    Engine Plugin
    This product contains a code plugin, complete with pre-built binaries and all its source code that integrates with Unreal Engine, which can be installed to an engine version of your choice then enabled on a per-project basis.

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.

* The engine versions listed at the top of this page refer to the engine versions that plugin binaries are available for. However, the Marketplace does not allow us to ship plugin updates for engines older than the last 3 releases, so we do not offer support for engines older than the last 3 versions through Standard Support. If you need support for older engine versions, please refer to our Premium Support page.
