Noise Texture Node.

The Noise Texture node evaluates a fractal Perlin noise at the input texture coordinates.

Inputs

The inputs are dynamic, they become available if needed depending on the node properties.

Vector

Texture coordinate to evaluate the noise at; defaults to Generated texture coordinates if the socket is left unconnected.

W

Texture coordinate to evaluate the noise at.

Scale

Scale of the base noise octave.

Detail

Number of noise octaves. The fractional part of the input is multiplied by the magnitude of the highest octave. Higher number of octaves corresponds to a higher render time.

Roughness

Blend between a smoother noise pattern, and rougher with sharper peaks.

Distortion

Amount of distortion.

Properties

Dimensions

The dimensions of the space to evaluate the noise in.

1D

Evaluate the noise in 1D space at the input W.

2D

Evaluate the noise in 2D space at the input Vector. The Z component is ignored.

3D

Evaluate the noise in 3D space at the input Vector.

4D

Evaluate the noise in 4D space at the input Vector and the input W as the fourth dimension.

Obs

Higher dimensions corresponds to higher render time, so lower dimensions should be used unless higher dimensions are necessary.

Outputs

Factor

Value of fractal noise.

Color

Color with different fractal noise in each component.
