Required packages

The AR Foundation package contains interfaces for AR features, but doesn't implement any AR features itself. To use AR Foundation on a target platform, you also need a separate provider plug-in package for that platform. A provider plug-in is a separate package containing AR Foundation feature implementations for a given platform.

Unity officially supports the following provider plug-ins with this version of AR Foundation:

AR Platform	Provider plug-in	Version
Android	Google ARCore XR Plug-in	6.1
iOS	Apple ARKit XR Plug-in	6.1
HoloLens 2	OpenXR Plug-in	1.8

To use AR Foundation on a device, you must install at least one provider plug-in, either from the Package Manager or by going to Project Settings > XR Plug-in Management as shown below.

XR Plug-in Management

Note

To use additional ARCore functionality such as Cloud Anchors, install Google's ARCore Extensions for AR Foundation.

Provider project settings

Some provider plug-ins require that you set specific project settings for AR to function properly. See their documentation for specific instructions:

Provider plug-in	Setup instructions
Google ARCore XR Plug-in	Project configuration
Apple ARKit XR Plug-in	Project configuration

Third-party plug-ins

It is possible to develop custom provider plug-ins for AR Foundation. If you are using a third-party provider plug-in, see your plug-in documentation for more specific instructions regarding installation and use.
