Like bouncy boobs? Like, really bouncy boobs? Want something more exaggerated and unrealistic than the vanilla boob jiggle (which is also just as nice)?
Using mr_reeh's breast collision and physics mod (not required) I added very bouncy and exaggerated physics to all bodies + gear that use breast (mune) bones in TBSE-based bodies, including:
The collision is based around your character's wrist bones, which can lead to some... interesting effects with larger chests when crossing/folding the arms in animations.
If you want less jiggle/intensity, you can check out mork's jiggle mod.
