# Value noise node

The Value noise node outputs a texture generated as a sum of Value noise functions with increasing frequencies and decreasing amplitudes. Value noise has a wide range of applications, such as stains, wood, dust…

## Inputs

The Value noise node does not accept any input.

## Outputs

The Value noise node provides a greyscale Value noise texture.

## Parameters

The Value noise node accepts the following parameters:

- Scale X and Scale Y are the subdivisions of the first iteration

- Iterations is the number of iterations

- Persistance is the ratio between the amplitude of subsequent iterations. Lower values of persistance generate smoother textures.

## Example images

## Variations

- The Color Value node generates an RGB image made of 3 greyscale Value Noise images.

- The Value Warp1 and Value Warp2 nodes generate Value noise with domain warping.
