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 does not accept any input.

Outputs

The FBM node provides a greyscale noise texture.

Parameters

The FBM node accepts the following parameters:

  • the noise type: value noise, fractal noise or cellular noise

  • the X and Y scale of the first octave noise

  • the number of iterations

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