AI Perception (sight) not seeing actor

No, that’s going to be something you script yourself using blueprints or a behavior tree. I have never heard of using AI perception in that way. Unless I’m mistaken it was an improvement on “pawn sensing” and that was as the name implies an ability to “sense” other pawns in the world. AI perception improved upon that back end code and added more features and customizability but I don’t think what you’re looking for is going to be handled by AI perception
