Unfortunately a bug with Poser 7 slipped through testing.
We've got 5 people running into trouble with LBs in their Poser 7. Massive deformation around the hip and thigh area and we can't seem to explain why. There are others that have less issues, but it seems that the major issue is the SymShag Pussy opening. The rest seems to work.
Someone said: inject the V4 with IK off and the figure entirely zero'ed, even the morphs. What you can also try is to run the python, then open a new scene and load the new figure manually from the library and then run the injection, entirely zero'ed.
Any Poser 7 user out there without these issues? Please please please send us an email. Would you perhaps know something?
We're busy trying to figure it out as we speak. In the meanwhile, if you have Poser 7, I would wait with buying it.
