How do I setup a rooftop line of sight area? The end result I'm looking for is a player goes on a roof and can look down onto the streets. If they're on the streets they can't see onto roofs. Bonus if being on one roof lets you see onto other buildings/roofs. I tried using the terrain, but it results in players seeing onto the roof even from street level, but not behind it. If I double layer it, they can see on the roof, but not down into the streets.
