I've been following this with interest, but I can't seem to implement the basic idea under discussion.  When I've added an extra parent for the Hip, it simply behaves like a secondary Body actor.  The result is somewhat like parenting the figure to a prop or something.  It helps me with extra figure rotation options, but hasn't changed any bending results.

On the other hand, I work almost exclusively with Vicky 1 (I never even graduated to Vicky 2 LOL).  Would that make a difference and effectively nullify the benefits?  Is it essential that a figure be re-cut to implement this technique?  If so, what pronciples are applied when recutting?

And... (hopeful) you (phantom3D) state that you've adapted this rigging for various figures.  You haven't perhaps re-rigged Vicky 1?  A better rig for the figure (and instructions for porting clothes to the new rig, if necessary) is something I, personally, would pay cash money for....

Keep up the fantastic work!  :D
