Get The Modkit

If you’re seeing a 404 page, make sure your GitHub account is linked to your Epic account. Learn how to connect and get access here: https://www.unrealengine.com/ue-on-github?lang=en-US

1

Download RealityLauncher.exe

Download the last version of the RealityLauncher.exe from the release page. Ignore the Source code files:

https://github.com/AtlasXRInc/RealityLauncher/releases

If your browser shows a security warning, click Keep. Then open the dropdown and click Keep anyway.

Run RealityInstaller.exe.

2

Authenticate to Github

Click Authenticate. GitHub opens in your browser.

When prompted, enter the code shown in the installer.

Complete the GitHub flow to verify your account.

3

Install the modkit

Click Install. The installer downloads and installs Unreality Engine, RealitySDK, and all required prerequisites.

Install to your C: drive instead of a deep subfolder. This avoids long file path issues in Unreal Engine.

This requires at least 15 GB of free space.

Understanding Unreality vs Reality

  • Unreality Engine is Atlas XR and Meta’s fork of Unreal Engine, optimized for VR. It’s updated rarely and is the base engine you’ll build on.

  • RealitySDK is the modkit. It’s updated frequently and contains the SDK tools you’ll use when creating mods.

Setting Up Your Project

If you don’t have a Modkit Unreal project yet

1

Open Unreality

It may take a few minutes to compile the first time you open it.

2

Create a new project

In the Unreal Project Browser:

  • Select Blank Project

  • Choose Blueprint (not C++)

  • Click Create to make a new project.

3

Enable the Reality plugin

Once the project opens:

  • From the top ribbon, click Edit → Plugins.

  • Search for Reality.

If the Reality plugin is missing

Close the project and go to C:\RealitySDK\Tools and run RealityUpdater.bat to install the latest version. You can also download it manually here.

  • If it's disabled, click the checkbox to enable it.

  • Restart the editor when prompted.

If you already have a Modkit project

Make sure you are using the correct Unreal version. Right-click your .uproject file → Switch Unreal Engine Version → select the path to Unreality.

Create your first mod

1

In the Unreal Editor, open the Reality dropdown (top menu bar).

2

Select New Mod.
