I am not concerned that the pelvis area is not the top actor in the hierarchy.

I am concerned that the pelvis area has been named "hip2" and therefore makes it very difficult to provide Wardrobe Wizard support.

Previously there have been other figures where the creator has not understood the implications of deviating from Poser standards. In some of those cases I have worked with the author, reconfigured the model and sent them back a copy which they then distributed from their site. As in this case all that was involved was a search and replace on the body part names. I believe one had used "rShoulder" rather than the Poser standard of "rShldr". No big deal, easily fixed.

If required I'll be happy to do the same here but please let us not get side tracked into hierarchy and IK pros and cons, they simply are not relevant to getting the figure Wardrobe Wizard compatible.
