Attached Link: The Sound of Your Laughter

There was a script out there called "Dynachest," but it doesn't work in Poser Pro 2012. (Bad magic number)  Roogna's "jiggles" script works, with questionable results.  When I do animations, I make heavy use of Ironman 13's squish tools and "Natural Bounce."  You can see the effects here:

(The last animation, beginning at 2:25, was not easily done and I struggled to make the body movements sync with the piano.)

 

But, it's not just a woman's bosom that would be nice to have for soft body dynamics.  Even still renders, where one character is holding another--like the attached link, above, would look more realistic.
