Character Hand Mapping Methods

Motion LIVE 2D allows for mapping hands between the virtual characters and the real-human actors. You can determine if you want to use the actor's one hand to control one hand, both hands of the virtual character, or control its hands in mirror mode with the mapping features.
After the hand data source is decided, you can also change the default palm and elbow facing with ease. All of these settings can be saved as custom mapping profiles.

Hand Mapping Methods

Click these two buttons to choose your hand tracking data for the character's left hand and right hand by cycling through the different hand mapping methods. Alternatively, you can select a method from the drop-down list of the button. ( Watch Video )

: Controlled by none of your hand.
: Controlled by your right hand.
: Controlled by your left hand.

Mirror Mode for Leap Motion Controller

By default, you can use your hands to control the character's hands in mirror mode in Motion LIVE 2D. That is, when you are facing the display, the gesture data is set to opposite hands to control the character's hand in mirror mode.
