I'm trying to do some test with your "blend material" master material. In the attached screenshot you can see an instance I've created. As your blend material works with displacement map from quixel surfaces (quixel old) I was expecting the ORD slot. Where to load AO and Displacement textures? EDIT: the roughness channel is the ORD? I've opened the material instance created with Dash tools and it seems to be there, right?
