Hand Rig Step
Reference joints are pre-distributed by approximation in the Hand Rig step. You can also manually reposition, mask, resize, and change the opacity of the joints.

You can use this drop-down list to set the number of the fingers
to correspond with the character model.
Currently, the number of fingers for both hands
are identical.

This pictogram shows the recommended location of the joints when you hover or pick
them. In the following example, the knuckle of the thumb is selected.

The Joint Name drop-down list shows the name of the
joint that was picked in the 3D viewport.
The desired joint can also be picked from the list.

There are two mirror buttons for mirroring the joints from right hand to left hand
and vice versa.
