Hi Yves, Well, why did I just know you'd post? ;) There really seem to be few people who are "fanatic" about lighting, which I think is a shame. I just love to play around with lighting very simple sets, IMO that's what makes or breaks a good image. Ambient light is evil. :D On the other hand side, the "final" render above still uses about 50% ambient lighting, the trick is not to forget when you can still use ambient light, and that you can use different colours as well. ;) I'll wrap up the tutorial next Friday. I think I'll make it two-part, i.e. short basic introduction as an "awareness" riser, and then some advanced stuff. Thanks for your feedback! -Sascha.rb
