The mentalrayOutputPass node contains attributes that control camera output passes. For more information on mental ray camera output passes, see Appendix B: Creating camera output passes with mental ray for Maya.
This option causes mental ray for Maya to interpolate sample values between two known pixel sample values. If interpolation is turned off, the last sample value in each pixel is stored, and pixels without samples get a copy of a neighboring pixel. When this option is turned on, the resulting image has a higher quality, but takes more time to process.
Use this option when you are using color management in your scene. You must enable File Mode before you can use this option. See Using color management in your scene for more information regarding color management.
Select the color profile that your file texture is using.
There are two sections available in the Color Profile drop-down box. Under the first section, there is a list of built-in color profiles. Under the second section, there is a list of any existing color profile nodes that are currently in your scene.
Click the colorProfile node icon to create a colorProfile node and connect it to your current mentalrayOutputPass node.
If you select the Use Default Output Profile option under the list of built-in color profiles, Maya will use the Default Output Profile setting that you selected under the Color Management section in the Render Settings: Common tab.
In order to use color management in your scene, you must select the Enable Color Management option in the Render Settings: Common tab.
