FBM node

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



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


The FBM node provides a greyscale noise texture.


The FBM node accepts the following parameters:

  • the noise type: value, perlin, simplex, cellular types or voronoise noise

  • the X and Y scale of the first octave noise

  • the number of folds (offsetting the noise negatively and taking the absolute value)

  • the number of iterations

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

  • the offset of the points, can be used to animate the noise
