I have a character that is linked into a Scene as a collection. I want to change an input value of a nodegroup in one of the character's materials, preferably without making the whole thing local. Of course, I cannot access the materials of a linked collection in the usual way.
I am looking for the best way to Override or proxy or whatever else I need to do in order to get access to the material. And I'm going to need to be able to do this to every material in the scene, of which there are many (but I can write a script to mass apply whatever method.) I'm just trying to avoid having to make it all local because then my files will be multiple gigs in size.
Is there a way to do this?
