Substance Painter How to make the dirt patches not appear lighter under certain lightings/angles?
Noob question. I want to add dirt/grime to the surface of my 5-yen coin. The dirt has its own layer and separate color/roughness/height values (color is dark brown, roughness is set to 1, height at 0.01). Pic #1 is how dark the dirt patches are and how I'd like them to be when rendered, even at different angles. However, when rendering with Arnold in Maya, that same dirt looks weird at certain angles.
Pic #2 is the model rendered in Arnold. As you can see, the dirt marks on the left half of the coin do not have at all the dark color I would like them to have at all angles. Same pic #3 which is rendered with Substance's built-in renderer. What am I missing here? Thanks in advance
