I was responsible for doing the lighting in some areas of the campaign mission "Excavation Site". Specifically in the tunnel that leads into the beginning of the following mission.

There are actually two different lighting scenarios here. The cave has a more natural blue lighting before the laser activates, and after the laser activates the tunnels fill with smoggy warmth.
I also did the cubemap reflection work in this area as well as optimization work in the exteriors of Excavation Site.
