Creating environment lighting for a building

[Lupaz]

Hi,

I'm working on a 7th floor building. I'm trying to cover it from GI up to... say... between 4th and 6th floor aprox, so that it appears to be on the middel of a city surrounded by other buildings, without actually model those buildings.

I tried with a gigant tube, but it is reflected on windows. Unchecking "visible to reflections/refractions turns the tube off to GI too.

Any advice on this one??

Thankssssss
