Maya: Create Light Coming through Windows

During the first half of this tutorial, I demo how to model the walls, windows, and ceiling of a room. During the second half, I show how to create light pouring in through the window by adding Atmosphere. There are three lighting components in this scene. 1) An Arnold Area light that emulates sunlight. 2) An HDRI skydome light & 3) The Atmosphere which helps create the light rays.
