amp: the strength of the initial octave wavelengths lacunarity: the spacing between octaves seed: the seed of the random noise generation octaves: the amount of noise octaves to use gain: the strength of the latter octave wavelengths scale: scale the whole noise system turbulence: sets the octave wavelength addition to positive time: the time frame of the shader direction(ppg hidden): the noise space ray vector to translate per frame of animation texture space: the uv space to use for noise space calculations external coordinates: uses the 'coord' vector input (ppg hidden) instead of the above uv space.
