Sorry about the vague title. Here’s my issue: I imported an OBJ, split it into polygroups based on previously set-up UV tiles, divided the model 3 times, then ctrl-shift clicked the head to isolate it and went to work. After sculpting on it for about an hour, I exported an OBJ to open in Max and realized that it had more polys than when I exported it and that there were a bunch of triangles around the base of the neck.
After going back into Zbrush to check things out, I noticed that when dialed down to the lowest subdivision level that the head group of the model (the group I was working on) appears to have one more level of division than the rest of the model (see image). I have no idea how this happened and am hopeful that there is a way to correct it.
Is it possible to divide just an isolated polygroup?
