Details:
● The system should recognize and assign the correct textures for each material when a USD file is reloaded inside Unreal.

How would you imagine the implementation of the enhancemenent?

This seems tightly coupled to Unreal which I'm not too familiar with. I'm happy to brainstorm along but likely this is better assigned to someone else. If this is full USD API then of course I'd be happy to jump in if I know what's needed. :)

Ayon does not have usd loader implemented yet.
We need to have more info on what to do before starting this ticket to import USD info as the client requested. Does it mean only merging the identical material slot which just needs the asset loader to do so, or it requires something even more complicated which touches the USD material bindings?

The USD import(Asset Import) option is like the screenshot below. (good reference if they just want the asset loader).

Also if we have implemented the usd import for layout and it is probably using USDStageActor to spawn actor, there is option to set material purpose which is material purbose to use when parsing USD material bindings, applying updated material purpose which may be the client
