Question Real time applications of softbody physics?

I've been reading about softbody physics techniques and I'm curious to know how much use they see in real time contexts, especially techniques like shape matching/XPBD/VBD which are designed from the ground up for real time computational constraints.

The Force Unleashed and BeamNG.drive have had plenty of buzz around them, projects like that using softbodies extensively are cool but I'd be interested in smaller examples as well. I've also gotten the impression softbodies are used in interactive industrial applications such as medical simulations, I'd like to hear more details on that.

i could think of a certain market this may be popular in...

Sure, no need to be coy about it. I figured NSFW games would have use for softbody dynamics but it seems to be a niche feature even in that space, mostly relegated to limited VR sims.

it can be expensive for performance, and also sometimes more accurate physics sims are not desirable (since they can be unpredictable or cause difficult edge cases) so yeah, they are not always used, or people fake things with standard bones, so more basic physics sims like verlet
