Integrating 3D applications with After Effects – Part 2: Working with mattes and channels
How can you take the output of your 3D applications into Adobe After Effects? This two-part series shows you how.
In Part 1 you saw how to export UV data from your 3D apps for use in After Effects. In Part 2, I show you how to create mattes in your 3D applications that you can export to After Effects. Multichannel OpenEXR files are an ideal format for storing your mattes.
This article concludes by showing you how to install and use the OpenEXR plug-ins from fnord to enable you to handle this format in After Effects.
