As the purpose of the smoothScale channels is to improve the appearance of the actor when its neighbour is scaled, and as they seem to be having the opposite effect in this case, perhaps the smoothScale channels relating to the thighs should be deleted from the hip2.

I'll consider that. Thanks for hunting down that bug!

Did you remove the corresponding channels in the thigh actors, as well, or only the ones in hip?
