Does anyone know how to make the hip joint look realistic in these types of poses? Or is this problem merely one of Posers many limitations? Thanks!

If you can't afford Vickie then I suggest you get Eve 3 from Traveler's Morph World, just make sure you get the older version of Eve as well as you will need the .obj you'll get from that to modify it into Eve 3. She is split up differently in the hip and chest area and is a big improvement over Posette. (link to Morph World is on the right) Alternately you can get a new version of Nene, Nene Lite here: http://www.eurus.dti.ne.jp/~masasi/PROGRAM/PAE.html I think she has better joints. And yes, it is a limitation of Poser.
