Hi everyone,
I’m trying to get the vive tracker to work in a VR game.
Following the various tutorials I created the editor shortcut -xrtrackingonly, but at that point Livelink works and I can track the movement of the vive tracker, but if I click VR preview nothing works and the view of the HMD is stuck.
if I delete -xrtrackingonly, the vr works again but livelink stops.
Do you have any ideas on how I can solve it?

Livelink is an motion capture tool for the editor. For in-game access to Vive Trackers, follow this tutorial instead : How to use Vive Trackers in UE 5.2 and later versions | Tutorial

Thanks, this works. However, I would like to decide the exact point where the tracker is applied on the mesh object.
I’d like to view the tracker in the editor so I can attach a mesh to it at an exact point.

I don’t think the above method works in the editor outside of the VR Preview. You’ll likely have to switch between using VR and Livelink by restarting the editor.

but livelink doesn’t work in unreal 5.3 and the only way to make it work is to enter -xrtrackingonly, but then the vr Preview doesn’t work

Yeah, unfortunately you’d have to switch between being able to use VR Preview and and being able to use LiveLink with -xrtrackingonly. The XR system doesn’t seem to run XR sessions outside of the VR Preview, and at least with the OpenXR plugin it means you can’t get device poses directly in the editor.
