Original post:
When I isolate a polygroup and hit ‘crease’ it will not crease the border of the polygroup correctly. Instead it creases the border and then randomly creases across the polygroup. This is destroying my workflow in creating jackets, hero masks, bracers, etc.
Resolved:
I just found the ‘cTolerance’ slider to the right of ‘crease’. If I slide the tolerance to the right all the way (180) my creasing is isolated to the polygroup edges (when other polygroups are hidden). Problem solved.
