hi,
Im currently renderin a simple view of a building in day- and night time.
At night I want some windows to be lightend. I first tried wit an area light behind it but got black , after some render global tweaking, i got transparant back, bit not the nice night view one has when looking to a building at night. ).

So to solve this I changed the window colours

And ofcourse with not so nice results.
My aim is not to get a realistic image, but to get a nice image, anyone some critics?

edit: I have two images but can only upload one, so this one is the one without night sky etc...
