I've tried the tutorials listed in Renderosity, but was extremely disappointed. Sydd's tutorial only talked about lights, but didn't show how to create what he was talking about. Poser Arcana has some weird animated tutorials which won't help if you want to work while you read. 3D-CC's tutorials lack polish. Some authors would benefit from learning basic spelling and grammar skills, and a lesson in tact. After months of fiddling, I've come to the realization that lighting is one of the critical skills to master. Now I'd love to learn from someone who knows their stuff, and knows how to communicate as well. If you've found a good lighting tutorial, please share the information. Thanks.
