What you will learn
在这一系列的教程中，我们将要经历的过程使用一个单一的EXR文件做一个多路复合NUKE。
In this series of tutorials, we will go through the process for using a single EXR file to do a multi-channel composite in NUKE.
我们开始了与一个单一的文件，我们使用结合的Shuffle和合并节点带来的复合生活。一些渠道方便地添加，有些需要多一点的关注，使它看起来像一个现实的汽车。本教程教您如何使用做出了巨大的复合渠道，但它也表明你哪些节点，你可以用你的渠道，使他们比以往任何时候都更加逼真。
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.
通过本次培训结束时，你就会明白背后的思维通道合成工作流程。您也将获得你需要的知识来解决你自己的多渠道复合时，事情并没有看起来不太正确。
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.
