This guide will walk you through the process of installing the Online Subsystem Blueprints plugin.

Installing the 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.

Download the example project

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.

Source code access

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 [email protected]:redpointgames/online-subsystem-blueprints Plugins/OnlineSubsystemBlueprints
git submodule update --init --recursive

Then, launch the editor and open your project.


You can also clone the repository using HTTPS using as the URL, but you must create a personal access token with the read_repository scope and use this personal access token as the password for HTTPS authentication. It is recommended that you use SSH URLs instead, as shown in the git submodule add command above.
