I red many posts on this topic , but I am not sure I have found an analogue to my problem. Generally , the body physics are working fine, and until now I haven't encountered a single problem. But recently , when the main character is naked, her breast and but are acting weird , some kind of a glitch . Mostly it's about a constant hopping of the body parts (breast , butt) , and then, the breast is stretching away to much, when it is touched during a pose. And it all comes back to normal when I put some clothes on her. Other naked characters do not have this problem. The BODY is UNPB with breast and butt collision . I have already reinstalled and updated the mods concerning this matter , but nothing helped . Any ideas, please!
