Please take a look a the attached image.
I would like to create a kind of ‘layer’ in the PBR diffuse channel where I can switch out several textures.
I have additional ‘layer’ textures (1a and 1b) that I want to switch and make them part of the diffuse channel using the masks, by somehow joining them into the base diffuse texture.
Is this possible, and if so, what would be the best way to do it?
For me it doesn’t matter if the layer-texture is ‘stamped/baked’ into the base texture, because I can always start over with a fresh base texture and do the stamping again.
Thank you for any advice!
(By the way, this is a very simple example, the actual application uses hundreds of textures, and we cannot generate all possible combinations upfront.)
