Installation

This guide explains how to install and enable SteamSAL in your Unreal Engine project from source.

If you prefer, you can skip the source installation and directly install the plugin from the Epic Fab Marketplace, then simply enable it in your project.

Requirements

  • Unreal Engine: Tested and fully compatible with 5.0, 5.1, 5.2, 5.3, 5.4, 5.5, and 5.6
  • Steamworks SDK: v1.57 (or compatible version bundled with the OnlineSubsystemSteam)
  • Platform: Windows (64-bit). Linux/Mac support planned but not tested.
  • Online Subsystem: OnlineSubsystemSteam must be enabled

✅ The plugin has been verified to work across all Unreal Engine 5 versions listed above.

Installation Steps

1. Download the Plugin

2. Enable the Plugin

  1. Open your Unreal Engine project.
  2. Go to Edit → Plugins.
  3. Find SteamSAL – Steam Achievements & Leaderboards under the “Installed” category.
  4. Enable it and restart the editor.

3. Configure Steam Subsystem

Follow the official Unreal Engine guide to properly set up the Online Subsystem Steam for your engine version:
👉 Epic Games Documentation – Online Subsystem Steam Interface

⚠️ Make sure you configure your App ID and enable the subsystem correctly for Steam to initialize in your project.

4. Rebuild the Project

  • C++ projects: Regenerate project files and build.
  • Blueprint-only projects: Unreal will automatically compile the plugin when the editor starts.

Verification

To confirm SteamSAL is working correctly:

  1. Launch your game as a Standalone Game or as a Packaged Build.
  2. Steam must be running in the background and your Steam account logged in.
  3. In the editor, add the Is Steam Available node.
  4. If Steam initializes correctly, it should return True.

⚠️ Steam will not initialize when running in Play-In-Editor (PIE) mode.
To see the Steam overlay and use Steam features, always run in Standalone or Packaged Build mode.

Next Steps

Once installed, you can begin using:
