Hi Gang, 

I was cleaning my computer and came across this little tidbit. It's a lighting tutorial that 3D World magazine commissioned me to do. It doesn't show some of the cool features like negative lights – but it shows some decent tricks. 

The movie I uploaded to here: http://youtu.be/-S8xSrtNnOo

The following images show the scene unlit and untextured, then lit but with texture lighting effects, and finally the whole scene. 

Let me know if you have any questions.
