Bigger boobs merging into each other

[Bourbon321]

So when I've got a model with bigger boobs they sometimes go into each other and I'm not sure how to fix it
It's like they merge together instead of push up against each other and it really ruins the imersion
How to fix plz?

You could try turning ON "breast hard coliders" in the breast physics 2 tab in person. Some model creators turn those off to get a nice natural saggy look, but if affects collision.
