This topic describes how to get started with Passthrough with Meta Quest link.

Passthrough over Meta Quest Link is a feature introduced in v37 that significantly decreases the iteration time when developing passthrough-enabled apps. Passthrough over Meta Quest Link allows a passthrough-enabled app to run while using Meta Quest Link, eliminating the need to build the app on PC and deploy it to a Meta Quest device every time you test it during development. With Passthrough over Meta Quest Link, it is faster than ever to create mixed reality experiences.

Passthrough over Meta Quest Link allows you to:

Use a developer platform such as Unity or Unreal Engine to run a passthrough-enabled app by launching the app directly in the editor.
Quickly iterate during development when using the Passthrough API. (We support passthrough, keyboard, and hands functionalities, however, currently we do not support OpenXR’s XR_FB_passthrough_keyboard_hands extension).
For details about the Passthrough API, read the Passthrough API overview.

Note: Passthrough over Meta Quest Link is a developer-only feature aimed at increasing your development speed by previewing your passthrough-enabled apps while still in development. That being said, the visual appearance and performance characteristics of the experience are slightly different between running over Meta Quest Link and running on a Meta Quest device.

Prerequisites

This section outlines the prerequisites for using Passthrough over Meta Quest Link.

For details on using Link for app development, see Use Meta Quest Link for App Development.

Hardware
Using Passthrough over Meta Quest Link requires the following hardware:

A PC that meets the specifications for running Meta Quest Link
A Quest line device (for example, a Quest 2)
A compatible USB-C cable to use for Meta Quest Link. For Color Passthrough, the USB connection should provide an effective bandwidth of at least 2 Gbps. You can measure the connection speed by using the USB speed tester built into the PC app: go to Devices, select the connected device, click USB Test, and then click Test Connection. If the connection speed is low, try using a different cable and USB adapter.
Software
The essential software for using Passthrough over Meta Quest Link is:

Meta Quest build v37.0 or later
Oculus PC app with version v37.0 or later, which you can download from the Meta Quest website
Important: You must enable the Developer Runtime Features and Passthrough over Meta Quest Link toggles in the Oculus PC app by clicking Settings > Beta. The Passthrough over Meta Quest Link toggle appears only when you enable the previous toggle.

You must restart Unity after enabling the toggles.

Passthrough over Link Oculus App Settings

Note: You must sign in your developer account in the Oculus PC app and in your Meta Quest headset.

Additionally, you must use Unity version 2020.3 LTS or higher. Download the Meta XR Core SDK as a standalone package or as part of the Meta XR All-in-One SDK, version 37 or higher.

Use

Before running your app, you must enable Meta Quest Link.

To connect your Meta Quest device to your PC over Meta Quest Link, follow the instructions in How do I use Meta Quest Link to connect my Quest 2 or Quest to a computer?
For troubleshooting instructions on Meta Quest Link connection, read I’m experiencing performance issues with Meta Quest Link after adjusting my graphics preferences.
Follow these steps to test your app through Passthrough over Meta Quest Link.

Follow the Unity Passthrough API Overview to setup passthrough in your Unity project.
Rather than building and deploying the app to your headset, launch it by hitting Play in the editor while your device is connected via Meta Quest Link.
Use your device to see passthrough in your passthrough-enabled app.
Data Privacy

The Passthrough over Meta Quest Link feature is available only to developers, and can be toggled on/off through the host PC using the Oculus PC app. When toggled on, data captured from the head-mounted display’s cameras, including camera images of the physical environment, will be transmitted to and processed on the host PC. Passthrough over Meta Quest Link is off by default.

The first time you toggle on Passthrough over Meta Quest Link, the following consent modal will appear.

Passthrough over Link Unreal Postprocessing

You only need to give your consent once.

At no point during the execution of Passthrough over Meta Quest Link do the camera images that are sent to the host PC leave the host PC, except to be sent back to the headset to be displayed.

Meta Quest Link and Screenshots
Be aware that due to the privacy constraints, screenshots you take of your Passthrough application while Meta Quest Link is active may not include background passthrough content but show a dark background. If you have issues with showing Passthrough content in your screenshots, disconnect the Link cable.

This sample demonstrates how you can modify the foreground characteristics of the passthrough layer with respect to any virtual objects that are present.

Prerequisites

Before you can build the Passthrough Overlay sample, you must first complete the Passthrough Getting Started tasks. This includes the steps in the Prequisites and Configuring a Unity Project sections. You should also do the basic Passthrough Tutorial to make sure you can work with Passthrough in Unity.

Step by Step

Download the Starter Samples project from Github.
If you prefer, set up the Meta Quest Developer Hub so you can control your on-Headset application.
In the Unity Project explorer, search for the OverlayPassthrough scene. Drag it to your Hierarchy window.
Remove any other scene from the Hiearchy Window.
Save your project and your scene.
From the File menu, choose Build Settings.. to open the Build Settings window.
Make sure your headset is listed in the Run Device dropdown.
Click Add Open Scenes to add your scene to the build. Deselect and remove any other scenes from the selction window.
Click the Build and Run button to launch the program onto your headset.
