Re: Diet Coke Bubbles. Trippy Style

The one tip I can tell you about Foam is, look down the list for a property called "Flow Map". This will use any black & white (grayscale) image as a "ramp" the bubbles roll down. (if you make it in AE, Pre-comp it)

White is high ground, black is low ground, shades of gray are the ramp. The bubbles move away from or avoid entirely white ares. You can even give the bubbles "tunnels" to follow. Just create a maze with white for the walls and black for the path you want the bubbles to follow. Make the path light gray fading to black to guarantee they flow the direction you want. It's fun to play with.

Hope this helps
