Advanced Jiggle Physics R&D #1 (Patreon)

Super super rough animation lol, it's just 2 poses interpolated. But here is some progress on a jiggle physics technique that I'm trying to develop. I feel like it's rare to see breasts in 3D animation deforming based on the torso's rotation relative to the direction of gravity, so I'm trying to set up a system that would allow me to do that in Blender. It's only applied to her left breast currently as I'm still in the testing phase.

Most guides that I can find online for jiggle physics mainly focus on jiggle bones that don't give the artist enough control over the shape and movement of the breast. So I'm trying a different method I've been thinking about. I'm not sure if it will work yet and it's a bit time consuming to set up, but so far the results look promising!
