  • Seed: Seed used to generate the noise. Every seed generates a different pattern.
  • Width, Height: Size of the noise "features".
  • Lattice Noise, Lattice Turbulence, Sparse Noise, Sparse Turbulence, Skin, Puffy, Fractured, Crystals, Galvanized: These are the available basis functions.
  • Ordinary fBm, Multifractal, Inverse Multifractal: These specify how the several octaves are blended together:
    • fBm: The octaves are added together.
    • Multifractal: The octaves are multiplied together, each octave dampens or enhances the features of subsequent layers.
    • Inverse Multifractal: Same as multifractal, but reverses the enhancement and dampening.
  • Octaves: Specifies the number of "noise layers" which get blender together to generate the final image.
  • Lacunarity: Specifies the size ratio between successive octaves. ie. If Lacunarity is 2, then every octave has half the feature size of the previous octave.
  • Hurst Exponent: Specifies how much the magnitude of successive octaves decreases. ie. A hurst exponent of 0 makes every octave contribute equally to the final image.
