Perhaps I should clarify. By joint magnets I mean the inner MatSphere and outer MatSphere. I understood that they work in the same way as the Mag Zone of a magnet. In any case what I meant was that the joint controlling thing (that which determines how the verts around the joint center move when the joint dial "Bend" is used) seems to be acting on the morphed object (joint correction morph) in a different way to the way in which it acts on the original BentKneeObject. Which is of course logical since at least some of the verts are in different positions.
