Thread: Expressions help....

    Expressions help....

    I have a rig Im working on and having a little difficulty figuring out how to setup some expressions to handle the following..

    I have a controller that moves in the Y direction, which controls the movement of eyelids...it moves from -26mm to 26mm

    Along the eyelid are other controllers to fine tune the bones along the eyelid

    What I need is to move a controller by a certain amount as the controller 0 to 26mm...and then by another amount when the controller moves 0 to -26mm

    I've used the following expression, but it requires the controller be set to its final adjusted position, and then moves it through the whole range of movement of the main controller

    mapRange([EyeLid_Up_Ctrl.Position.Y],-0.0,0.026,0.0,Value)

    Any ideas would he helpful.
