Need Help With Basic Animating PEC & BUTT Bone using Avastar Add On In Blender

[Kvko]

So I'm an up and coming creator here on secondlife. I've been looking all over to find a overall better explanation on how to "activate" these collision bones in blender in order to freely move them around or add physics to them for basic, twerk or simple breast touching movements. Ive tried extending these volume bones, I've tried baking. I'm not sure which steps to take to stay consistant with results. If there is a better program please let me know or if you know exactly how to do these it would be great to be either directed to a forum explained down below
