[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.

Bake your skylight, or if you have to have it movable (which it sounds like it is), fade it out when you’re completely indoors.

how would you do that?
