This is an animation of Victoria 4 with bouncing boobs. The rendering is ok considering the fact that I have it on the preview mode. I still don't know how to keep surface collisions from happing, but the jiggling boobs is what people care more about on these simulated large breast!
If Jessica Alba had a boob job, she might look the girl in this animation. I'm still trying to figure out how to make Jessica's boobs bounce by themselve, but I haven't had any luck. I'm using poser 8 to modify the Alyson character in the face room to make her look like Jessica Alba. The render time was around 3 hours for this animation. I thought about using Maya 10, or Cinema 4D, but why re-invent the boob, when I can just use Poser.
I wish James Cameron would have made Neytiri Boobs bigger. He did this interview on Playboy and made it sound like there was going to be some boob jiggling physics action in the Avatar movie, but there was absolutely no boob physics action. The motion capture did everything except animate her breasts. To make up for what he did not provide us 3D Stereoscopic boob fans. I have made my own version.
