Zoom and Universe Size controls for the Foam effect

Adjust the following controls to specify the zoom and universe size:

Zoom

Zooms in or out around the center of the bubble universe. To create really large bubbles, increase the Zoom value instead of the Size value because large bubble sizes can be unstable.

Universe Size

Sets the boundaries of the bubble universe. When bubbles completely leave the universe, they pop and are gone forever. By default, the universe is the size of the layer. Values greater than 1 create a universe that stretches beyond the borders of the layer. Use higher values to make bubbles flow in from off-screen, or make it possible to zoom out and bring them back into the picture. Using a value lower than 1 clips the bubbles before they reach the edge of the layer. For example, when you want to confine bubbles to a specific area, such as inside a mask shape, set Universe Size a little larger than the mask size to remove all the extra bubbles and speed up the rendering process.
