How Does It Work?
This is a fractal algorithm, so it has all of the typical fractal parameters (Roughness, Lacunarity, and Lacunarity Lock).
As the Rock Height parameter is increased, the smaller gravel pieces will become more pronounced and will start appearing on top of the larger gravel pieces.
The Gap Size parameter changes the space between gravel pieces. Since smaller pieces are more likely to
appear in the gaps of the larger gravel pieces, increasing the gap size allows more small gravel to appear. Increasing the gap size also reveals more of the Background.
Hints!
Try using low Lacunarity settings and a Small Gap size to get a scaly reptile like skin. Large Gap sizes can be used to get a spatter type texture.
