# FBM node

The FBM node outputs a 3D fractional Brownian motion texture. FBM is obtained by repeating a noise pattern with smaller and smaller details.

## Inputs

The FBM node does not accept any input.

## Outputs

The FBM node provides a grayscale 3D texture.

## Parameters

The FBM node accepts the following parameters:

- the noise type: value noise, fractal noise or cellular noise, and their non-repetitive counterparts

- the X, Y and Z scale of the first octave noise

- the number of iterations

- the persistance, i.e. the strength of each subsequent iteration
