Rendering and Lighting Tips. Keep the number of lights you use to a minimum. The more lights you add, the longer each rendering will take. Do not add every light that would be in the scene in real life. Rendering does not replicate real life, it is your interpretation of it. Often, a few lights will give a better result.
Use a Renderworks Background to help fill in the background. A simple sky background will improve an exterior rendering. If you are rendering an internal view with windows, the background will help.
