Native light linking in mental ray
 
 
 

Beginning Maya 2008, mental ray for Maya uses mental ray native light linking. This process occurs automatically. This feature simplifies your workflow for both the integration of custom mental ray shaders and mental ray shaders provided with Maya. For more information, see Native mental ray light linking of the Shading book.

NoteIf you have a scene created using Maya 8.5 or below, you may need to re-export your .mi files to mental ray.
