Prevent Unity from starting SteamVR through code

Hi !
I'm trying to prevent unity from starting SteamVR on start for an application that could be using SteamVR (but not necessarily). I tried various things :
SteamVR_Settings.instance.autoEnableVR = false;
XRSettings.LoadDeviceByName("");
XRSettings.enabled = false;

But everytime, SteamVR starts and OpenVR says
XR: OpenVR Error! OpenVR failed initialization with error code VRInitError_Init_HmdNotFoundPresenceFailed: "Hmd Not Found Presence Failed (126)"!
I do not know if the start of SteamVR is linked to OpenVR trying to initialize or not

If possible, I would like to have code that work at runtime, not changing the parameters in the editor

 

Likely there is a setting somewhere that causes auto-initialization, you would need to turn that off, then conditionally start it up yourself.

You might have more luck with this question over in the AR/XR/VR group on this biard, where folks use these APIs regularly.

 

Good point, I'll try that ! thanks !
