A Recipe for Precisely Clamping Your Render
HJ Hornbeck dives into Cycles and researches the way clamping works. It’s a great read if you’re looking to better understand some principles behind the Cycles renderer.
HJ Hornbeck writes:The Clamp Direct and Clamp Indirect values have been haunting me for the last few weeks. Nothing I’ve seen on the web gave a good in-depth explanation of how those values work, though, let alone how to set them. So I dug in and wrote a two-part tutorial that fills that gap. All pros in the crowd can skip directly to part two, where I walk you through a five-minute recipe for actually setting the values, but part one lays some important theoretical groundwork and might teach you a thing or two about how Cycles works.
