fBm Node

Access: Nodes > Procedural > Fractal > fBm

The fBm (Fractal Brownian Motion) node generates a procedural, fractal pattern. This can be used in the same way as any other procedural node to make masks or height maps to create various textures and effects.

fBm Node Properties

Scale

text field, slider

This defines the overall scale of the effect.

Scale: 0.5 Scale: 1 Scale: 5

Octaves

text field, slider

This controls the number of iterations of the effect.

Octaves: 0.5 Octaves: 2 Octaves: 10

Frequency

text field, slider

This defines the turbulence of the resulting effect. A higher value gives a more turbulent effect.

Frequency: 1 Frequency: 5 Frequency: 10

Amplitude

text field, slider

Low values give a soft gradient. High values push the noise to the extremes.

Amplitude: 0.5 Amplitude: 1 Amplitude: 5

Gain

text field, slider

The Amplitude value is multiplied by this value for each iteration.

Gain: 0.1 Gain: 0.5 Gain: 1

Space

dropdown list

This specifies the space the effect should be applied in, 3D world space or 2D UV space.

Color

Color A

color select

This defines the base color.

Color B

color select

This defines the color of the fBm pattern.
