The Unity packages that support XRAn umbrella term encompassing Virtual Reality (VR), Augmented Reality (AR) and Mixed Reality (MR) applications. Devices supporting these forms of interactive applications can be referred to as XR devices. More info
See in Glossary development fall into two broad categories:
The Unity XR plug-in framework provides the basis for XR development in Unity. You can add support for an XR device to a project by installing and enabling the relevant XR plug-in. You can add or remove plug-ins to the project at any time.
See XR Project set up for instructions on how to add XR plug-ins to your project using the XR Plug-in Management system.
Unity supports the following XR plug-ins:
| Plug-in | Supported devices |
|---|---|
| Apple ARKit | iOS devices |
| Google ARCore | Handheld Android devices |
| Microsoft HoloLens | HoloLens, HoloLens 2 |
| Windows Mixed Reality | Microsoft supported package for HoloLens and Windows Mixed RealityMixed Reality (MR) combines its own virtual environment with the user’s real-world environment and allows them to interact with each other. See in Glossary headsets (various manufacturers). Note: This package is deprecated in Unity 2021+. Microsoft recommends using the OpenXR plug-in instead. |
| Magic Leap | Magic Leap 1. Note: Magic Leap 2 is supported by version 7.0+ of the Magic Leap package, which is available in Unity 2022+. |
| Oculus | Oculus Rift, Meta Quest 2, Quest Pro |
| OpenXR | Any device with an OpenXR runtime, including Meta headsets, Vive headsets, Valve SteamVR, HoloLens, Windows Mixed Reality, and others. |
| PlayStation VR (available to registered PlayStation developers) | Sony PS VR and PS VR2 devices. See PlayStation Partners for more information. |
See XR Platform System Requirements for system requirements for developing XR projects in Unity.
Notes:
Unity’s XR packages build on the XR plug-in framework to add additional application-level features and developer tools.
The XR packages include:
| Package | Description |
|---|---|
| XR Plug-in Management | Adds Project SettingsA broad collection of settings which allow you to configure how Physics, Audio, Networking, Graphics, Input and many other areas of your project behave. More info See in Glossary for managing the platforms and plug-ins used by a Unity XR project. See Project setup for information about managing XR plug-ins. |
| AR Foundation | Provides cross-platform AR features, such as plane detection, meshing, and object tracking. Required for developing AR applications with the Unity XR packages. |
| XR Interaction Toolkit | Provides interaction components for adding controller-based interaction and manipulation, UI(User Interface) Allows a user to interact with your application. More info See in Glossary interaction, and movement. Supports VR, MR, and AR. |
| Unity Mars | Provides components and tools for adapting AR content to the user’s surroundings. For example, it supplies a standard way of querying the environment to find suitable locations for adding your digital content to the sceneA Scene contains the environments and menus of your game. Think of each unique Scene file as a unique level. In each Scene, you place your environments, obstacles, and decorations, essentially designing and building your game in pieces. More info See in Glossary. Requires a license that includes Unity Mars. See Unity Mars for information about license requirements. |
| XR Core Utilities | Contains software utilities used by other XR plug-ins and packages. Typically installed in your project as a dependency of other XR packages. |
| XR Legacy Input Helpers. | Contains software utilities related to XR input. This package is being phased out, but is still installed as a dependency by some XR packages. |
