[OpenXR + HandTracking] Random ensure NewTransform Warning.

Hi,

I am working on Mixed Reality project in Unreal 5.4.4, I am using OpenXR and HandTracking(No Physical Controllers). My Head set is Varjo XR-4 Focal Edition.

My Setup includes:

  • A Pawn with a UMotionControllerComponent and it’s tracking source is set to EControllerHand::Left.

  • No Manual Transform Setting for UMotionControllerComponent.

  • An Actor that contain a widget component for UI.

  • That Actor at attached to UMotionControllerComponent at runtime. No Manual Transformation being Applied to this UMotionControllerComponent. (BTW I’m also getting this warning log even without this actor attachment)

Issue:

  • At Random interval(not at the start) I am getting this warning log.

  • This issue is appeared internally when the unreal is trying to apply component’s transform, but it receives an invalid number.

  • The issue is not tied to a specific event.

  • More frequent on one PC/Headset as compare to the other, even if the build is same.

I Have Tried:

  • Validate UMotionControllerComponent Before using it.

  • Disabled Low latency updates.

  • Custom Motion Controller Component.
