Use the Gamma Correct utility

For a description of the Gamma Correct utility, see Gamma Correct.

To remap colors using the Gamma Correct utility

1. Map a texture to a material’s Color and assign the material to an object.

   In this example, map a File texture to a Lambert material.

   

2. Map the Gamma Correct utility to the color you want to adjust, such as the Ambient Color for the Lambert material. To do this, in the Lambert material’s Attribute Editor, click the box next to Ambient Color, then select Gamma Correct from the Utilities tab in the Create Render Node window that appears.
3. Change the Gamma Correct attribute settings as necessary, as in the following.

   

   After you change the Gamma Correct attributes, the Ambient Color attribute updates in the Lambert material’s Attribute Editor.
