sRGB to Linear sRGB

If you compare the renders between Maya Render View and IT, you will see that Maya Render View has a darker output and that is because Maya Render View is using sRGB as default Image Color Profile. IT is using Linear as the default output.

To make Maya Render View to match the look of IT, you will need to change its color profile to using Linear sRGB.

Run the following MEL script to set the Color Profile to Linear sRGB:

setAttr "defaultViewColorManager.imageColorProfile" 2;

Run the following MEL script to set the Color Profile back to sRGB:

setAttr "defaultViewColorManager.imageColorProfile" 3;
