I am trying to use the SteamVR plugin for Unity without an HMD or controllers, but with a Tracker (2018). image

I imported the camera rig but disabled the Camera and controllers. I then added an empty GameObject with Steam VR_Tracker Object script attached. See setup below. image When running in the editor, I get an OpenVR error:

[OpenVR] Could not initialize OpenVR. Error code: Init_HmdNotFound UnityEngine.Debug:LogError (object) Unity.XR.OpenVR.OpenVRLoader:Initialize () (at Library/PackageCache/com.valvesoftware.unity.openvr@411bd1ecffdc-1614121125000/Runtime/OpenVRLoader.cs:195) UnityEngine.XR.Management.XRGeneralSettings:AttemptInitializeXRSDKOnLoad () (at Library/PackageCache/com.unity.xr.management@4.0.7/Runtime/XRGeneralSettings.cs:148)

I set requireHMDto false in Steam\config\steamvr.vrsettings so I was hoping it would continue when it failed to find an HMD.

In my case Unity Editor (2021.3.18f1) immediately crashes on play if steam vr is not already open and at least one tracker visible.
