Computes a 3D turbulent noise.

Since 22.0

Computes a 3D turbulent noise. See the Turbulent Noise VOP for more information.

Inputs

pos: Vector3

The position used to drive the noise.

freq: Vector3

The frequency of the noise. Higher values give smaller-scale details in the noise.

offset: Vector3

The offset of the input into the noise function. If you visualize the noise as a 2D graph or 3D height field, this has the effect of “panning” across the space of possible noise outputs. If you have a general noise effect but want to get a different set of values for a different look, try changing this offset.

amp: Float

Scales the noise by this value.

rough: Float

The scale increment between iterations of fractal noise that is added to the basic output. The higher the value, the more jagged the roughness added to the output. You can set the roughness to a negative value.

atten: Float

Flattens the noise to prevent extreme spikes by damping the values. Higher values create a smoother look.

depth: Int

Controls the degree of noise. Higher values create a more chaotic (less smooth) look with more peaks and valleys.

seed: Int

The seed of the noise.

type: Int

The type of noise. 0 is Fast, 1 is Sparse, 2 is Perlin, 3 is Alligator. Defaults to 1. An invalid value yields Sparse. See the Turbulent Noise VOP for more information.

Outputs

noise: Vector3

The turbulence noise.
