destructibles system :D:D

if anybody is using ue5, be careful of the chaos destruction system, there are LOTS of pitfalls, the real destruction is obviously bad for perf, but even the cache one is bad also, I have to do quite a bit of modification, for some reason Tim decided that after the cached destruction finished playing, it will still keep ticking for all the props, so if you have large amount of destroyed props, it will fuck the perf bad.
