Hi

I have a problem where when I convert my mesh from Subdiv to Nurbs it breaks apart

I imported the piece from Zbrush, made sure that any group info was turned off so that it was a solid piece

Converted Polygon to Subdiv successfully, but when I try to convert Subdiv to Nurbs it breaks apart like in the image shown.

I tried to use the Attach Surfaces and Attach Without Moving feature but that didn't help anything

Anybody have any ideas what I can try to ensure it stays as one solid piece after conversion

Any help is greatly appreciated
