Rock

Simulates rock using a random 3D distribution of two different grain material types.

Find this texture in the Create bar. To apply this texture as a texture map, see Map a 2D or 3D texture.

Tip Assign this texture to the material’s bump map to achieve a coarser simulated texture.

Color1, Color2

The color of the two grains in the texture. To select different colors, click the color bars to open the Color Chooser.

Grain Size

Specifies the grain size and scales the entire texture. The valid range is 0 to infinity. The slider range is 0 (no grains) to 0.1 (large grains). The default value is 0.01.

Diffusion

Controls the amount Color1 blends into Color2. The range is 0 to infinity. The slider range is 0 (no blending) to 1 (smooth blending). The default is 1.

Mix Ratio

Determines the dominant color. The valid range is 0 to infinity. The slider range is 0 (Color1 is totally dominant) to 1 (Color2 is totally dominant). The default is 0.5.
