There are some breast motion morphs in one of the FBM packages posted at the Free Site.  I've been trying to use magnets for that effect, but it's difficult to position the mag zones to affect only the intended areas.  Bones or body handles for breast motion might work better with weight mapping for more controlled deformations.  Any of these approaches should be able to be animated using Ockham's Jiggles script.

There are also some breast sizing morphs in the Free Site FBM sets.  I don't think there are really any shaping morphs which can create the wide variety of different possible shapes.  Although Les has contributed some nipple morphs.  :laugh:

It has been suggested that breast shaping is somehow one of the most important points for character individuation on a base figure.  Whether that's true or not, I could see a shaping package being popular.  :laugh:

Cage can be an opinionated jerk who posts without thinking.  He apologizes for this.  He's honestly not trying to be a turkeyhead.

Cage had some freebies, compatible with Poser 11 and below.  His Python scripts were saved at archive.org, along with the rest of the Morphography site, where they were hosted.
