I was planning to animate this scene but as it turns out it has some nasty cloud flickering issues. .. I was just wondering what are the key elements that cause the flickering and how to reduce it.. GI blur radius is surely one but it doesn't seem to be enough. Also my server is currently missing it's graphic card so I wont be rendering anytime soon but for the future I'd like to know how to make this work. Any ideas and tips are welcome!
