Checker map used for the tablecloth and (in a composite) for the floor of the ice-cream shop
The Checker map applies a two-color checkerboard pattern to the material. The default checker map is a pattern of black and white squares. Checker maps are 2D procedural maps. The component checkers can be either colors or maps.
Tip: Turning on Noise for a Checker map can be an effective way to create irregular patterns with a natural appearance.
To change the color of one set of squares:
In the Checker Parameters rollout, click a color swatch to display the Color Selector.
