Why convert USD to FBX?
People convert usd to .fbx because game engines like Unity and older DCC pipelines still expect FBX for rigged, animated and skinned assets. FBX is the long-standing interchange format for meshes plus skeletons and animation, which many tools ingest more reliably than USD.
How to convert USD to FBX
Blender FREE
Import with File > Import > Universal Scene Description, then File > Export > FBX (.fbx), choosing options like Selected Objects, Apply Transform and Animation as needed.

Open .FBX details →Quality & what to watch
- USD composition arcs (references, payloads, variants, instancing) are flattened; the FBX is a single baked hierarchy.
- USD/MaterialX shading is reduced to FBX's basic material model, so PBR materials often need rebuilding in the target tool.
- Skeletal animation transfers only if the USD uses UsdSkel and the exporter maps it cleanly; verify rigs and skin weights after export.
