Now you can access the online subsystems that Unreal Engine provides from blueprints. With over 290+ functions (100+ async) and 100+ events supported, you can create friend list UIs and party invite systems, all without touching C++!

For a full list of supported functions and events, please refer to the documentation before purchasing. This list will expand over time.

To access EOS from blueprints, you have two options:

  • Redpoint's EOS plugin which is fully supported and well tested.
  • Epic's plugin which is in beta and has known issues. You must read the important compatibility notes if you intend to use OSB with Epic's plugin: we will not be able to fix these issues as they are bugs in Epic's implementation.

If you're unsure or want the best support, you should use the Redpoint EOS plugin.

Example projects with different subsystems:

  • Redpoint's EOS subsystem
  • Epic's EOS subsystem - please read: important compatibility notes
  • Steam subsystem
  • Null subsystem
  • Online Subsystem Blueprints will work with other subsystems as well, but these are the ones we provide example projects for.

Supported Engine Versions

  • UE 5.1
  • UE 5.0

  • For newer engine versions, or if you are using a custom build of the engine, please reach out to our support channels after purchase and we'll help you get it working on the version of the engine you are using.
