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.
Bug:Tying a toolstrigger brush to this entity will result in the entity being rendered in-game as a raw brush of said material, unless VBSP was compiled with -nodrawtriggers. It should be set to Nodraw or Invisible instead. Code Fix:In the spawn function, set rendermode to kRenderTransTexture (2) like its counterpart, or better yet, set EF_NODRAW. The bubbles themselves are sent to clients using temporary entities, so they will still be rendered.Note:Used bubble sprite: sprites/bubble.vmtNote: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
