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
