I’ve been asked many times for this tutorial – most people thought that it was impossible to do this in Blender Internal, but as always, I like to prove them wrong.

Find out how to:
Make soft shadows from the sun
Use ambient occlusion and environment lighting simultaneously
Create atmospheric light
Included Tip: Clay rendering
