Defines the gamma correction for the roughness texture property.
|Excepted Data Source||1 component value|
|Data Range||greater than 0|
The roughness.gamma texture property is linked with the roughness texture property. It defines the gamma correction to be used for the roughness values. This can be used to use an sRGB color space image instead of a linear color space image as is the default.
The source is typically a single component value greater than 0.
The default value for this texture property is 1 which is the gamma correction for linear images.
