Settings

Type – Specifies which type to use for the Cellular texture. The choices are Dots, Chips, Cells, Chess Cells, or Plasma.

Background Color – Controls the color of the background of the Cellular procedural texture.

Center Color – Controls the color of the center of the cells.

Edge Color – Controls the color of the edges of the cells in the Cellular procedural texture.

Size – Controls the size of the Cellular procedural texture. For more details, please see the Size examples below.

Spread – Controls the spread of the procedural Cellular texture. For more details, please see the Spread examples below.

Density – Controls the Density of the Cellular texture. For more details, please see the Density examples below.

Low – Controls the low threshold (background color). For more details, please see the Low examples below.

Middle – Controls the middle threshold (edge color). For more details, please see the Middle examples below.

High – Controls the high threshold (center color). For more details, please see the High examples below.

Fractal – Enables the addition of fractal generation. Only available with Dots and Chips Types.

Fractal Iterations – Controls the number of fractal iterations. For more details, please see the Fractal Iterations examples below.

Fractal Roughness – Controls the roughness of the fractal. A value of 0.0 is very rough and a value of 1.0 is very smooth, which negates the fractal. For more details, please see the Fractal Roughness examples below.

Color Tweaks

Default Color – Specifies the color when there are no valid UVW coordinates.

Mult – Specifies a strength multiplier for the texture color.

Offset – Color corrects the texture by adding the RGB color values specified here to the RGB color values in the texture.

Invert – When enabled, inverts the resulting texture color.

Alpha Tweaks

Source – Specifies where the alpha channel is drawn from:

Alpha – Alpha channel is drawn from the texture.
Color – Alpha is generated from pixel intensity.
