Remember to disable Support OpenGL ES3.2 under Android ->Build. Quest projects will not work with that option ticked. Make sure to run the test under “Meta XR Performance Window” and select Mobile as your target platform. Also Remember to package the project for oculus using the “Package for Meta Quest devices” option.

Ensure that your project is compatible with the Android guidelines

When you package your quest device do not forget to tick the “Package for Meta Quest Devices”. Under “Android” -> “Advanced APK Packaging” -> “Package for Meta Quest Devices” package_for_quest

If you see that your project opens as a “window” application inside the quest, it is a good indication that you forgot to check this box.

Try to deploy a simple level to your headset

Try and build the project and deploy it to your headset.

Download and extract AR51 Unreal Plugins into the Plugins folder

Your plugins folder should look like this: plugin_folder Restart the editor to enable the plugin.

Make sure your VrPawn object uses “stage tracking”

Either create a new VRPawn object (using these instructions) or edit the provided VRPawn Blueprint. Make sure that your tracking space is set to “Stage” tracking_set_to_stage

In AR51 Blueprint, select “Oculus Quest” as the platform type

From the Details panel, under “General” you should see a field “Platform”. Please select “Oculus Quest” select_platform_type

Make sure you have enabled Meta’s Hand support

  • “Hand Tracking Version” works better with V2.

Be sure to enable “Developer runtime features” on the “Oculus PC app”

Without enabling this option you might not be able to move your hands on a tethered app and also in “VR preview” mode

Open the “Oculus” PC application. Under Settings -> Beta, enable “Developer runtime features”. enable_developer_option_on_oculus_pc_app

In a tethered deployment - enable “Start in VR”

Before deploying to a tethered application (PC VR app), be sure that you project is set to start in VR. In Unreal-Engine, under “Project Settings” -> “Project Description” enable “Start in VR”.
