oh... another thing that needs to be dissected is the michael 2 long arms/legs/neck body dials. they're not morphs, they're scale controls, and they seem to use propagating scale to make the limbs longer, but still work properly. i read on victoria's tech notes that the long limb dials keep the joint centers centered, and that seems to be the only way to do it. i know you cant get the joint center trans values to slave to a dial and change, because i tried that. :/ well, i can see in the m2 cr2 that the stretch dials control the x-scale of the arms, and that the arms are not using propagating scale for that. so i dunno how they are working it. the stretch arms seems not to distort the hands/fingers... ah, they're not stretching the hands. okay... but the fingers, at least, should bend very wonkily, being pushed so far away from their previous centers.
