func_dustcloud is a brush entity available in all Source games. It spawns randomly-sized dust particles within its volume.

Bug:In  : Particles may disappear in opened portals at some angles. More serious glitches may occur in other specific scenarios.  [todo tested in ?]

Tip:This entity is affected by env_wind.

Note:The default material is particle/sparkles.vmt. It is normally extremely low-res, so consider overriding this .vmt for improved appearance.

Note:This entity is functionally identical to func_dustmotes except that the size of sprites created by this entity will scale realistically depending on the viewing distance, and ones created by func_dustmotes will always take up the same amount of screen space regardless of viewing distance.
