Mixed Reality Status update

Hello,

Since 4.20 is out, I’m trying to do a vive tracker camera calibration with the Mixed Reality Capture Calibration Tool. I can make the whole configuration EXCEPT the vive tracker as a camera.

The documentation says that you can go trough the available tracking attachments with the Tab key, but nothing when I hit Tab, I only see " No Tracking Attachment ".

Any ideas?
