[Question] Indoor & Outdoor Lighting?

Does anyone know of any great pdfs/ video demonstrations/ techniques/ threads of lighting a level that includes both indoor and outdoor areas? I'm working on a multiplayer level for UT4 that takes place at sunset. I'm trying to create a warm outdoor and cool indoor environment, but I'm struggling to separate the lighting for the outdoor and indoor areas. The skylight seems to affect all rooms (giving a reddish ambient light to all rooms) Thank you.
