Setting up collision

Hey guys!

I need one object to have no collision with anything, but to generate overlap events (OnActorBeginOverlap event will trigger). If i set “NoCollision” preset, the event doesn´t trigger. If i set “OverlapAll” preset, it works, but moving like objects (like bullets) still collide (bounce off, and i need them to fly through/trigger overlap). I have tried everything in custom collision as well. Could you help me out?

I have had this problem too actually, haven’t tried in the 4.11 preview but do triggers still automatically block projectiles?
