I'm having trouble with displacement. I'm trying to follow the instructions here to get the procedural pitting I have from the material on to the mesh itself so I can export it as an .stl for 3D printing. As shown below, I've tried using the displacement node to no effect. I've also tried using the displacement modifier, but in that case I'm not sure how to pipe in the material.
I've also tried the instructions here, but no dice with that process--too much stuff has moved since then. Any help for a noob would be greatly appreciated!
