Adv Base Specifies a contrast base Affects pixel gamma settings without affecting the luminance level.

Adv Brightness Specifies a color multiplier for the base color Affects overall pixel color value.

Adv Contrast Specifies the color contrast value Affects pixel gamma settings.

Adv Offset – Specifies color offset.

Adv Rgb Base Specifies RGB contrast base. Affects the gamma value without changing the brightness of the pixel. 

Adv Rgb Brightness Specifies RGB multiplier color Affects the pixel brightness value if Adv Use Red/Green/Blue options are enabled.

Adv Rgb Contrast Specifies RGB contrast base. Affects the pixel contrast value if Adv Use Red/Green/Blue options are enabled. This option can be for used for gamma correction.

Adv Rgb Offset – Specifies an RGB color offset. Controls the overall brightness of the pixel color. 

Adv Use Blue/Green/Red – If enabled, uses the blue/green/red component for the Adv Rgb parameters.

Brightness – The specified value is added to the texture brightness.

Contrast Adjusts the correction of the color contrast.

Hue Shift – Shift added to the color hue.

Hue Tint Specifies a hue tintthe tinting color for the current colors.

Lightness Mode

Standard
Advanced

Specifies the lightness mode.

 Standard – Allows easy to use control and works with Brightness and Contrast options.
  Advanced – Simulates camera exposure and photo changes in maps.

Rewire Alpha/Blue/Green/Red Allows the following channels to be assigned into the RedGreenBlue or Alpha channels:

Red – Adjusts the strength of the hue tint Red  Assigns the red channel.
      Green 
– Assigns the green channel.
        Blue 
– Assigns the blue channel.
       Alpha 
– Assigns the alpha channel.
       Redinv 
– Assigns the inverse of the red channel. This option converts the color to Cyan.
       Greeninv 
– Assigns the inverse of the green channel. This option converts the color to Magenta.
       Blueinv 
– Assigns the inverse of the blue channel. This option converts the color to Yellow.
       Alphainv 
– Assigns the inverse of the alpha channel.
       Monochrome 
– Assigns the channel to be monochrome
       One 
Assigns Sets the channel to the highest possible value 1.
       Zero Assigns Sets the channel to the lowest possible value 0.

 

Saturation – Specifies a value for the saturation or desaturation of colors.

Source Color – Specifies the source color.

Tint Strength – Adjusts the strength of the hue tint.
