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.



The FBM node does not accept any input.


The FBM node provides a greyscale 3D texture.


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
