UE4 Blueprints Project Relighting - CGMA Art of Lighting for Games week 4

Relighting practice I did during CGMA Art of Lighting for Games week 4. Completed in ~10hrs from scratch. Based on Blueprint project from UE sample projects.
This time I decided to make neutral daylight scene, so main lighting comes from the sun light. Scene uses common warm/cold contrast in colors.
The room with control panel has different design - while main hall is sort of futuristic, control panel room is more industrial, that's why I used red/green combination - it is more common for machinery and factory theme. Also red is color of caution.
