→The rock effect

Here, <base-color> is a rgb triplet with color values ranging from 0 to 1 specifying the primary hue of the rock to be drawn. <ontrast> regulates how strongly the noise modification of rock brightness will appear from 0 (no noise modulation) to 1 (full noise modulation). <grain-fade-power> regulates the balance between large-scale and small-scale noise. Values above 1 will emphasize small-scale structures, values below 1 will emphasize large-scale structures. There is no real limit to the parameter, but presumably values outside [0.5:1.5] won't look compelling. | Here, <base-color> is a rgb triplet with color values ranging from 0 to 1 specifying the primary hue of the rock to be drawn. <ontrast> regulates how strongly the noise modification of rock brightness will appear from 0 (no noise modulation) to 1 (full noise modulation). <grain-fade-power> regulates the balance between large-scale and small-scale noise.
