It is now recommended to use the OpenXR instead of SteamVR plugin since UE5.1
However, I am running into some problems.
I can’t find anything on how to connect VR trackers (such as the Vive trackers) to livelinkXR (or anything else for that matter) using OpenXR.
Not sure if there is any readily available way of using trackers in 5.1. They require an extra OpenXR extension that is not implemented in the stock plugin.
