Effects and transitions
Cell Pattern effect
The Cell Pattern effect generates cellular patterns based on cellular noise. Use it to create static or moving background
textures and patterns. The patterns can be used in turn as textured mattes, as transition maps, or as a source for
displacement maps.
Original image (left); Cell Pattern effect creates a displacement map (center), which is used for the Displacement Map effect (right).
The cell pattern to use. HQ denotes high-quality patterns that render with more definition than their
Cell Pattern
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.
Inverts the cell pattern. Black areas become white, and white areas become black.
Invert
Specifies the contrast of the cell pattern when you use the Bubbles, Crystals, Pillow, Mixed
Contrast/Sharpness
Crystals, or Tubular cell pattern. The control specifies sharpness for any of the Plate or Crystallize options.
Note: The contrast is affected by the option chosen in the Overflow menu.
How the effect remaps values that fall outside the grayscale range of 0-255. Overflow isn't available if
Overflow
sharpness-based cell patterns are chosen.
•
Values above 255 are mapped to 255. Values below 0 are mapped to 0. Contrast amount controls how much
Clip
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.
•
Remaps grayscale values to fall inside the 0–255 range. Contrast appears reduced; cells are mostly gray
Soft Clamp
with very few areas of pure black or white.
•
Values above 255 or below 0 are reflected back into the 0-255 range. For example, a value of 258 (255+3)
Wrap Back
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.
How randomly the pattern is drawn. Lower values cause more uniform or grid-like cell patterns.
Disperse
The size of the cells. The default size is 60.
Size
Determines the portion of the cell pattern that is used.
Offset
Choose Enable Tiling to create a pattern built of repeating tiles. Cells Horizontal and Cells Vertical
Tiling Options
determine how many cells wide and how many cells high each tile is.
Animating this setting results in changes of the pattern over time.
Evolution
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.
Provide controls that render the effect for one short cycle and then loop it for the duration of your
Evolution Options
clip. Use these controls to pre-render the 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.
