3. Create a new project in Unity, making sure to choose a version above 2021.
4. Select the 3D template for the project.
5. Name the project (e.g., "Quest 3 XR App") and create the project.

Step 2: Enabling XR in the Project

1. Go to Edit > Project Settings > XR Plugin Management.
2. Click on "Install XR Plugin Management."
3. Enable Oculus for both PC and Android under the plugin providers.

Step 3: Choosing Oculus Integration or Unity XR Interaction Toolkit

1. Decide between Oculus integration and Unity XR Interaction Toolkit based on your project requirements.
2. For Oculus integration, add the Oculus Integration package from the Unity Asset Store to your project.

Step 4: Project Setup for Quest 3

1. Use the Oculus Project Setup Tools to ensure the project is set up correctly for Quest 3.
2. Switch the platform to Android in File > Build Settings.

Step 5: Setting Up the Camera Rig and Controllers

1. Replace the main camera with the OVR Camera Rig in the project hierarchy.
2. Add OVR controllers and hands to the player by dragging the OVR controller and OVR hand prefabs under the left and right controller and hand slots.

Step 6: Adding Passthrough Feature

1. Create an empty GameObject and name it "Passthrough Component."

2. Adjust the cube's position, rotation, and scale to make it visible in the camera view.
3. Test the game in the Unity Editor with Oculus Link enabled.

Step 8: Building and Running the Project on Quest 3

1. Ensure the scene is added to the build settings.
2. Click on Build and Run to export the game to Quest 3.
3. If the Quest 3 is in developer mode and connected via USB-C, Unity should build the game to the device.

Step 9: Finalizing the Quest 3 Mixed Reality Game
