Please see the attached Blender file, where I have 3 cubes, each parented to a unique bone - I cant seem to be able to export this setup into USD and have it translated correctly - can you kindly review and advise please?
That’s a limitation of the current exporter-- USDSkel rigid bindings aren’t yet supported. The current version of the exporter is intended to be used with skinned meshes only, so you’ll have to apply Armature modifiers to the meshes in question and weight them 100% to the target bones.
