Noise Procedural

The Noise procedural node creates and controls the appearance of intentional noise (figure 1)

Noise Texture Parameters

Power - Determines the overall brightness of the noise pattern.

Noise Type - Select from five 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.

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.

Transform Input - Positions, scales, and rotates the surface texture.

Projection Input - Sets how the texture projects onto the surface.
