I have an object that I'd like to use an FFD modifier on to have it open and close (the shape is basically an umbrella) When I try to wire the FFD to the slider I get this error: "Unable to convert (1.1.1) to type: Float." I understand this is because you can't wire two different types of controllers to each other, my question is, does anyone have any other ideas how I can control the opening/closing without manually animating the control points on the FFD?
Any help is appreciated.
