Thanks Teyon

I see what your getting at. If you started from say, a cube in ZB then there would be no point in UVs but with a decent base mesh then the displacement would be a sort of 3d sub divide.

I'm using metasequoia which although straight forward does bones, animation and now has sculpting tools (or will have for general release very soon). I've tried swapping to blender but its just not working for me.
