Ok i have been using the boobsetting plugin and the breast are still stiff as a rock during sex,,,wth am I doing wrong??
I had the opposite issue with them flopping wildly, turns out I turned the 'softness' setting way too high on accident, so maybe try that, but do light tweaks cause it gets out of hand fast if you put it too high lol
I don´t use the boobsettings any more, I found especially on bigger breasts the collision behavior becomes uncontrollable and causes weird deformation.
I prefer softer boobs with noticable jiggle, so I rework most cards with "Softness" to 100 - 150 and "Weight" to 20 - 50. For higher weight you have to reduce softness to avoid too saggy tits. Boob settings is deactivated!
For my observation more softness results in more movement in Hscene rather than more weight.
But the movement seems to depend more on the animation script itself than normal physical law - so the same breast setting sometimes is more static and in the next scene very bouncy.
If you still prefer boob settings I found this recommendation from its author, maybe it helps you
