material per family" is checked. Note that the individual blocks option will change the appearance of some blocks, such as water and glass blocks, as all faces now have sides, which are visible.

Normally Minecraft removes these interior sides e. Material per family: on by default; blocks in a family or type; see next option have their own material. If turned off, 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 easier to edit: move, delete, etc.

Split by block type : Blocks have a family and a type. When checked the default , the individual types are used for grouping and materials. If you find you are editing too many materials, turn it off and materials will be exported per family.

You can see many of the families on this page , e. New materials are limited to those where there's a physical difference in the material itself, not just geometric changes. For example, 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 separate materials for its 16 levels of power, even though Mineways itself differentiates only between off and on states.

Campfires, sea pickles, and respawn anchors will be given separate emission levels when this box is checked; else the maximum light level is assumed.

Confused yet? There are non-obvious interactions among the various settings. A table follows, describing the results when using this 2x3 set of blocks - two grass blocks, two stone, two diorite - as the exported volume. Recall that diorite is part of the stone family. Each block family has a separate material. Each block type has a separate material. Single material. Result is 22 visible block faces. When exporting individual textures these settings have slightly different meanings, because separate materials are created depending on the texture needed, not the Minecraft block family or type.

Similarly, if neither "Export separate types" nor "Export individual blocks" is on, materials are output as needed, since there can be no "single material for all" with "individual textures. Make groups objects: By default, the OBJ file produced has just one object, consisting of everything exported.

If you want to make each group into its own separate object, which can be useful if you are trying to export individual blocks and animate them in the scene, check this box. This is useful in Blender, for example. Custom material Checking this box causes a more elaborate illumination model to be output. By default it is checked, so that a more elaborate material model is used.

This hints to G3D to make the textures look blocky, giving the classic Minecraft look. This line should not hurt OBJ readers, which should simply ignore it or possibly flag a warning. If you are using a physically based terrain set , the custom material will also include additional channels of information, such as textures for normal maps, shininess power, metallic, and emission textures.

These attempt to follow this proposed specification , also documented here. You may also find that the corresponding color texture is a better choice for the emissive texture in particular, if supported - this is true for the G3D viewer. Currently Mineways has no switch to use these colored textures instead. For USDA export, the Custom material setting mainly has the effects of making the texture's texels appear blocky, in Minecraft fashion, and present stripped down materials in Omniverse Create.

This is almost always a good idea, even with high resolution textures. If you turn this option off, you can get texture wrapping problems, where the bottom of a fire cutout, for example, will get interpolated along the top edge of the fire, giving a narrow line of fire at the top of the cutout.

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.

This option was on by default for rendering up to version 5. Create composite option off the default. The ladders, rails, and lily pad float a bit above the surface. Create composite option on. Note how the ladders, rails, and lily pad are attached to the surface. 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 bit version of Mineways, which is what runs on the Mac.

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 rest of the options mostly have to do with 3D printing, which follows. Exporting to 3D print As 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 also has a help section. 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 degrees to have it face south and so display better on your models page.

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. 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. Key tip: if you look at the export file Mineways creates for you 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.

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. By default, it is set to show the approximate cost of a print for 1. 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. 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. 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. Share and embed 3D models anywhere online.

The goal of this step will be to create a low-poly version of our model using automatic mesh decimation. Now, we need to give it the high-poly mesh as input. We can now select the MeshDecimate node and adjust parameters to fit our needs, for example, by setting a maximum vertex count to , By default, the graph will become read-only as soon as a computation is started in order to avoid any modification that would compromise the planned processes.

Each node that produces 3D media point cloud or mesh can be visualized in the 3D viewer by simply double-clicking on it. Double-Click on a node to visualize it in the 3D viewer. Making a variation of the original, high-poly mesh is only the first step to creating a tailored 3D model.

Right Click on the Texturing node Duplicate. Right Click on the connection MeshFiltering. By doing so, we set up a texturing process that will use the result of the decimation as input geometry. We can now adjust the Texturing parameters if needed, and start the computation. External retopology and custom UVs This setup can also be used to reproject textures on a mesh that has been modified outside Meshroom e. The only constraint is to stay in the same 3D space as the original reconstruction and therefore not change the scale or orientation.
