Zero-centered 3D Fractal noise in 1, 2, 3 or 4 channels, created by summing several octaves of 3D Perlin noise, increasing the frequency and decreasing the amplitude at each octave.
The center-to-peak amplitude of the noise (peak-to-peak amplitude is 2× this value). Default is 1.0.
The number of octaves of noise to be summed. Default is 3.
The exponential scale between successive octaves of noise. Default is 2.0.
The rate at which noise amplitude is diminished for each octave. Should be between 0.0 and 1.0; default is 0.5.
The name of a vector3-type node specifying the 3D position at which the noise is evaluated. Default is to use the current 3D object-space coordinate.
