How can I trace camera's field of view area?

“WasActorRecentlyRendered” does a nice job too, but sometimes it is not that precise. For example, It gets “true” when I’m staying with my back close to the actor, or when I’m staying front close, but looking straight down.

Tbh, I’m just trying to recreate these “if looked at by player camera” events from Layers Of Fear, so I’m experimenting with different methods to choose one that will get it closest to the original. There HAS to be a way, as LoF 2 was made on Unreal. :slight_smile:
