Actually i posted this in the wip forum, but maybe you guys could help me with something. I did do an incandescent map, but i wanted to make lots of different coloured litghts, but when i use more than one color it doesn't work(if you use only red, white and black, it works fine). Anyone know a way to do this? A layered shader "sounds" right to me, but i don't know much about them, or how to use them.

here is my Movie thread in the WIP forum. The mothership with all the lights is at the bottom.
