Producer controls for the Foam effect

Adjust the following Producer controls to specify the location from where the bubbles originate, as well as the speed at which the bubbles are generated:

Producer Point

Positions the ellipse from which all your bubbles appear. This "point" can be much larger than a point. In fact it can cover the entire screen. Producer Point defines the center of the area from which the bubbles can be produced.

Producer X Size, Producer Y Size

Adjust the width and height of the Producer.

Producer Orientation

Adjusts the rotation or "orientation" of the Producer. Producer Orientation has no noticeable effect when Producer X Size and Producer Y Size are identical.

Zoom Producer Point

Specifies whether the producer point and all of its associated keyframes remain relative to the universe (selected) or to the screen (deselected) when you zoom in or out on it. For example, if you set a position for Producer Point in the upper left corner of the layer and then zoom out on that layer, the producer point stays in the upper left corner of the screen if you don't select Zoom Producer Point. If you select Zoom Producer Point, the point moves with the universe as it is zoomed, and it ends up closer to the center of the screen.

Production Rate

Determines the rate at which bubbles are generated. This control does not affect the number of bubbles per frame. Rather, the rate is the average number of bubbles generated every 30th of a second. Higher numbers yield more bubbles.

If a large number of bubbles appear in the same point at the same time, some may pop. If you want a lot of foam, increase the values for Producer X Size and Producer Y Size so that the bubbles don't immediately pop each other.
