Check box When on, enables the map. When off, disables the map (cell color reverts to the color swatch). Variation Varies the color of the cells by randomly altering RGB values. The higher the variation, the greater the random effect. This percentage value can range from 0 to 100. At 0, the color swatch or the map completely determines the cell color. Default=0. Division Colors group These controls specify the color of the divisions between cells. Cell divisions are a ramp between two colors or two maps. Color swatches Display the Color Selector for choosing a cell division color. Map buttons Assigns a map to one of the cell division colors. Check boxes When on, enables the associated map. When off, disables the associated map (the division color reverts to the color swatch). Cell Characteristics group These controls change the shape and size of the cells. Circular/Chips Lets you choose how cell edges look. With Circular, the cells are circular. This gives a more organic, or bubbly look. With Chips, the cells have linear edges. This gives a more chipped or mosaic appearance. Default=Circular. Size Alters the overall scale of the map. Adjust this value to fit the map to your geometry. Default=5.0. Spread Alters the size of individual cells. Default=0.5. Bump Smoothing When you use a cellular map as a bump map on page 5478, you might encounter aliasing or jagginess at the boundaries of the cells. If this occurs, increase this value. Default=0.1. Fractal Defines the cellular pattern as a fractal, thus enabling the three following additional parameters. Default=off. Iterations Sets the number of times the fractal function is applied. Caution: Increasing this value increases rendering time. Default=3.0. Adaptive When on, the number of fractal iterations is set adaptively. That is, the number of iterations increases the closer the geometry is to the scene's point of view, and decreases in the distance. This reduces aliasing and also saves time while rendering. Default=on. 5868 | Chapter 19 Material Editor, Materials, and Maps
