"In Poser's dialect of .OBJ language, e.g. the line g lForearm Arm Body_ means that the following faces are in group lForearm AND in group Arm AND in group Body_" Ya know, for years now, I've been interpreting the above type line to mean some form of pseudo sub-group (so most of my programs don't handle this in a Poser-consistent manner, btw). But from some recent work, I see that Poser does seem to allow for polygons to belong to more than one group. I guess I should re-read the .obj file spec again, but I was always under the impression that that wasn't possible. Either way, to handle these files, I'll need to go back and re-work some code paths... . It's interesting that Poser duplicates the polys though... that would seem to me to cause some rendering artifacts (which I can't say that I've noticed).
