Quote -  i just did a quick  test in p8 and it worked better than before, the autogroup is no use still, but there was less tearing and strange un-moveing poly's, mabe a map of correct areas to group is about somewhere.

The auto grouper is rubbish imo.  I haven't used it for anything since my very first attempts to rig anything.  If you get into the habit of planning where the bones will be as you make a model, and you use edge-looping modeling techniques, then it is usually much less difficult to make your groups by hand in the modeler if you take advantage of things like loop selection and fill selection (most modelers can do this).

You should also save the figure to the Figures library and re-load it into a blank scene after you leave the Setup room.  When you first import your model into Poser, it will be all one "solid" welded piece of geometry; when you take it into the Setup room and add bones, and then go back to the Pose room, the geometry gets split up and becomes un-welded, so when you test the bending of various joints, the mesh will show "cracks".  When you save the figure to the Figures library, a number of "weld" statements are written into the CR2 but these won't actually be run until you re-load the figure.  After you re-load it, the weld statements get executed and the figure's mesh is all one piece again, like it was before you imported it.
