Using Hand Tracking provided by MRTK3, how can hand patterns be hidden at runtime?
By setting the "Model Prefab" of the "XR Controller" components of the GameObjects "MRTK RightHand Controller" and "MRTK LeftHand Controller" to "none", you can hide the hand models during the Play phase in the Game window; But in ML2 they are still visible and if you want to record a video through the ML2 itself, black patterns are visible that are not perfectly aligned with the hands which disturb the vision.
