I'm very new to zbrush (literally got it today) I started with zspheres, added mesh to it and converted it for sculpting. I sculpted a whole torso but now I want to add legs and a head to the same mesh, how do I add more zspheres w/out going back to the original bad mesh paint job...lol I'm not even sure if that makes sense, anyway please help me out, I'm having issues lol
