FBM node

The FBM node outputs a fractional Brownian motion texture. FBM is obtained by repeating a noise pattern with smaller and smaller details.

Inputs

The FBM node accepts a single input, the Offset Input to optionally drive the Offset value with an input.

Outputs

The FBM node provides a grayscale noise texture.

Parameters

The FBM node accepts the following parameters:

Noise type: value, perlin, simplex, cellular types, voronoise or gabor noise
X and Y scale of the first octave noise
Number of Folds (offsetting the noise negatively and taking the absolute value)
Number of Iterations
Persistance, i.e. the strength of each subsequent iteration
Lacunarity, i.e. the scale of each subsequent iteration
Offset of the points, can be used to animate the noise
