Passthrough Hand TRacking

OVerview

Once you’ve finished setting up hand gesture tracking in Unity, here we’ll learn how to track hand gestures in Passthrough mode.

Requirement

1. Hand gesture tracking must already be set up

(See the Unity Hand Gesture Tracking Setup page for setup instructions)

Steps to enable passthrough

1. In Package Manager, install Unity OpenXR Meta

2. Go to Project Settings > XR Plug-in Management > Enable 'Meta Quest Feature Group' both PC and Android Tab > Fix Issues in Project Validation tab. These items should already be enabled (both PC and Android), like in the image below.

3. Select main camera in hierarchy panel > Open Environment toggle > Change background type to 'solid color', make the color black (Make sure the opacity is 0) > Click 'Add component' button > Select 'AR Camera manager'

4. In Assets > Settings > Select Mobile_RPAsset > Make sure 'Alpha Processing' is checked

5. Test in your VR headset!
