What you'll learn
In this series of NUKE tutorials, we will learn how to use the Channel system in NUKE. Channels are how NUKE stores image information through a node tree, and understanding this system is key to getting the most out of NUKE. We will begin this course by taking an overview of the red, green, blue, and alpha channels in NUKE. We then learn how we can copy, add, and view new custom channels. Using these new channels, we can control nodes such as ColorCorrect and have optimal control over specific parts of our image. We end by using the Copy and ShuffleCopy nodes to bring together multiple 3D render passes into channels in a single node tree, and then we output a multi-channel EXR file for easy use later down the line. This tutorial illustrates the basics of channels and, by bringing together the information of the channels, it makes for an easy compositing workflow. By the end of this training, you'll be ready to start working with channels on your own and start using multi-channel files for your composites in NUKE. Software required: .
