IsMatrixValid (matrix) error spam while testing SteamVR in Unity 5

Unity Engine

To preface: I am somewhat of a beginner when it comes to Unity and VR. I borrowed a friend of mine’s Vive in order to test it out before trying to start a VR project in Unity 5.5.

So i made a new project in Unity with SteamVR already running and I have already defined my play space and the headset, towers and controllers are all being sensed (green). Firmware is also all up to date. I downloaded/imported the SteamVR Unity plugin (which now resides under Assets). I went to the Assets>SteamVR>Examples and loaded up a scene. When i played the scene it spammed me with the IsMatrixValid (matrix) error and my controllers would not appear. I could move my head and look around just fine though. When i pressed the menu button on the controllers though to bring up the the menu, my controllers would appear just fine and function correctly. I also noticed that the controller Gameobjects were dimmed out like they were not functioning, the scripts within them were also dimmed out.

I have been patrolling this forum for a while and tried a few things and found some half answers, but nothing has worked for me so far which leads me to this post.

I can clarify any details if need be. Any and all help would be appreciated!

I had something similar happen. The view was always fixed in a direction (not facing the monitor as expected). It turned out I had a hardware missed connection and the system wasn’t able to read the heading. The matrix error went away as soon as I disconnected everything and reconnected.

The headgear for me works just fine, the controllers are the problem, they are invisible in unity, but visible all other times. Your method unfortunately did not work for me, thanks though, I had not tried that yet.
