Is "generate overlap events" expensive?
Hello! For my top-down game I am trying to create a system so that when the character goes inside a room, whatever is between the pawn and the camera becomes opaque. The way I am having this happen is by creating a component that contains the function to make it opaque, and having a collision volume between the player and the camera. So when the player overlaps the scene component, it'll make it invisible.
This means that in order for it to work, I have to enable "generate overlap events" on every actor that I want to become invisible, which leads to my question: Is "generate overlap events" expensive to have ticked on many actors? Or is it not that big of a deal?

Hi there, i guess this is pretty relative compared to your alternatives.
I would suggest to take an actor, configure it and duplicate a decent amount of them in your level. (just a few alt+drag when selecting a whole duplicated bunch over again). If your profiler doesn't burn, i guess you should be good :)
This is what i did with the Menger-Sponge fractal: Over 6000 actors, all of them with overlap events, and ingame there are about 20 pawns speeding around on the surface where every pawn overlaps with about 4 of them. No issue at all.
