Alter HSV node — Material Maker documentation

# Alter HSV node

The Alter HSV node modifies the hue, saturation and value of the input image, according to dedicated input maps. It can be used to easily apply variations to its input.

## Inputs

The Alter HSV node requires a color input texture. It also has 3 grayscale input maps, one for hue, one for value, and one for saturation. Values above 0.5 increase the associated channel, and values below 0.5 decrease it.

## Outputs

The Alter HSV node provides a single color texture.

## Parameters

The Alter HSV node has the following parameters:

- All is used as a multiplier for all input maps and can be used to modify the overall alteration intensity.

- Hue defines how hue is affected, and is used as a multiplier for the corresponding input map.

- Value defines how the lightness is affected, and is used as a multiplier for the corresponding input map.

- Saturation defines how the colorfulness or the texture is affected, and is used as a multiplier for the corresponding input map.
