The link is an excellent resource for shaping. Though the comments are disturbing.

Is there a way now, or in the new version of poser (thinking with that joint moving functionality with morphing), a way that could auto pose breasts to deal with gravity? Like with bones and IK? And can that be modified to react properly with say a bra, though it's of course only there in idea?

A side question, has anyone thought of breast morphs that simulate the shape of different bras, for dynamic simulations?
