Unreal Plugin

After months of development, we are excited to announce the launch of the official mod.io plugin for Unreal Engine 4, featuring a blueprint and C++ interface.

Posted by on (updated ago)

Building drop-in plugins for popular engines and languages that make supporting user-generated content in-game is our primary mission at mod.io. We want more games on more platforms to be able to open themselves up to the creativity of their community. To accomplish this, earlier this year we announced the launch of our Unity Plugin for mod.io. Today we are pleased to announce the launch of the Unreal Engine Plugin for mod.io.


Features Include

  • Platform agnostic (support 1 click mod installs on Steam, Epic Games Store, Discord, GOG, itch.io and even consoles in the future)
  • Clientless (it has no other dependencies and works behind the scenes in your game)
  • Powerful search, filtering and tagging of mods
  • C++ and Blueprint interface built in the Unreal Engine for connecting to the mod.io API
  • Players can activate / deactivate mods they are subscribed to with automatic downloads
  • There is an example project to help get you started
  • Open source, available on Github
  • Our FAQ covers this in detail

Who's using it

The first release is already in use by MORDHAU and Playcraft, two UE4 games who we thank massively for being early adopters, and helping us refine the product. It has already powered over 1 million mod installs in its first month of operation, with VR and other games coming soon!

Launch Stream

To celebrate the launch, Victor from Epic Games invited us onto the Unreal Engine live stream, to discuss the plugin, how it works and what our objectives are. Included below is the video from the livestream as well as the slide deck we presented.

Benefits of using mod.io

mod.io offers the same core functionality as Steamworks Workshop (1 click mod installs in-game), plus mod hosting, moderation and all of the critical pieces needed. Where we differ is our approach to modding and the flexibility a REST API offers. For example:

  • Our API is not dependent on a client or SDK, allowing you to run mod.io in many places such as your homepage, launchers and even create discord bots
  • We don't apply rules globally, so if you want to enable patronage, sales or other experimental features, reach out to discuss
  • Our platform is built by the super experienced ModDB.com team and is continually improving for your benefit
  • Your community can consume the mod.io API to build modding fan sites or discord bots if they want
  • Communicate and interact with your players, using our built-in emailer

Large studios and publishers

A private white label option is available to license, if you want a fully featured mod-platform that you can control and host in-house. Contact us to discuss.

Install instructions

Getting mods installing takes minutes:

  1. Download the Unreal Engine Plugin and import it into your project
  2. Set up your game on mod.io (or our private test environment) to get your game ID and API key
  3. Input your ID and API key in the mod.io settings dialog
  4. Connect to the mod.io API using the blueprint or C++ interface
  5. An example project is available which shows you all of this working
  6. Setup complete!

All mods submitted to mod.io will be automatically fetched and managed by the plugin, and are instantly downloadable and testable. Any questions feel free to jump on our Discord to chat to our development team and community.
