This would be useful for making cloth sim very performant.
Self collisions, self intersections, even CCD if you’re bold… these things are relatively cheap for ONE actor. But for a hundred, you’ll lose all your frame budget, and that’s if they’re simple!
Now, if we could put those settings on a per-LOD basis, or change them at runtime for other kinds of perf-saving systems like actor pooling, they could be turned on only when actually needed! Best of both worlds.
