The Lyra's Readme.md from Github is not clear on how to setup the project for usage. Following the https://github.com/EpicGames/UnrealEngine/blob/ue5-main/Samples/Games/Lyra/README.md instructions and copying only the Content folder from the Unreal Marketplace version downloaded through the Epic Games Launcher is not sufficient to be able to run the Lyra project downloaded from Github. Many other uasset files are also missing from plugins and without them the Lyra project does not work properly. Even if the text meant "Copy all Content folders", it is not clear, and the licensee had trouble with it.
When fetching the Lyra project from Github at the link https://github.com/EpicGames/UnrealEngine/tree/ue5-main/Samples/Games/Lyra users would refer to the Readme.md file for instructions on how to use the project, but the instructions are insufficient.
Copying only the Content folder from the Unreal Marketplace version downloaded through the Epic Games Launcher is not sufficient to be able to run the Lyra project downloaded from Github. Many other uasset files are also missing from plugins and without them the Lyra project does not work properly.
Expected result: the steps described on Readme.md should be sufficient to enable users to run that version
Actual result: copying only the Content folder still leaves a lot required assets behind, making the project not run properly
Some warnings and erros we get by only copying the Content folder:
