Multi-Channel Compositing in NUKE
In this series of tutorials, we will go through the process of using a single EXR file to do a multi-channel composite in NUKE. Software required: NUKE 7.0v6.
What you'll learn
In this series of tutorials, we will go through the process of using a single EXR file to do a multi-channel composite in NUKE. This training picks up where the tutorial Introduction to Channels in NUKE left off. We start out with a single file that we use in combination with Shuffle and Merge nodes to bring the composite to life. Some of the channels are easy to add in, and some require a little more attention to make it look like a realistic car. This tutorial teaches you how to use channels to make a great composite, but it also shows you which nodes you can use with your channels to make them more realistic than ever. By the end of this training, you'll understand the thinking behind the channel compositing workflow. You'll also gain the knowledge you need to troubleshoot your own multi-channel composites when things aren't looking quite right. Software required: NUKE 7.0v6.
