Question [Or possible bug?] Cinemachine 3 Pan Tilt axis values don't respect range?

    Hey, I'm trying out the new CM3 and wanting to drive the axis value of a Pan/Tilt component directly from my player control script rather than having my input handling split up using an Input Axis Controller. One of my axes has a range defined, but it's ignored entirely when I set the value of an axis directly, i.e. 

    
cinemachinePanTilt.TiltAxis.Value += cameraInput.y;
    .

    Is this intentional? I see there's a ClampValue method, so I can work around it, but it seems like an unnecessary amount of extra code when I'd expect the clamping to happen automatically. I can't really think of a reason why you'd want to define a range on the component but not use it.

    The InputAxis struct doesn't do any processing, it's meant only to hold data (value, center, range). It's up to the axis driver to enforce the range.

    If you like, you can use the DefaultInputAxisDriver struct in your script to drive the axis based on input values. That will handle all the range enforcing, as well as accel and decel, if you want it.

    Thanks for the quick response. DefaultInputAxisDriver looks like it's doing a lot more than I need it to, so I think I'll stick with applying the range manually for now. Cheers though!
