Node Overview



Node Ports


  • Input

The input texture to change


  • Balance

Adjusts the Balance of the Input Texture. Replaces the Slider value if mapped


  • Contrast

Adjusts the Contrast of the Input Texture. Replaces the Slider value if mapped


  • Brightness

Adjusts the Brightness of the Input Texture. Replaces the Slider value if mapped


  • Mask

Optional Mask to limit the effect



Node Properties


MAIN TAB


  • Balance

Adjust the Balance of the Input Texture


  • Contrast

Adjust the Contrast of the Input Texture.


A default contrast midpoint of 0.5 is used.


  • Brightness

Adjust the Brightness of the Input Texture.

The algorithm used depends on the Brightness Mode


  • Invert

Invert the corrected result



  • Clamp Output

Clamp the Output of this Node


  • Min

The Minimum value to clamp to


  • Max

The Maximum value to clamp to



  • Traditional Brightness Mode


Turning the Traditional Brightness Mode on, will switch the Brightness Calculation to the the algorithm commonly used inside of Mari to adjust Brightness. 



    • Left Side:Traditional Brightness OFF
    • Right Side : Traditional Brightness ON
    • Stepping through values from -1 to 1 in 0.1 incremented




  • Mask Intensity

Control the intensity of the effect.

If a Mask it attached to the Mask port of the node this will control the intensity of the supplied mask
