FBM node — Material Maker documentation

# 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
