    How would I go about making a character look like it is blowing soap bubbles? This does not have to be realistic for it is going to be added to a flat character (think southpark). What I specifically concern is when the bubble pops and the way a bubble has that oily rainbow fluctuating.
    I have trapcode particular. I’m thinking this might be key.
    Thanks for any help or pointers to tutorials.

    Play with the decay time for the particles and the random seed. Not a user of Particular, does it have the ability to use an imported image as the particle? Like a pre-made bubble with the rainbow sheen on it?

    If the rate of bubbles is low, you could also make one perfect bubble in photoshop or from a real photo, and loop it with keyframing in AE or other compositor to make as many scaled iterations as you need.

    Apply Effects>>Simulation>>Foam to a solid layer and that will give you bubbles. From there it’s pretty much the same as a particle generator. Change the view in the Effects Control window to “Rendered” and bring down the production rate quite a bit. Around 0.05 will give you a few bubbles and you can adjust the physics accordingly.
