I'm in the final stages (I hope) of a new map. The map can be described as two large rooms separated by a porous wall. Thee is a base in each room (it's mainly a CTF map). The walls, floors, and ceilings of these maps are very detailed - lots of sniper ledges, hiding places, and generic bumpy stuff. There are a couple of places where one can see from one end of the map to the other through the bases and the wall.
How should the hint brushes be placed to have the best effect?
