Procedural mesh does not get sliced

Hi! I’m trying to slice a procedural mesh in vr using a projectile, but my mesh doesn’t get sliced when i hit it. Blueprints seemed to work fine when I tested it on the procedural mesh of a simple cube, but when it comes to my actual mesh (which has pretty complex geometry) slicing doesn’t work. I’ve tried it with “use complex as simple collision” both turned on and off, with collision presets set to “BlockAll” for the procedural mesh, but projectile still does not affect my mesh. I’m pretty new to ue4 and don’t know much about collision. Any ideas?
