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.

Of course, its not perfectly realistic, but it is definitely adequate and realistic enough that a non-CG-oriented-person will see it as realistic.

Find out how to:

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


Int Light

    So i tried it, because i am in the situation makin rooms etc. I had a hard time gettin the same result. After a while i found out that i had to do the following: World/Raytrace/Attenuation set to around 4. Usually this is 10 i guess. And then i got your result nearly 90%..
    And that Clay Tipp is fantastic.

      In the environment tab, look for Samples in the Gather panel. The default is 5 - turn that up to something like 16

      Wow I guess I did forget to meointn the empty thing . I rerecorded this tut about 3 or 4 times so I guess I forgot on the final one :/ sorry But yes, it is a good idea. You can also then use the empty as the target for the focal point when using the defocus node
