Cinema 4D Quick Tip - Physically Accurate Metal (Octane)

Designer and animator Guy walks through his process on creating procedural metal materials using Octane Renderer in Cinema4D. He shows how you can dial in various metal types as well as how to add imperfections to help generate more realistic results. Since these materials are procedural, meaning they use algorithms instead of bitmap textures, they are highly flexible and extendable. 

I followed this tutorial months ago when I was exploring how to create a library of metal materials. The IOR site he references is invaluable and one I have bookmarked. The video is short and dense, which is great if you're familiar with Octane, but can be daunting if you're just getting started. The section on procedural imperfections flies by, but the more you become comfortable with Octane's Node Editor the easier it is to see what he's doing. A lot of what he's doing is repetitive. Nodes such as UV Transform, Gradient, Dirt and Noise will become your friends the more you dive into Octane or any renderer for that matter. He sells his package of metal materials at a great price. I recommend picking them up for your own projects or even to be able to open each material up in the Node Editor so you can spend more time understanding how they are constructed.
