Head tracking stops when switching scenes depending on skybox/lighting about unity-webxr-export HOT 9 CLOSED

Yeah, tested it a few more times to make sure. I'll put up a demo scene on github pages soon as an example

I added a cube to the Desert scene. When the cube is touched by a hand, the scene switches to "Desert 1". This scene is the same as Desert with the only change being the skybox. Tested with a Vive on Firefox, the head tracking freezes (the hands still track).

On another note:
If you touch the cube in the "Desert 1" scene, it will take you back to the "Desert" scene, though it will create the duplicate camera glitch. While this second part isn't really a bug or the issue I'm referencing, it might be worth adding some type of singleton behavior to the camera rig. ex:

namespace WebXR {
public class XRCamera: MonoBehaviour {
public static XRCamera current = null;

void Awake() {
  if (null == current) {
    current = this;
  } else if (current != this) {
    Destroy(gameObject);
  }
}

}
}

(I can't figure out how to format that code with markup...) But this way there can't be duplicate XR camera rigs.

Just did a little testing and figured out changing the "Awake()" function in "WebXRManager.cs" to this will fix the camera duplication thing:

private void Awake()
{
  Debug.Log("Active Graphics Tier: " + Graphics.activeTier);
  if (null == instance) {
    instance = this;
  } else if (instance != this) {
    Destroy(gameObject);
  }

  if (instance.dontDestroyOnLoad)
  {
    DontDestroyOnLoad(instance);
  }
  xrState = WebXRState.NORMAL;
}

It sounds weird. Are you sure you don't have existing cameras in those scenes?

from unity-webxr-export.

Sure. Upload a project (preferably a fork of this repo), and I'll check it

Thanks!

Regarding the singleton, yes, it should be in the WebXRManager.

I'm trying to think of a good way to generalize all the Rig, so it would be easier to implement it in current AR/VR rigs.
Would like to hear what you think.
Which XR APIs are you working with in general(Not for WebXR) to get the Camera and Controllers poses?

from unity-webxr-export.

What do you mean by generalize? Do you mean break it down into smaller prefabs that can create a rig when put together? I've been working on a hand interaction system that is more generalized, though not sure how much you would like it since it uses parenting instead of fixed joints.

Also when you say XR API do you mean the OVR Integration and SteamVR packages? I use those a fair amount but I've been using your exporter more recently because it is so much cooler/better to build stuff for the web due to accessibility.

Sorry, but I didn't get to check it yet. Did adding the Destroy method on Awake solves the issue?

Reading this issue MozillaReality/unity-webxr-export#423
I guess it's the same, and by the look of it, it might already fixed in this repo in #65

I'm closing this issue, as there wasn't a comment for a long time. If it still happens please comment.
