trying to get my projectile and secondary projectile to ignore each other but still collide with anything else. I’m relatively new to BP so not sure how to solve my problem.
In your projectile blueprint. Thee you have usually a sphere colission or something else. Set this in details panel under colission to projectile. Under customize set it to ignore projectiles. Then the projectiles should ignore each other. You can create your one colission channels in the projects settings too.
