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

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.

•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
