# .fbx files

**.fbx file: Filmbox 3D Scene**

The standard interchange format for 3D models with rigging, animation and materials.

- **Windows:** Blender, Autodesk FBX Review, Unity

## What a .fbx file is

FBX is Autodesk's format for moving whole 3D scenes — meshes, skeletons, animation, cameras and lights — between Maya, 3ds Max, Unity and Unreal. It exists in both binary and ASCII variants, and version mismatches between exporter and importer are the usual reason a file fails to load. Blender imports and exports it natively, and Autodesk publishes a free FBX Review viewer.

## Converting it

A .fbx file is commonly converted to .obj, .gltf, .stl, .blend or .usdz. It is a binary format, so a text editor will show unreadable characters rather than its contents.
