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.

Note:Used bubble sprite: sprites/bubble.vmt

Note:In order to make it work in

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

Bubble density (density) <integer>: Bubble Count in Volume.

Bubble frequency (frequency) <integer>: Bubble emission frequency, in bubbles per second.

Speed of Current (current) <integer>: The speed of the water current in the volume, used to move the bubbles.

Inputs

Activate: Activates the bubbles.

Deactivate: Deactivates the bubbles.

Toggle: Toggles the bubbles on and off.

SetDensity <integerRedirectInput/integer>: Sets the bubble density.

SetFrequency <integerRedirectInput/integer>: Sets bubble emission rate in bubbles per second.

SetCurrent <integerRedirectInput/integer>: Sets current speed in inches per second.
