polygroups become pieces

I have a ZBrush object with 2 polygroups. When I export them as an OBJ from ZBrush, the object comes into Blender as two pieces.

Is this normal ZB to Blender behavior? Not exactly what I want.


edit: I do not have this problem using GoZ tho.

Fixed it. You have to have “Grp” turned OFF.
