how do i get my Projectile to ignore Owner ?

First post and it’s not a bad one. The problem with Instigator (AFAIK) is that it’s of type Pawn. Best to do what you’re suggesting with SpawnActor’s Owner parameter. Not sure why I didn’t think of it before but it works nicely.

For anyone who needs specifics: Pass in “reference to Self” to the “Owner” pin of “Spawn Actor From Class” when you spawn your projectile. The owner should be the weapon actor. Then in your “On Component Hit” event, first thing you do is a Branch that checks if “Other Actor” is NOT equivalent to the output of a “Get Owner” node. If true, then handle the collision. If false, then it collided with its own weapon so ignore it. (Should’ve just done screenshots, oh well)
