Minecraft / Mineways

    Mineways is a free, open-source program for exporting Minecraft models for 3D printing or rendering, including Sketchfab.

    See also Eric Haines' official Mineways to Sketchfab documentation.

    1. Open your Minecraft World: File → Open World

    Upload Publish 3d model minecraft mineways Sketchfab

    Optionally, you can choose a new terrain file instead of using the default. File → Set Terrain File.

    Upload Publish 3d model minecraft mineways Sketchfab

    2. Select an area of your world (Right-click + drag) and go to File → Publish to Sketchfab.

    3. Enter your API Token, model title, description, tags, and mark it as Private or Draft as necessary.

    Upload Publish 3d model minecraft mineways Sketchfab

    4. Click Upload!

    Processing 

    During the model processing, we do lots of things on our end to make the model look great.

    • Generate Ambient Occlusion to give corners and interiors those nice shadows
    • Set all textures to Nearest filtering to preserve the blocky Minecraft look
    • Set all materials to Single-sided to help with some transparent blocks like water
    • Adjust PBR factors to make the materials look correct (roughness, etc.)
    • Use Alpha Masking for trees to preserve blocky look and avoid draw order problems
    • Adds 1% emission to maintain correct brightness after AO is added
    • Adds "sunlight" to make nice lighting

    The result:

      I have a few updates to these instructions, as Mineways 4.14 makes things simpler still:

      1. File ? Open World - yes, do this

      2. File ? Set Terrain File - you don't need to do this, the default terrain file is built-in; you can change this file if you wish to.

      3. Navigate to your terrain file and click Open. - ditto, ignore this step.

      4. Select an area of your world and go to File ? Export for Rendering.

      5. Name your file and choose Wavefront, OBJ.

      6. Choose your export options and click OK. See the Mineways Documentation for details. - I recommend you choose the "Create a ZIP file..." checkbox near the upper left. Then you can simply upload this ZIP to Sketchfab.

      7. You will now have 4 files to upload to Sketchfab: *.obj, *.mtl, and two textures (*.png). - ... and the ZIP. 8. For best results, go to Settings ? 3D Settings ? Materials tab ? Transparency. Switch to Alpha Masking and set the texture Format to Luminance. - you no longer need to do this, as Mineways has been improved to work better with Sketchfab.

      Heh, looked better on my screen - I guess the comment software removes all line breaks. Anyway, you may want to update your page here, and you could also grab a new screenshot of the export dialog, the only piece that changed a bit in Mineways 4.14. Not critical, but I wanted to let you know.

      @erich - Thanks! I made these changes, including the export dialog image (you can see I upgraded to El Capitan since then...)

      And yes, Zendesk has been giving me some issues with Markdown and line breaks recently. Interestingly, the "Edit" comment dialog is more robust and respects line breaks. I've fixed your comment :)

      Nice edits! Good to show the Terrain option that way. I'm also glad the Mac version works for you - a very few users are having some hard-to-debug-from-a-distance problems I can't reproduce. There's one little bug: you should get five files, not four: three PNG files, including one called "minecraft-world-RGB.png" - this one's used by fully opaque surfaces.

      Actually, I use wine to run the 32-bit Windows version. I gave up on the Mac version, but I'll give it another go sometime.

      Strange, I just tried again and I don't get that file - is it a known bug or something you just noticed from my screenshot?

      Huh, might be a bug! Or I may just be forgetting something I do... Could you send me a zip of the OBJ, MTL, and textures produced? Or put them on Sketchfab somewhere to download? I'd like to make sure I didn't mess up somewhere.

      @ctk08 - I'm sorry about that. Looks like it's a known issue on the Mineways end. There are some workarounds here:
