BubblerB.oo.ma is a non-dynamic geometry based bubble generator which is used to mimic a large mass of moving bubbles in a straight line or a curve. It's created using a fluid containter which generates a mesh. You can control the speed, size, frequency and resolution of the bubbles through the main control object called CTL. This asset also has a mental ray shader. You can control the length and angle of the bubble mass using the three smaller control objects, which in turn drive a 3 point arc. The bubble mesh is attached to that arc. Please note that sometimes you'll have top shuffle frames to see changes in settings - it's an artifact of fluid to polygons.
When conbined, the two assets can be used to create underwater bubble effects like trails, bubble explosions, or aquarium type effects. I've left the inner workings mostly unlocked, but hidden. You can access all the guts of the rig by selecting the CTL object, tapping UP to go to CTL GP and switching "Guts" on.
Please send any questions, bugs or feature requests to me in the comments section, and if you like the bubbler, please give a hearty thumbs up to your local neighborhood fluid simulator.
