What are Clip brushes and when should I use them?
Clip brushes are often used to keep a player from getting stuck along a wall, floor or ceiling by any brushes that protrude from those surfaces. For example a light fixture or a column. There are two methods for using Clip brushes: • • Create a triangle and put it flush with the sides of the protruding object and another side on the wall. This allows the player to be “moved out” slightly when moving along the wall. • Create a rectangle Clip brush that covers the whole length of the wall and is out far enough to cover the edges of the items sticking out of the wall. Both methods were used in the original Id levels. Using Clip brushes is strongly recommended for multiplayer maps.
