Hi there,
Although indicated as compatible with 4.27 on the Reallusion homepage, I'm getting a "Missing Modules" error when trying to activate the plugin in the editor.
Does anybody else faces this kind of issue? Or has any ideas why this is happening?

Works fine here .
Looks like you don't have the right Live Link Version installed.
You can get the UE4.27 Live Link Setup over the Reallusion Hub.

Thanks SM!
Ok, got it to work, but I had the right Live Link Version.
I had to uninstall my 4.27 version and did a fresh install, which fixed the issue. Maybe something to do with the previous pre-releases...

Anyhow it is working now.
