1

Prepare and extract RealitySDK

• Move the RealitySDK.zip file to the root of your drive (e.g., C:).

This prevents long file path issues with Unreal Engine.

• Right-click the file and select Extract All...

Extract RealitySDK

This will be your root folder for the Unreality Engine.

2

Download and install the Unreality Engine

• Download the Unreality Engine (all six Engine.zip.00X files) from the same GitHub releases page.

• Place all six .00X files inside the extracted RealitySDK folder. (⚠️ See picture)

• Double-click RealitySetup.

ExtractUnrealityEngine

This process will extract the Unreality Engine and install the RealitySDK along with all required dependencies.

Once the installation is complete, Unreal Engine will prompt a confirmation window — click Allow to proceed. The engine will then launch automatically.

This requires at least 55 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.
