What I mean is, we provide a low poly skeletal mesh collision proxy with its own version of morph targets that we create, and it obtains its animation and morph values from the Master Pose Component from a master skeleton (we’re doing this with skeletal mesh clothing e.g. for animation and morphs). I realize it’s less efficient to do this because collision math vs. spheres has some shortcuts but the advantage for us is that say, you have a guy wearing a robe, and you then morph the guy to be very fat - the physics asset will not change to reflect that, so his robe will clip into his fat areas. APEX has the same limitation. If we could provide a custom collision proxy then we could have the fat guy wearing a robe. The transition between the zero state and the morphed state would probably need time to simulate but that’s OK, we can probably just hide the character/clothing meshes for some reasonable time to allow for that and then make them visible.

e: While we’re fine just creating a full low poly proxy ourselves, maybe a simple alternative would be to collide against a lower LOD (higher number, lower detail) version of the base mesh. (if Simplygon works vs. rigged meshes, which I have no idea if it does)

This is certainly doable, but it needs to be implemented. It would essentially be per-poly collision which would certainly give the desired results! I don’t have this on my update schedule yet, so I cannot give you any ETAs. If you’re up for implementing this yourself, I’m more than happy to assist anywhere I can! In addition to this collision resolution there would also need to be a bit of logic to impart velocity of the colliding body onto the colliding particles which would refine the look/results during fast movement. I do have this feature on my schedule to be implemented.

Hope that was of some help, let me know if you have any further questions!
