Towards the bottom of the effect, you'll see a Flow Map area.
This section allows you to use a gradient layer to control how the
bubbles fl ow. A fl ow map can restrict bubbles from going to cer-
tain areas. For more information on using maps to control effect
properties, check out Chapter 23.
Pound for pound, the Rendering settings are perhaps the most
important in the Foam effect. These parameters determine what
