The AlterHSV 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.
The AlterHSV node requires a color input texture. It also has 3 greyscale 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.
The AlterHSV node provides a single color texture.
The AlterHSV 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.
