MentalRay has two solutions for computing additional light distribution in the scene. One is Globall Illumination, and other is Final Gather. In some situations, you can use only one of this solutions, but the most powerfull thing is to combine these two together.
   
maya interior illumination with gi and final gather videotutorial Globall Illumination shoots photons from light and tracks their distribution in the scene. It is fast solution, and produces nice additional lighting of the scene, but it isn't as accurate as we want it to be. That's why you must combine it with second method , the Final Gather. The goal of final gather is same as global illumination, but aproach is very different. Final gather is computed from point of view, and not from the light source like global illumination. After primary ray hits the point on objects, final gather is activated and shoots additional rays in the scene collecting color informations around the point for which we are computing color.
