This guide will walk you through the process of installing the Online Subsystem Blueprints plugin.
Once you have purchased Online Subsystem Blueprints on the Unreal Marketplace, you will be able to download and install it through the Epic Games Launcher. It will then be available for all projects on your machine.
It's highly recommended that you check out the example project when starting to use Online Subsystem Blueprints. It covers a ton of common use cases, such as creating and finding sessions, managing parties and more.
If you have source code access for the Online Subsystem Blueprints plugin, you can clone the Git repository or add it as a submodule. If you don't have source code access, log into the License Manager and upload your receipt to get access.
If your Unreal Engine project is in a Git repository, add it as a submodule like so:
git submodule add https://gitlab.com/redpointgames/online-subsystem-blueprints Plugins/OnlineSubsystemBlueprints
Then, launch the editor and open your project.
