This effect works with 8-bpc color.
Original image (left); the Cell Pattern effect creates a displacement map (center), which is used as a displacement map for the Displacement Map
effect (right).
Cell Pattern The cell pattern to use. HQ denotes high-quality patterns that render with more definition than their unmarked counterparts. Mixed
Crystals is available only as a high-quality option.
Note: The Static Plates option is identical in appearance to the Plates option. However, when evolving, the static plates retain a uniform lightness
value, whereas the plates shift the lightness of the cell pattern.
Invert Inverts the cell pattern. Black areas become white, and white areas become black.
Contrast/Sharpness Specifies the contrast of the cell pattern when you use the Bubbles, Crystals, Pillow, Mixed Crystals, or Tubular cell pattern.
The control specifies sharpness for any of the Plate or Crystallize options.
Note: The option chosen from the Overflow menu affects the contrast.
Overflow How the effect remaps values that fall outside the grayscale range of 0-255. Overflow isn’t available if sharpness-based cell patterns are
chosen.
Clip Values above 255 are mapped to 255. Values below 0 are mapped to 0. Contrast amount controls how much of the image falls
outside the range 0-255; higher contrast amounts result in a mostly black or white image, with less gray. Therefore, less subtle cellular
detail appears at higher contrast settings.
Soft Clamp Remaps grayscale values to fall inside the 0–255 range. Contrast appears reduced; cells are mostly gray with few areas of
pure black or white.
Wrap Back Values above 255 or below 0 are reflected back into the 0-255 range. For example, a value of 258 (255+3) is reflected to 252
(255-3), and a value of
-
3 is reflected to 3. With this setting, Contrast values above 100 increase complexity and detail.
Disperse 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.
Size The size of the cells. The default size is 60.
Offset Determines the portion of the fractal shape used to create the pattern.
Tiling Options 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.
Evolution 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 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.
Cycle Evolution Creates a loop that forces the Evolution state to return to its starting point.
Cycle 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.
Random Seed 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.
Anchor The point of origin of the checkerboard pattern. Moving this point offsets the pattern.
Size From How the dimensions of the rectangles are determined:
Corner Point The dimensions of each rectangle are the dimensions of the rectangle with opposite corners defined by the Anchor and
Corner points.
Width Slider The height and width of a rectangle are equal to the Width value, meaning that the rectangles are squares.
Width & Height Sliders The height of a rectangle is equal to the Height value. The width of a rectangle is equal to the Width value.
Feather Thickness of the edge feather within the checkerboard pattern.
