I haven’t tried yet because I’m afraid of screwing up my ZBrush 4 license. I still have ZBrush 3.5 R3 on my computer and I was wondering if it can still be run. Now I understand that you probably can’t have both running at the same time, but can you still run one or the other without screwing something up?
The reason I ask is, if one or more of my old ztools, for whatever reason, can’t be opened in ZBrush 4, then I can export them as an .obj out of 3.5 R3 then import into ZBrush 4.
