The Ridged Fractal node produces a fractal pattern in greyscale format (figure 1).

Power - Controls the Texture's overall brightness.
Ridge Height - Specifies the height of the fractal pattern's elevated parts.
Octaves - Controls the amount of detail in the texture.
Omega - Specifies the difference per interval.
Lacunarity - Controls the size of the gaps in the fractal pattern.
UVW Transform - Controls the surface texture's position, scale, and rotation.
Projection - Determines how the texture projects onto the surface.
