Does anyone know a way you could take a displacement like a high noise variation PF of spike like thingies, and equalize the heights? I want to plateau them, and use them for icebergs, including the "roots" disappearing into the volume of the water, however, I have some spikes that don't even reach the water level and look bizarre showing under the surface, and I really don't want to spend time examining miles of terrain to mask hundreds out.
