Attached Link: Youtube Night light Tutorial

This tutorial can be applied to just about any 3d application, but here I am using Carrara.

The basic idea is to use moonlight with 4 distant lights each with their own colour shading and (low) intensity, in order to simulate the slow to render indirect lighting that is available under global illumination.

In addition to this set up I go into how contrasting addtional (brighter) lights with this lighting can help the whole scene look like night time.

The video is geared towards surviving youtubes encoding for darker lights. Of course using some kind of gamma correction is useful, but how about fixing the scene at source? Gamma correction can light up everything, here you can select what is to stand out.

Finally I mix a three point lighting idea with this set up to show how you can cheat and help individual objects stand out in the darkness.
