Fogvolume.png

fog_volume is a brush entity present in all games since L4d.pngLeft 4 Dead. It controls fog and other visual cinematic elements within its volume.

Tip: Typically when Valve uses this entity, they have a master version of their FX entities (use the Master flag) which is used for the outdoors effects, then only create fog_volumes for indoors areas.

Note: In Asw.png, the origin of a player is not used to decide which volume they're in, but rather a point roughly 512 units above them. Due to this, the brush has to be extended far up above the level.

Note: The entity uses its bounding box to detect players, meaning the trigger will always be in a cuboid shape regardless of how the brush(es) look.
