I'm making a Brick Wall texture, from the Rob Tutyel course. The main problem with this wall is the Sandstone border. It's just bulging way too much.
I've learned why this problem occurs. I'm using a mask maps to tell Blender where and where not do the Brick Wall displacement. For the part where it isn't supposed to do displacement, it just over does it. I don't know if there is some sort of "null" node. But sure as hell sounds useful right now.
I am aware that the plaster is using the Brick Wall displacement. I was trying to solve one of them, because they are both basically the same thing.
