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 the following parameters:
|
||
|
|
|
||
|
|
* the noise type: value noise, fractal noise or cellular noise
|
||
|
|
* the *X* and *Y* scale of the first octave noise
|
||
|
|
* the number of iterations
|
||
|
|
* the persistance, i.e. the strength of each subsequent iteration
