Just wondering if its possible to map texture channels to specific shader inputs. I am aware of the ORM map, but if you say wanted to pack the textures differently is it possible to remap them? I was looking through the API but couldn’t see a way to access the channels of a texture.
A custom shader would work I believe, but from I can see it may need a rewrite of the PBR implementation and how it handles each channel.
Is this the correct assumption to make?
