Displacement and Bump map control Is there a way to control where the displacement bump map does and does not affect. Would using the weight paint brush be good? The displacement bump map is made procedurally generated with texture coordinates, noise texture and a displacement map. I followed this tutorial made by Blender Guru. https://www.youtube.com/watch?v=Rh5gAQLtOls&amp;t=456s
You can plug a map into the Scale input of the Displacement node.  You may want to do some math on the values as they go in.
I don't think weight paint is available through cycles nodes, but you should be able to use Dynamic Paint a la this answer.
