Hey Gang,
I watched the “intro to ZBrush 3” by Ryan Kingslien, and when he extracted a shirt from the model he was able to select the interior surface of the new shirt subtool and delete those interior faces to reduce his polygon count. I watched him do it, so I know it’s possible, but he didn’t explain what keys he was holding down and how he automatically selected all of the interior surface. If anyone can tell me how to do this I would greatly appreciate it.
Thanks.
Ctrl+Shift+Click on an interior vertex. The interior polys will be a different polygroup than the edges or exterior, which means that everything except the interior will be hidden. Now invert visibility by Ctrl+Shift+Dragging on an empty part of the canvas. You can now use Tool>Geometry>Delete Hidden to remove the interior polys completely.
Aurick,
My extraction is all one polygroup. It doesn’t have any separation between the interior and exterior. I tried auto-grouping, but that didn’t do anything either. I’m running on a mac. Is this a known issue?

Which version are you running? I’ve just done tests with 3.2 and I do get separate polygroups. They sometimes appear to be very similar colors, but the procedure I described above works just fine.
Ok, I just realized what I did wrong. I had imported this subtool from an earlier version of the model and forgot I did it. When I went to the earlier version it still had the polygroups.
Thanks again Aurick. You rock this forum!
