Sorry, BT, rereading my post I don't think I was clear that I'm stuck in the poser part of the tutorial. What I meant to say is that I've done the "File->Export->Wavefront OBJ..." bit then the "Select "Single Frame" part but it's at that point, whilst I'm still in poser, that I can't find the "Export object groups for each body part" option. and I'm still stuck :(
