Hi all,
I am not sure how to achieve this with Corona, actually not even in C4D.
I would like to combine 3 bump shaders for example: some scratching together with some dirt and some brushstrokes as if it was real paint.
I am guessing something along the Layer shader? I tested a bit and did not get the result I was looking for. Maybe multiply mode is not the way to go?
Another idea I had was to create 2 separate materials and then combine them both with a mask? Is that possible in Corona? For example, have a metal material, a paint material, and a mas of scratches, the result will look as if the paint has been scratched and you can see the metal underneath. I could use this logic to stack bump shaders too.
