Iray+ Worley Noise

Iray+ Worley Noise, also known as Cell Noise, is a texture built by calculating the distance between randomly distributed points. This produces a pattern similar to clusters of cells, and can be used as an alternative to the Iray+ Perlin Noise map to generate texture effects and procedural textures.

Parameters

Color1

The noise blends between these two colors. These parameters will have no effect if connected to a Normal/Bump parameter.

Input: Color

Color 1 + 2

The noise blends between these two colors. These parameters will have no effect if connected to a Normal/Bump parameter.

Input: Color

Size

The size of the features in the noise pattern.

Input: 0 – 1000

Apply Marble

This modifies the pattern with a marble appearance. Can be used in combination with Apply Dent and Absolute Noise for more complex effects.

Input: On/Off Checkbox

Apply Dent

Intensifies the contrast between the colors but the pattern will stay the same. Can be used in combination with Apply Marble and Absolute Noise for more complex effects.

NoiseDistortion

The weight of additional noise turbulence.

Input: 0 – ∞

NoiseDistortion: 1.0 1.0 1.0 — NoiseDistortion: **1.0, 1.0, 1.0**

NoiseDistortion: 1.0 2.0 1.0 — NoiseDistortion: **1.0, 2.0, 1.0**

NoiseDistortion: 3.0 9.0 0.0 — NoiseDistortion: **3.0 9.0 0.0**

NoiseThresholdLow

Noise values greater then "Noise Threshold Low" are mapped to Colour2

Input: 0 – ∞

NoiseThresholdLow: 0.0 — NoiseThresholdLow: **0.0**

NoiseThresholdLow: 0.5 — NoiseThresholdLow: **0.5**

NoiseThresholdLow: 0.8 — NoiseThresholdLow: **0.8**

NoiseThresholdHigh

Noise values greater than "Noise Threshold High" are mapped to Colour1

Input: 0 – ∞

NoiseThresholdHigh: 1.0 — NoiseThresholdHigh: **1.0**

NoiseThresholdHigh: 2.0 — NoiseThresholdHigh: **2.0**

NoiseThresholdHigh: 3.0 — NoiseThresholdHigh: **3.0**

Noise Bands

This creates a "tree ring" like effect

✱ Note: The FlipTangent checkboxes on a geometry component's Normal parameter will not function if a Noise or Bump map is attached, only Normal maps will be affected.
