Hello,
Ive been having this problem with zbrush and it can be quite irritating. It seems that zbrush wants to sculpt straight through objects. The tools sculpt the front and backsides of objects. No w this seems to be based on the size of the brush and proximity of the two sides of the mesh.
Im sculpting a belt. I need to put threading in the belt. For some reason zbrush has sculpted the backside also. How do I make zbrush only sculpt the polys that my cursor is on and ignore the backside? I have attached a pic. Notice how the threads indented on the back and popped out on the front. This is so annoying. How do I fix it?
