Requirements: This extension requires use of Javascript engine, which is available since CC 16.0. Please check your File>Project Settings>Expressions>Expressions Engine
The After Effects integration requires two components to work; extension and server.
To install the extension download Extension Manager Command Line tool (ExManCmd).
ExManCmd /install {path to avalon-core}\avalon\photoshop\extension.zxp
OR download Anastasiy’s Extension Manager
The easiest way to get the server and After Effects launch is with:
python -c ^"import avalon.photoshop;avalon.aftereffects.launch(""c:\Program Files\Adobe\Adobe After Effects 2020\Support Files\AfterFX.exe"")^"
avalon.aftereffects.launch launches the application and server, and also closes the server when After Effects exists.
The After Effects extension can be found under Window > Extensions > OpenPype. Once launched you should be presented with a panel like this:
When developing the extension you can load it unsigned.

ZXPSignCmd -sign {path to avalon-core}\avalon\aftereffects\extension {path to avalon-core}\avalon\aftereffects\extension.zxp extension.p12 avalon
