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

env_bubbles is a brush entity available in all Source 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.pngNote: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.
Note.pngNote:Used bubble sprite: sprites/bubble.vmt
Note.pngNote:In order to make it work in Portal 2 Portal 2 , the bubble sprite material (sprites/bubble.vmt) and texture (sprites/bubble.vtf) must be located in the /material/sprites folder and the TeamSpen's Hammer Addons installed, or at least its portal2.fgd located in the /Portal 2/bin folder.

Keyvalues
