Using Vive Tracker without headset?

[VIVE_chengnay]

Hi @_jthiessen,

How did you setup for Null HMD?

Is everything works well for HMD case?

Could you list the verions of Unity Editor, Steam VR and plugins that you installed in your project?

Thanks!

Hey @VIVE_chengnay

For Null HMD set up I adjusted 2 scripts:

1. Steam>steamapps>common>SteamVR>resources>settings>default.vrsettings

"steamvr": {
        "requireHmd": false,
        "forcedDriver": "null",
        "activateMultipleDrivers": true,

2. Steam>steamapps>common>SteamVR>drivers>null>resources>settings>defaul.vrsettings

"driver_null": {
        "enable": true,

I also removed:

"driver_null": {
	"windowX": 0,
        "windowY": 0,
        "windowWidth": 2160,
        "windowHeight": 1200,

 

The controllers appear to be oriented properly while using SteamVR with the headset.

 

Software versions:

Steam - 1696019606

SteamVR - App ID 250820, Build ID 12437937, using beta - SteamVR Beta Update

Unity Editor 2022.3.4f1

Using OpenXR 1.8.2 plugin in Unity

Hi @_jthiessen,

I tried your methods and I didn't see any issue with my controller's orientation.

Could you capture video or screenshots?

I am using VIU's UGUI sample scene and the orientation of controller in VR shows exactly the same direction as I move/rotate it.

1) Here is the controller in SteamVR Display. The controller is pointing straight to my monitor.

2) The controller is pointing to the left

3) In Unity using OpenXR the controller is pointing forward to the screen

4) In Unity pointing left

 

5) In Unity pointing up. (notice the controller canvas is backwards, as if we are looking at it from below)

Hi @_jthiessen,

May I know what is the scene you are using to play in Unity?

Could I have a copy of that and double check on my side?

Thanks!

This scene is part of the OpenXR plug-in. It is available as a sample in the package manager called "Controller".

I don't quite get what you mean by controller canvas is backwards?

Are you able to provide comparison between using HMD and without HMD? Thanks!

One more question regarding pointing left, it looks to me it is pointing to right instead of left.

This image is from Unity where I am holding the Vive controller pointing straight up and down with the trackpad facing me (as one would traditionally hold the controller). The text attached to the game object is backward.

 

This image is in Unity with me holding the controller straight up and down with the trigger facing me, (an uncomfortable, untraditional way to hold the controller). This, however, results in the text facing the correct way.

 

And you are correct about the fact that when I point the controller left, it looks as if it is pointing right. This is the problem I am having, the controllers calibration/orientation seems to be 180 degrees wrong. Again, in the photo below I am pointing my controller to the left, but it is showing it pointing right.

 

It is almost as if the angle of view in the VR View is facing the player with the controller, not the point of view of the player. Thus rendering the left and right and top and bottom orientation backwards or 180 degrees out.

vive doesnt understand they have the next wii if they get this working without the headset and easier setup
