Hand poses are preconfigured configurations of the hand and fingers which can be used to show and mix realistic hand poses.
Humanoid Control provides 5 preconfigured hand poses: open, pointing, closed, grabbing and thumbs up. More hand poses can be added using the Add New Pose button.
Hand poses can be selected and mixed using the sliders or by using the function SetHandPose(HandPose pose, float weight). All poses will be mixed using averaging. The total of all hand poses weight will always be 1. Note that this differs from blend shapes which are combined in an additive way.
If a new hand pose is set with a weight smaller than 1, the weight for the old hand pose combination is decreased by ratio such that the total weight is 1 again.
Poses can be edited in the scene view by enabling Set for a pose.
Reset All can be used to reset all hand bones back to the predefined pose or to the open pose for custom hand poses. Reset Bone is only available when a bone has been selected in the Scene View and can be used to reset a single bone.
In the scene view you will see handles for each bone which can be used to rotate each bone to the desired pose. An handle can be selected by clicking on it
This will show the name of the bone an an rotation tool which enables you to rotate the bone.
When Set is deselected, the altered hand pose is stored and can be used.
