Yes, I echo the guys above. Throw up an IBL light for general GI, but put AO on objects through the material room shader nodes. Use a spot or point light to make eyes glow or explode a bright spot on your set/character/hair. As soon as you turn AO on, you are into ray trace. Be sure to turn on off "visible in raytrace" for any dynamic hair. Occlusion Master rocks! ::::: Opera :::::
