soft body makes body jiggle far too much

I should start by saying my project is pornographic. I’m an adult artist who wants to extend into 3d.

My problem is this. I’ve modeled a female body with very excessive endowments. I’ve rigged most of my body so far. Her breasts are rigged with IK’s to allow easy posing of her breasts. Due to their size, I do not expect any amount of programming on Blender’s part would be able to handle all of their movement correctly.

What I want to do is add jiggle to their movement. I want to animate the body normally, but have the breasts automatically have their own jiggle as she moves. . Attempts to manually animate a jiggle effect have been time consuming and displeasing. I’m hoping that there’s a way to animating a jiggle effect to these bones.

I’ve tried using the soft body physics, but the effect is FAR too intense. If I move the model at walking speed, all effected parts of her body come alive and bounce at least 15 feet back and forth and up and down. I’m not expecting the simulation to control the entire thing, just add some jiggle to the mesh while I control the larger movement for turning around and such.

I can’t help but feel their may be a ragdoll solution to this, but I have no idea how to make that work. Is there any way I had add “jiggle” bones? I feel that would probably work best. I did look around the forum and couldn’t find anything with this problem. The 2 threads I found either didn’t quite address this issue, or were talking about much smaller breasts so as to be non applicable to my issue.

My ultimate goal is to create some animations with this model, and with future models.

Here is my character. She is clothed, but is extremely buxom.

Can anyone help me with this? I’m hoping this is the right place to put this. I’m also not finding the rules concerning what I am and am not allowed to link, so I very much hope these images are not over the line.

Not sure if it will work, but maybe it’s worth a try: http://www.youtube.com/watch?v=e1lHca7I3So

You don’t necessarily need to have bones in the breasts for this soft body technique to work.

Also, you may want to give her spine bones some extra support (just kidding – I really like your character).
