(Solved) Is VR mirrored hand animation breaking?

General Feedback & Requests

The left hand animation stops working when I toggle the “Mirror” boolean value in B_MannequinsXR with my mouse cursor. I’m using the default (Games/Virtual Reality) project. These are the steps to duplicate the issue in UE Version 5.3.2-29314046

  1. Launch the project from the editor using the “VR Preview” mode.
    *Left and right hand animations work as expected when you touch the controller buttons.

  2. Open “B_MannequinsXR” blueprint and with your mouse cursor, toggle the default value of “Mirror” on then off, in the details panel of the blueprint.

  3. Launch the project again in the “VR Preview” mode.
    *Left hand animations no longer play when you touch the left controller buttons.

If you save assets unreal thinks you changed from doing step 2, then your left hand animations will remain broken and won’t play when you reopen the project. If you don’t save the assets unreal thinks you changed in step 2, then the left hand animations will work after you reload the project in the editor.

Is this expected behavior or did I find a bug? Toggling the “Mirror” manually on then off should essentially not change anything as far as I know.

Figured out this is not a bug and is intended behavior. An instance of B_MannequinsXR is used as the left and right hand in VRPawn. The left hand instance has to have the default property of “Mirror” set to True and the Right hand set to False manually in VRPawn.

If you change the “Mirror” value in the B_MannequinsXR blueprint, it will set both the left and right hand instances in VRPawn to either true or false which is what caused my issue.
