Lighting and Door Problems

[HakePT]

I encountered th same problem but with the correct and precise position in the boxlight it can be solved. Or if you want a better solution just use a point light. Should light most of the room.

Also it doesn't look natural that 2 rooms separated by a door, both with windows look so different. Unless its part of the story it won't look natural.
Tone down the box light and if you want the player to pick certain items (for example for him not to miss the lamp) just place small point lights (1~0.7 size) over the objects.
A neat trick i use to highlight doors, notes and some important items.
