Testing Steam Functionality

This guide outlines important steps and requirements to ensure smooth testing of Steam integration in your Unreal Engine project.

Prerequisites for Testing

• Configure Steam settings properly in your DefaultEngine.ini. See detailed configuration instructions here.
• Ensure the Steam Client is running and that you are logged in.
• Verify that the Steam account used for testing owns the game. You can:
  • Add the Steam account to your app’s organization, or
  • Obtain Steam keys from Valve to activate the game on the tester’s account.

Testing a Packaged Build

• Always package your game as a Development Build for local testing.
• If packaging as a Shipping Build, you must upload the build to Steam and launch it via the Steam Client.

Packaging Using the Project Launcher

• Check out this tutorial on how to use the project launcher!

Multiplayer Testing

NOTE

You must use a Packaged game build to test multiplayer, testing in the editor is not going to work

• Multiplayer testing via Steam requires:
  • Two separate computers, each logged into different Steam accounts, or
  • One computer and a virtual machine (VM) setup.

Testing in the Editor

To test Steam functionality within the Unreal Editor, launch a Standalone Game instance.

UE4

Launch a standalone instance to initialize Steam.

UE5
