Hello everyone.

We have decided to phase out the Mixed Reality Forums over the next few months in favor of other ways to connect with us.

The first way we want to connect with you is our mixed reality developer program, which you can sign up for at https://aka.ms/IWantMR.

The plan between now and the beginning of May is to clean up old, unanswered questions that are no longer relevant. The forums will remain open and usable.

On May 1st we will be locking the forums to new posts and replies. They will remain available for another three months for the purposes of searching them, and then they will be closed altogether on August 1st.

So, where does that leave our awesome community to ask questions? Well, there are a few places we want to engage with you. For technical questions, please use Stack Overflow, and tag your questions using either hololens or windows-mixed-reality. If you want to join in discussions, please do so in the HoloDevelopers Slack, which you can join by going to https://aka.ms/holodevelopers. And always feel free to hit us up on Twitter @MxdRealityDev.

render hologram in tracking loss status

To render a hologram as head-locked, I was using the following code:
Transform cameraTransform = Camera.main.transform;

    interpolator.SetTargetPosition(cameraTransform.position + (cameraTransform.forward * Distance));
    interpolator.SetTargetRotation(Quaternion.LookRotation(-cameraTransform.forward, -cameraTransform.up));

But when we are in a tracking loss status, it seems that the "Camera.main.transform" variable will not be available to use. I understand there are some codes to determine we are in the tracking loss status as the following:
void Update()
{
switch (UnityEngine.VR.WSA.WorldManager.state)
{
case PositionalLocatorState.Active:
// handle active
break;
case PositionalLocatorState.Activating:
case PositionalLocatorState.Inhibited:
case PositionalLocatorState.OrientationOnly:
case PositionalLocatorState.Unavailable:
default:
// only rotational information is available
break;
}
}

But what should I do in the cases of tracking loss to render a hologram in front of me? Looking forward to your help!
