Damage prevention channel does not work


I have made a shield actor for blocking any projectile from dealing damage to my player character, and all projectiles that can deal radial damage have their damage prevention channel set to ECC_Visibility. Yet my character was still damaged by radial damage when I was play-testing it.

I didn’t work with radial damage, but I assume it used a sphere overlap, not traces. So it will affect anything it overlaps with, no matter if its behind an obstacle.
