I've not noticed any issues using Michelle with GoZ and ZBrush.

Not that I necessarily would, I guess. Maybe I just didn't use the smooth brush on her. Or maybe GoZ manages the weld... somehow?

But it is Michelle I've been practising with in ZBrush, mostly, so far... and making FBMs for her...

...and, my thinking is, if she was good enough for Blackhearted to sculpt... and I don't think he was complaining about her ZBrush compatibility? Assuming he'd have been using that?
