Noise Procedural

The Noise procedural node creates and controls the appearance of intentional noise. There are five noise types:

Figure 1: Examples of the various noise types available with the Noise texture node

Noise Texture Parameters

Noise Type - Select from four different noise generators.

• Perlin - Similar to the Turbulence node when you disable Use Turbulence.
• Turbulence - Similar to the Turbulence node when you enable Use Turbulencebut produces more contrast than the Perlin option. .
• Circular - Produces a Worley noise-like pattern.
• Chips - Produces a Voronoi noise pattern similar to Perlin but with a denser pattern.
• Voronoi - Produces a Voronoi pattern.

Octaves

Sets the noise detail's scale.

Omega

Controls the fractal pattern detail.

Transform

Positions, scales, and rotates the surface texture.

Projection

Sets how the texture projects onto the surface.

Invert

Inverts the Noise texture values.

GammaThe function or attribute used to code or decode luminance for common displays. The computer graphics industry has set a standard gamma setting of 2.2 making it the most common default for 3D modelling and rendering applications.

Adjust the Noise texture's luminance values.

Contrast

Adjusts the Noise detail sharpness.
