Dustin talks about using the Beauty pass in the Octane. Breaking apart your render into several different elements gives you the ability to isolate specifics of the file. Beauty passes are elements or layers that make up your “final” rendered image. These passes are greatly useful in compositing for adding the final polish. They can be used to enhance elements and most importantly save time when making tweaks. Whether working off of a beauty image or rebuilding an entire render from passes, beauty passes are a vital part of the post process.
