I made some fracture meshes with 90 cell site count… when I fracture some of them, my perfect particle system goes nonperfect… stops colliding with anywhere… I have my particle collision to every type of collision object… (worldstatic,worlddynamic…)
I just realized that fracture mesh drops my fps, and when the “drop detail” box ticked… my particle stops colliding… just needed to uncheck that drop detail box in the actor collide in particle…
