I have a OBJ that I am importing into Blender 2.5x (using options Object, PolyGroups and -X90).  I have created a Box UV for it in UV Mapper, and it shows if I go to edit mode, select all, and go to the UV Image/Editor view.

Whats odd, is that I can find no seams on the OBJ in Edit Mode. 

So, instead, I went ahead made sure to select all, and "Clear Seams" and retry the UV Unwrap. 

After the operation was complete (in Edit Mode) I switched back to the UV view, and there is a different "cut-up" of the suit!?  I would expect it to be all l one piece.

Any thoughts about the OBJ import, and how it may be figuring out how to "cut up" my suit OBJ?My guess is that it is breaking it up per the grouping (i.e. Import setting for Polygroups) that I used, since there seems to be a Neck unwrap that looks similar to that group?  I dont find anything that says it unwraps by group by default.

In fact, I already had did this and added seams, and it seemed to combine the cuts?  Maybe there is a "how it unwraps" setting I am missing?  I will keep looking, but wanted to ask.

My goal is to start anew, place seams and unwrap.
