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 accepts a single input, the Offset Input to optionally drive the Offset value with an input.
Outputs
The FBM node provides a grayscale noise texture.
Parameters
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
