I have been playing with scenes that have no lights at all! I got the toon shaders set at Sixus1 for $2.95 or $6.95 or something like that... it is great. Has informative instructions and work beautifully. Really neat. Click to use... need no expertice at all. But I am working my way through their .pdf node tutorial ($6.95 I believe) and it is sooo understanable and helpfull. Also Rebekah (sp?) is really nice :) The image above is my first render. No lights. I have been post working these images in Photoshop to be like paintings.
