I was experimenting to solve some problems with the breast and tried to create two more body parts, rNipple and lNipple parented to the chest.
The preliminary results were amazing even I did only the joint parameters of xrot with the Rnipple and I am nothing skilled with joint parameters and deformers.
With only xrot, yrot and scales you can control the full dynamics of each breast and things that cannot be done with magnets.
There are two problems, the first one is that the existent breast morphs will not work anymore, problem that can be solved with some software for automatic morph conversion.
The second problem is tragic and sad, I cannot share my results!
As I am modifying an existent original figure geometry creating two new groups, due copyrights I cannot share the modifyed geometry neither any encoder will work because it doesn't store the modifications that I created. The only thing that I can share are the images created using a "new" Vicky.
Anyway is an excellent idea for the figure makers to be worked out  whith the creation of new figures.
No pictures to show yet, I need some weeks of work, maybe less, depending on the available time that I have.

Stupidity also evolves!
