Why Camera Tracking is BROKEN In Unreal Engine

to use a Vive tracker in Unreal Engine we just needed the steamvr plugin and it worked great so naturally it's been removed from the engine wait wait they still work we just need to do something a bit different yeah in Unreal Engine 5.3 you just need the open XR plugin enabled and also the openxr Vive tracker plugin and if you don't already make sure the live link and Livelink XL plugins are enabled too then close unreal Now launch steamvr and turn on your Vive tracker and just make sure your track is connected to the software open the settings and look for managed trackers in there make sure that your pose is set to camera some poses don't work some of them do but camera definitely should now the next part is really infuriating because we can't Now launch from the Epic Launcher don't stay with me here just go to the start menu and type in run and then go to Explorer and navigate to where your engine version is the path is C drive program files epic games UE 5.3 engine binaries win 64. copy that path from your Explorer and paste it into run now type this unreal editor.exe space Dash XR tracking only so click ok to run that command and it will launch unreal 5.3 open the project where you've enabled your plugins and now in unreal under the live link window you'll be able to add a new Livelink XR source and it should come in with two poses one of them would be head and one of them will be camera camera is the one we want now I'm doing camera tracking so I'm going to select my camera now and add a live link controller and then under subject representation I'm just going to select the camera pose and now when you move your Vive tracker around you should have tracking working but if you're unlucky like I was there is still a fix and it's to go back to steamvr and change the pose to something else like held in hand then try it with that it won't work then go back to steam again and change it back to camera for some reason changing the pose to something else and then changing it back to camera does fix the problem are we good
