It is intended to be compatible with any Weather mod such as Climates of Tamriel.
It would eliminate the need for mods such as Relighting Skyrim, Volrath's various lighting fixes, and Enhanced lights and FX. This mods goal is to provide all the lighting fixes needed including flickering and elimination of shadow striping, and to do so without the use of post processing such as ENB. Updates to provide exterior lighting will be available shortly.
It currently provides interior lighting, some lighting for spells, and a preliminary version of lighting for weather.
Realistic Lighting Overhaul is the new lighting mod that replaces Realistic Lighting with Customization.
