                           The Falloff map also includes a Mix Curve graph and rollout that give you precise control over the falloff
                           gradient. Points at the top of the graph have a value of 1 and represent the white areas of falloff. Points at
                           the bottom of the graph have a value of 0 and are black.

                           Marble map
                           The Marble 3D map creates a marbled material with random colored veins. The Marble Parameters rollout
                           includes two color swatches: Color #1 is the vein color and Color #2 is the base color. You also have the
                           option of loading maps for each color. The Swap button switches the two colors. The Size value determines
                           how far the veins are from each other, and the Vein Width defines the vein thickness.
                           Figure 17.19 shows three Marble maps with Vein Width values of (from left to right) 0.01, 0.025, and 0.05.

                           Noise map
                           The Noise 3D map randomly alters the surface of an object using two colors. The Noise Parameters rollout
                           offers three Noise types: Regular, Fractal, and Turbulence. Each type uses a different algorithm for comput-
                           ing noise. The two color swatches let you alter the colors used to represent the noise. You also have the
                           option of loading maps for each color. The Size value scales the noise effect. To prevent discontinuities, the
                           High and Low Noise Threshold can be used to set noise limits.
                           Figure 17.20 shows Noise maps with the (from left to right) Regular, Fractal, and Turbulence options
                           enabled.
