After spending nearly a day with trying to update to 1.2 I have to say that there seems to be an issue concerning Auto Setup Plugin:
I was using 1.11 before and in order to get 1.20 to work at all, I had to delete all the cache folders in the project root directory (Saved, Intermediate, DerivedDataCache).
Before doing this it would not create material instances on import and create new materials for everything while not basing it on any master shader which looked quite terrible.
After applying aforementioned fix, the shader instancing started working again, but now the linking of base color maps to the material instances does not work (except for the eyes).
So I end up with a white character with normals, SSS and everything set up except for the base color maps.
The maps themselves are getting imported properly but the texture slots in the shader instances are not activated nor filled with anything.
So there seems to be a slight issue with the Auto Setup plugin, as when imported to Blender the base color maps link just fine.
Am I the only one experiencing this?
Adding the basecolor maps by hand of course is doable, but not exactly within the definition of "Auto Setup"
