cmoreink: thx bro and good luck with the hangover, hehe...
EDMON: hi bro, i think that night scenes is all about testing lights over and over until you have your desire result,,,but first test lights in your scene without applying quality or reflections to your materials and make sure your options settings are low and a small output, cause maybe you need to do many tests and this will helps to make thing faster, once you got the right ilumination, then start applying materials to the scene,change the setting to high and the output, in this order i think can be good, hope this helps, sorry for my bad english.
