    alvr_7>
  4. In SteamVR interface, status is "Standing by". Headset and controller icons are displayed.

Your devices are ready for an XR Twin VR simulation. You can remove the Apple Vision Pro® headset at any time, even if doing so causes the ALVR in-app to close and lose the connection. When you put the headset back on, just open the ALVR in-app again.

Start XR Twin VR session#

In XRTwin, open a project with a VR Player + Hand &Finger Tracking. Click Start to launch the simulation.

Start streaming#

Equip yourself with the Apple Vision Pro®. From within the headset, open the ALVR in-app. Below the ALVR in-app's panel, wait for connection. When it appears, click the Enter button to begin streaming.
