Why convert USD to OBJ?
People convert usd to .obj when they just need static geometry that virtually every 3D and CAD tool can open, for 3D printing prep, quick reference or single-frame exchange. OBJ is an old but universal mesh format with the widest tool support.
How to convert USD to OBJ
Blender FREE
Import the USD, then File > Export > Wavefront (.obj), optionally enabling the .mtl material file and applying transforms.

- Only basic
