LottieFiles plugin compatibility with AE v18 (2021)

After Effects auto-updated overnight last night and the LottieFiles plugin is no longer showing up within After Effects. Reinstalled LottieFiles and still nothing. Looking at the ZXP Installer, it looks like LottieFiles is only compatible up to After Effects 2020. I think this is why LottieFiles won’t show up in the extension options but I’m new to Lottie so I am not positive. Any thoughts?

You will need to manually edit manifest.xml to see the Lottie extension in the After Effects menu.
Go to C:\Program Files (x86)\Common Files\Adobe\CEP\extensions\com.lottiefiles\CSXS and open manifest.xml then edit with any text editor 17.9 into 99.9

before:
<Host Name="AEFT" Version="[13.0,17.9]" />

after:
<Host Name="AEFT" Version="[13.0,99.9]" />

where would I find this on a mac? Seems strange something this popular hasn’t been updated for 2021 yet?

I made the suggested change to the manifest (as described above). The plugin did indeed load into After Effects; I can see it in the menu; but it hangs when trying to launch the plugin. It does not work.

Is there any plan to update this plugin to officially support AE 2021? Bodymovin plugin does work as an alternative, but doesnt have the seamless integration with mobile apps etc. the way LottieFiles does. It would be nice to have an update.

I experienced the same thing in March. Either Lottie or Adobe patched it finally. I ended up completely uninstalling both the plugin and AE, disabling the plugin on the Adobe exchange, then reinstalling everything. LottieFiles showed up and worked properly without touching the manifest after that

Try deleting the cache in %temp%\cep_cache (windows).
AEFT_18.0_com.lottiefiles.panel
AEFT_18.0_com.lottiefiles.server

You can also run the extensions in debug mode by adding the registry entry “PlayerDebugMode” with String value 1 in HKEY_CURRENT_USER\Software\Adobe\CSXS.10
