Important: There have been few significant changes to the effect plug-in API for After Effects CC (12.0), so you should not need new versions of most plug-ins for After Effects CC (12.0), if you already have plug-ins that work for After Effects CS5, CS5.5, or CS6.
Separate from the issue of updates to the effect plug-ins themselves, there is the issue of their installers: Some plug-ins come with installers, and these installers may need to be updated to install plug-ins into the correct location.
One thing that I do that works for most plug-ins is to create a shortcut/alias in the new plug-in folder that points to old plug-in folder, so the new version of the application loads plug-ins from the old location. If you do this, you need to be careful to put the alias/shortcut at the right, lower level–i.e., not at the top level of the plug-ins folder–so that you’re only loading specific plug-ins from the old location; otherwise, you’ll get warnings about duplicate plug-ins.
Check the websites of the vendors of your plug-ins to see if you need an update for any reason.
Here are links to updates for several popular plug-ins:
- Red Giant plug-ins (more information about their update policy here)
- RE:Vision Effects plug-ins (Navigate to each plug-in’s Download section for updates.)
- ShapeShifter and FreeForm effect plug-ins from Mettle
