Env bubbles

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

Template:Base brush 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.

In code, it is represented by theCBubblingclass, defined in theeffects.cppfile.

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.  [todo tested in ?]

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