Noise Texture

The Noise texture map is useful for creating and controlling intentional noise. There are four noise types:

• Perlin - Similar to the Turbulence node with Use Turbulence disabled.
• Turbulence - Similar to the Turbulence node with Use Turbulence enabled.
• Circular - Produces a Worley noise.
• Chips - Produces a Voronoi noise.

Noise Texture Parameters

Power - Controls the overall brightness.

Noise Type - Select from four different noise generators.

Octaves - Sets the noise detail's scale.

Omega - Controls the fractal pattern detail.

UVW 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.
