env_bubbles in game, with density set to 6 and frequency set to 2.

env_bubbles is a brush entity available in all Source games. It is used to create a volume in which to spawn rising bubbles. The number and frequency of bubbles can be adjusted.

env_bubbles is obviously intended for use in water, but it can be used outside of water if such an effect is desired.

Note:Tying a toolstrigger brush to this entity will result in the entity being rendered in-game as a raw brush of said material. It should be set to Nodraw or Invisible instead.

Bug:Doesn't work in Portal 2 with any tool texture.

Confirm:May be a HammerAddons bug caused by the origin not being set to 0 0 0.
