I would like to know how I would go about making slider controls for a rig. I want it to be like a nurbs curve square on a line that i can move up and down or left and right (depending on line orientation) and it will rotate a joint on my rig the more i move it. Sort of like equalizer buttons on a stereo but to control my rig. I have eyebrows and a jaw that I need to control in this manner. The eyebrows will need to have the slider start in middle and move up and down which will move eyebrows up and down (questioning/sad and angry) and the jaw will start the slider at the bottom and move up to open it. I really appreciate any help, especially if it’s prompt.
