is there a way to do a clown pass by part and not by material assigned? (i have a very heave part count model and was rendering out some very basic color layouts, but now i want to do some post processing in photoshop and break it up by parts. It would take forever to unlink each material from each part)
OK, never-mind. Looks like if you unlink material at the top level, it will break up every part into individual shaders too.... that should fix the problem
Otherwise you can use the render layer and put some parts on different layer?!
You said perfectly, this way you can do it. Thanks for your query.
You can check the photoshop tutorial on youtube. Thanks for your post.
