If I have a 3D procedural texture that I like as a displacement, but I want to use a 2D texture map to flatten the displacement in areas, can I do this?

I think maybe not, since displacements are not local to layers, but are instead global to the entire material, but I thought I'd ask the experts.

Nope, not unless there is a adjustable clip feature which allows you to clip displacement past a certain colourvalue. Say it clips just below 32,32,32 in the darker parts of the procedural map and 200,200,200 in the brighter parts of the map. Those clipped parts should render flat as the clipped colours will create a planar displaced surface once rendered.

But i don't think Maxwell has that feature yet, so the short answer is probably no.

Does the RGB clamp work with procedurals?
