fBm Node Properties
|
Scale text field, slider |
This defines the overall scale of the effect.
|
||||||
|
Octaves text field, slider |
This controls the number of iterations of the effect.
|

Amplitude text field, slider |
Low values give a soft gradient. High values push the noise to the extremes.
|
||||||
|
Gain text field, slider |
The Amplitude value is multiplied by this value for each iteration.
