Also note everyone that only the SOURCE for Lyra is available on GitHub.
You must also get the Content from the Epic Games Launcher.
Combining the two is easy. Automate the process for yourself.
I wrote up example PowerShell to copy the source from a GitHub clone and the Content from a sample project created via the Launcher.
You don’t have to actually run this script yourself if you don’t want, but do read it to understand what it does. You will need to do similar things yourself in your environment.
