MOSSBACK STUDIOHow to convert an FBX to a bbmodel
- Press Open a model and pick the .fbx file, or drop it on the page. If its textures are separate picture files, pick them together with it (hold Ctrl).
- Press Download .bbmodel.
- In Blockbench: File > Open Model. The textures are already inside the file.
- Size: FBX files count in centimetres. With 1 block = 1 unit ticked, 100 FBX units (one metre) become one block. If the model comes out far too big or small, untick it and open the file again, or scale it in Blockbench.
- Textures: pictures stored inside the FBX are used. If the status line says a texture was not found, pick the picture files together with the .fbx.
- Binary FBX from version 7.0 on and text FBX are read. Very old FBX 6 files are not; save them again from Blender or Autodesk's converter first.
What comes over from another 3D file
- Kept: every mesh with its faces and UV mapping, the object tree as Blockbench groups with their pivots, the textures (stored inside the .bbmodel), and plain material colours as small colour textures.
- Not kept yet: animations and skin weights (a rigged model comes in its rest pose), vertex colours, normal and roughness maps.
- The result is a generic Blockbench model made of meshes, not cubes. It is right for editing, painting and exporting to game engines. Minecraft Java block and item models need cubes, so those have to be rebuilt by hand.
- Faces come over as triangles. Models above about 20,000 faces get slow in Blockbench; lower the detail in your 3D program first.
I checked the files by opening them in Blockbench 5.2 itself: same meshes, faces, vertices and textures as the tool wrote.
Something missing that you need, animations for example? Tell me, requests decide what I add next.
Other formats
- bbmodel to GLB / glTF: one file with textures and animations.
- bbmodel to OBJ: for programs that do not read glTF.
- bbmodel to PNG: a picture of the model, or its textures.
- GLB / glTF to bbmodel: open a glTF model in Blockbench.
- OBJ to bbmodel: an OBJ with its textures as a Blockbench project.
- MagicaVoxel to Blockbench: a .vox file as cubes.
- Also read: .dae (Collada), .stl and .ply. Open them on any of these pages and press Download .bbmodel.
- Writing FBX: not done here. Save as GLB, open it in Blender (File > Import > glTF 2.0) and export FBX from there.
- Minecraft JSON (Java block / item models, Bedrock geometry): that is Blockbench's own job, File > Export in Blockbench. This page is for getting a model out to other programs.
