@SoUlFaThEr: no, actually an entity wearing the FL_WORLDBRUSH flag is an entity that is static all along the game (such as unbreakable glass). You don't "set" an entity to wear this flag explicitly, you do so when you make an entity with no breakable/movable/pushable/triggerable properties. Such as a func_wall for example...
