I have just UV unwrapped my model and I will be editing its texture in Photoshop but it's hard to tell where each things are and I have to do a lot of trial and error. I know you can generate a grid texture as well (Color Grid and UV Grid) which is more helpful but still not what I have in mind.
What I want is to generate a texture where each face is colored differently to help me figure out exactly what is what in my image editor. Does blender have a feature to do it automatically?
Thanks
