Is it potentially because my root object for my projectile is not the capsule or the mesh? I tried doing a test where I re-created a similar setup on a new object with no DefaultSceneRoot component, and it seems to be doing better, though I haven’t controlled for all of the variables.
My only problem with this is that I’m inheriting from a base actor class that I hoped to have provide some extra functionality, so it would be a pain if I had to create a new class and duplicate this functionality just to get the SceneRootComponent to go away.
