I looked at the article. But I couldn't see much of a difference in the pictures. I'm modeling a person and thought I should start working on a texture for the skin. I would like to find a setting (if possible) so that there is a change in the object's texture color when it is placed directly between a light source and a camera lens. I'm playing with the DCG and Shoestring plugins to see which ones approach this.
