I'm trying to create an emergency light (one of those lights that allow beams out on two sides only and rotate). I've got the case rotating using a func_rotating and a light entity is inside it providing the light.
My problem is that the light comes out all sides, not just the holes in the case. Does my case need to be bigger (it's 14w x 14l x 13h now) or is there another way to fix my problem?
