How do I get a projectile to _completely_ ignore another of it's class?

I have some projectiles I’m spawning but they keep colliding with each other. I don’t want that. I really need them to pass through each other and generate no hit event. Hit events for my projectiles make them self destruct so I need them to completely ignore them. Can anyone clue me in?

You can try to cast in your hit event to your projectile with “other actor” from the hit event as object for the cast, if it succeeds you hit an projectile, else you hit something else.

Thanks. That was the first thing I tried. It still makes the projectile halt mid-air
