Add USD Referencing to Blender

Blender’s USD support is good, but adding USD referencing could make it a lot better. With referencing, you could link external USD files instead of importing them, keeping scenes lighter and better organized.

This would:

Let you work with external assets without cluttering your file.

Load only what you need, improving scene performance.

Make it easier to manage complex projects with modular setups.

Allow tweaks like moving objects or changing materials without altering the original files.

It would make workflows inside Blender way smoother, especially for bigger projects.
