Over on
Weapon of Mass Imagination I am currently taking on 3D lighting in all its glory and fury... It is a part of my CG art I've never really tackled seriously before, and I'm learning some interesting (and hard) lessons.

I'm engaged in a rather large (and some have rightfully claimed ambitious) attempt to break down 3D lighting to all its various isolated elements and
catalogue what each can do. You can visit
my current breakdown of ambient lighting here. Other variables of lighting are coming soon.
