This kind of hammered lookDisplacement in Rhino 5 - YouTube ) as a better way. Might there be a better way to accomplish something so fractal with more control then Heightfield? Maybe with Grasshopper? If yes, can someone point me to the right components?
This isn’t playing to Rhino’s strengths, so I guess the question is “Why do you want to do it in Rhino?” FWIW Zbrush or 3dcoat, for example, would be better tools for this.
