Hello everyone.

The Mixed Reality Forums here are no longer being used or maintained.

There are a few other places we would like to direct you to for support, both from Microsoft and from the community.

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.

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, or in our Microsoft Tech Communities forums at https://techcommunity.microsoft.com/t5/mixed-reality/ct-p/MicrosoftMixedReality.

And always feel free to hit us up on Twitter @MxdRealityDev.

holographic tracking state lost

Hi,this is the first post :)

Assertion failed on expression:'IsMatrixValid(matrix)'
holographic tracking state lost. New State:1

Connected successfully but when I played the scene, all crashed.
The console showed above.

Unity: 5.6.0f3
I used the Wireless LAN Card to connect the computer and Hololens.

BTW, there is a Javascript on the scene. Show as below.
#pragma strict
function Start (){
function Update(){

I'm not sure the problem is about Microsoft or Unity.
Thanks for any suggestion.



  • I think your code is off but I don't tend to write javascript so perhaps I am wrong.

    In C# it would be something along the lines of:

    Or if you really wanted to expand that Vector then maybe:
    transform.Rotate(new Vector3(0,1*Time.deltaTime,0),space.self);

    You could replace the 1 with a 25 but that seems like a large amount of rotation. Try this first before ramping it up.


  • Nevermind, looks like your code is fine. Maybe just try a 1 instead of 25 first.
