Actually this is not a new issue.. This is actually something left over from p5 if you remember the problem with Neftis hair and someone discovered if you regrouped it it worked fine. check out the OBJ it's fragmented. This can be seen in a lot of OBJ's. I actually figured it out with Will Dupree about a month or so ago. if you regroup the object it solves the problem. however regrouping it can also cause other problems. So.. P6 is actually showing it more but it's not a new issue
