  1. Resolution Note:

    Thank you for reporting a bug to Unity.

    Our investigation indicates the issue originates from a third-party library (PhysX), rather than Unity itself. The changes required inside PhysX to change this can and will ripple in unexpected ways and as such represent too high of a risk to do. We'll track this internally and verify during future updates of the library.

    We will close this case as a third-party issue.
    Cheers,
