Installing the plugin

Install from Fab​

  1. Open the Epic Games Launcher and go to Unreal Engine → Library → Fab Library.
  2. Search for HostMigrationCore.
  3. Click Install to Engine and select 5.8.

Enable the plugin​

Open your project, go to Edit → Plugins, search for HostMigrationCore and make sure it is enabled. Restart the editor when asked. The plugin enables SteamShared as a dependency.

Installing manually (project plugin)​

You can also place the plugin in your project instead of the engine:

YourProject/
└── Plugins/
    └── HostMigrationCore/
        ├── HostMigrationCore.uplugin
        ├── Config/
        ├── Resources/
        └── Source/

Right click your .uproject → Generate Visual Studio project files, then build your project.
