How randomly the pattern is drawn. Lower values cause more uniform or gridlike cell patterns.
note: If you set the Disperse value above 1.0, set the layer to Best quality to avoid artifacts.
The size of the cells. The default size is 60.
Determines the portion of the fractal shape used to create the pattern.
Choose Enable Tiling to create a pattern built of repeating tiles. Cells Horizontal and Cells Vertical determine how many cells wide
and how many cells high each tile is.
Animating this setting results in changes of the pattern over time.
note: Although the Evolution value is set in units called revolutions, it’s important to realize that these revolutions are progressive. The Evolution
state continues to progress infinitely at each new value. Use the Cycle Evolution option to return the Evolution setting to its original state at each
revolution.
Evolution Options provide controls that render the effect for one short cycle and then loop it for the duration of your clip. Use
these controls to pre-render cell pattern elements into loops, and thus speed up rendering time.
Creates a loop that forces the Evolution state to return to its starting point.
The number of revolutions of the Evolution setting that the cell pattern cycles through before it repeats. The amount of time
between Evolution keyframes determines the timing of the Evolution cycles.
note: The Cycle control affects only the state of the cell pattern, not geometrics or other controls, so you can get different results with
different Size or Offset settings.
Specifies a value from which to generate the cell pattern. Animating this property results in flashing from one cell pattern to
another (within the same cell pattern type), which is not usually the result that you want. For smooth transition of the cell pattern, animate
the Evolution property.
note: Create new cell pattern animations by reusing previously created Evolution cycles and changing only the Random Seed value. Using
a new Random Seed value alters the cell pattern without disturbing the Evolution animation.
Checkerboard effect
The Checkerboard effect creates a checkerboard pattern of rectangles, half of which are transparent.
This effect works with 8-bpc color.
The point of origin of the checkerboard pattern. Moving this point offsets the pattern.
How the dimensions of the rectangles are determined:
The dimensions of each rectangle are the dimensions of the rectangle with opposite corners defined by the Anchor and
Corner points.
The height and width of a rectangle are equal to the Width value, meaning that the rectangles are squares.
The height of a rectangle is equal to the Height value. The width of a rectangle is equal to the Width value.
Thickness of the edge feather within the checkerboard pattern.
The color of the nontransparent rectangles.
