{% endhint %}

{% stepper %}
{% step %}

### Prepare and extract RealitySDK

* Move the RealitySDK.zip file to the root of your drive (e.g., C:).&#x20;

{% hint style="warning" %}
This prevents long file path issues with Unreal Engine.
{% endhint %}

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

![Extract RealitySDK](/files/c567658d2979751d3630750bbcf04f20a4afa19b)

This will be your root folder for the Unreality Engine.
{% endstep %}

{% step %}

### 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](/files/5692232045dc5b85320fe0c1164b53aa6d1bddc1)

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.
{% endstep %}
{% endstepper %}

{% hint style="warning" %}
This requires **at least 55 GB of free space**.
{% endhint %}

### 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

{% stepper %}
{% step %}

### Open Unreality

It may take a few minutes to compile the first time you open it.
{% endstep %}

{% step %}

### Create a new project

In the Unreal Project Browser:

* Select **Blank Project**
* Choose **Blueprint** (not C++)
* Click **Create** to make a new project.
  {% endstep %}

{% step %}

### Enable the Reality plugin

Once the project opens:

* From the top ribbon, click **Edit → Plugins**.
* Search for **Reality**.

{% hint style="warning" %}

#### **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.](https://github.com/AtlasXRInc/RealitySDK/releases)
{% endhint %}

* If it's disabled, click the checkbox to enable it.
* Restart the editor when prompted.
  {% endstep %}
  {% endstepper %}

#### 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**.
