The Fractal Flow Noise procedural texture produces a 3D noise pattern comprised of two color parameters and a series of other parameters capable of animation (figure 1).

Colors 1 and 2 - Specifies the two colors used for the flow noise.
Flow - Controls the position of the noise pattern, capable of producing an animated effect.
Lacunarity - Specifies the size of the gaps within the noise pattern.
Flow Rate - A multiplier per iteration for the flow coordinate.
Gain - Amplitude multiplier per iteration, provides an overall contrast control for the noise pattern.
Advection - Provides both an initial advections amount and an advection multiplier per iteration, where higher values will smooth the noise results.
Octaves - Changes the number of octaves over which the noise function is calculated, otherwise known as frequencies.
Attentuation - The power of the falloff applied to the final result, providing an overall lightening or darkening of the noise pattern.
Step Noise - Provides a smooth noise result when disables, and a stepped noise result with enabled.
Transform - Positions, scales, and rotates the surface texture.
Projection - Sets how the texture projects onto the surface.
