 Bend fingers in response to VR Controller bending input. Each finger can be controlled individually or not at all. Each finger is defined as a single bone chain. Bending can be fine tuned using an animation move. Bend fingers in response to VR Controller bending input. Each finger can be controlled individually or not at all.

 +Wrist bone. Click on the label or the combo box to activate bone selection mode. Click in the preview window on a bone to select it. The selected bone is marked in red. Assigning wrist bone is useful to improve tracking quality on finger tracking without using a controller. VR runtimes tend to apply a rotational offset to the wrist not present in the reported input device causing the captured hand to have an unwanted twist. For controllers with hand tracking estimation this is usually not required.

 +====== Wrist Rotation ======

 +Rotation of wrist bone for use with non-animation-move based finger tracking. This rotation indicates the direction of the hand to match the actor hand. The X-axis (<fc #ff0000>red axis</fc>) points towards the thumb (hence upwards). The Z-axis (<fc #0000ff>blue axis</fc>) points towards the finger tips (hence away from the body).
