Noise Texture Parameters

Power - Determines the overall brightness of the noise pattern.

Noise Type - Select from five different noise generators.


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.
