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
Invert Texture – Inverts the RGB texture values.
Alpha from Intensity – Uses the texture RGB intensity/luminance as alpha channel.
Color Gain – Corrects the color of the texture by multiplying the the RGB color values in the texture with the RGB color values specified here. 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.
