Color A – Controls the first color used by the Rock procedural. You can assign a texture map to this channel, which overrides the color if the checkbox is enabled. Color B – Controls the second color used by the Rock procedural. You can assign a texture map to this channel, which overrides the color if the checkbox is enabled. Grain Size – Controls the size of the fine grain features. Diffusion – Lower values make the resulting texture sharper, while higher values blur the texture details more. Mix Ratio – Controls the mix between Source A and Source B. Color Manipulation

When a texture is selected, it overrides the color as long as the texture checkbox is enabled. Color Offset – Corrects the color of the texture by adding the RGB color values specified here to the RGB color values in the texture. When a texture is selected, it overrides the color as long as the texture checkbox is enabled. Default Color – Specifies a default color used for polygons with no valid UVs. In case the map is not tiled, specifies a default color that is used outside the texture square. When a texture is selected, it overrides the color as long as the texture checkbox is enabled. |
