GI looks fantastic for stills, but once you try to have a character move through the scene, you will often get a lot of flickering and speckling because of the nature of GI. It is possible to minimize this by increasing your GI samples or by adding Final Gather to the solve, but not without increasing render times. To solve this problem, Leonardo came up with a solution - make a daylight rig that looks like GI, that wont flicker, and that renders quickly.
