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 greyscale 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
