That could be a big part of it... the P4 instead of Vicky issue... Vicky & Michael have buttock body parts, and the P4 people don't... Just for more background info... how are you trying to pose her? Are you just moving the thigh body parts? If so, try moving the buttocks too, especially once you get the thigh bending pretty far... shrug I'm not an expert, but I try to think about how a real human body moves, and recreate it with the poser figure... for example... with shins... your shins do not go side to side... well maybe a little bit if you put enough pressure on it, but not like Vicky's can... and your hand doesn't really twist, it's your forearm... just things like that... Hope that helps (though I kind don't think it did). K-
