Why convert BBMODEL to FBX?
A .bbmodel only opens in Blockbench, so people export to .fbx to bring models, textures and animations into game engines like Unity and Unreal, where FBX is the standard interchange format.
How to convert BBMODEL to FBX
Autodesk FBX Converter FREE
Blockbench only writes ASCII FBX; if you need Blender, run the exported .fbx through Autodesk FBX Converter to turn it into binary FBX first.
About these formats
.BBMODEL
Blockbench 3D Model Project
A .bbmodel file is the native project file of Blockbench, a free 3D model editor used mainly for Minecraft and other low-poly game models. It is a JSON text file that stores the geometry,…

Autodesk FBX (Filmbox) 3D Interchange File
An FBX file is a 3D model/scene in Autodesk's Filmbox interchange format, carrying geometry, textures, rigs, animation, cameras and lights. To view one free, use Autodesk FBX Review or…
Open .FBX details →Quality & what to watch
- Blockbench exports ASCII FBX only; Blender imports binary FBX, so a direct import fails until you convert the file.
- For a Blender workflow, glTF is usually the smoother choice and avoids the ASCII/binary FBX conversion step entirely.
- Pixel-art textures may import with smooth filtering - switch the engine's texture filter to point/nearest to keep them crisp.
Frequently asked questions
Why won't Blender open my Blockbench FBX?
Blockbench writes ASCII FBX and Blender only reads binary FBX. Convert it with Autodesk FBX Converter, or export glTF instead.
Does FBX keep animations?
Yes, FBX carries animations and embedded textures and supports all the important model features for engines.
Which engines accept the FBX directly?
Unity and Unreal Engine import Blockbench's FBX natively without any conversion.
Is there a better format for Blender?
Yes - export glTF/GLB from Blockbench, which Blender imports directly and with better material fidelity.
