Attached Link: multiple lights image

There are a couple of tutorials in renderosity and out in the web on how to use different approaches to lighting in Vue... If you look at the picture at the link above, there is no sun in that scene... All lighting was done with multiple spotlights, both indoor and out, to create the sunset feeling... The sun in the distance is a spotlight with a red filter applied... There's about 3 or 4 spots in the room... A couple more right outside... Lighting is one thing that you could spend months and months experimenting with and not exhaust the possibilities... An art teacher once said that with the right lighting, any subject can become a work of art... :)
