As I said, we are using the example that comes with the package.
The code of the tutorial is the same but incomplete, while the code of the example inside the package is complete.
There, in the "else" there is code to hide the gameObject.
The value of "allowUntrackedPose" does not matter for the case that I say that is to show or hide the gameObject, that variable is only used in the logic of move/rotate each joint.
The basic problem is that the 4 variables (posValid, posTracked, rotValid, rotTracked) return incorrect values for the case of "hide" the hands, it seems that it still believes that they are in sight.
My concern is that underneath it uses OpenXR APIs and that the problem goes beyond some focus 3 update, software on Windows from HTC, etc that causes something to malfunction.
Can you please test this case? Several of us have check it on different equipment, focus 3, etc.
