Cinemachine input axis controller orbit scale

I wonder how it controls the orbit scale. I don’t get any difference when the mouse scrollwheel.
I notice that it has input.

Look at the Radial Axis in CinemachineOrbitalFollow. Put something nontrivial in the Range (by default it’s 1…1, which will do nothing).

Thank you. This is the approach for controlling the zoom of the 3rd person camera that I want. I am confused about the Cinemachine Input Axis Controller because I am new to this and am following the document.

It’s the controller’s job to read user input and apply it to the Value setting of the axis it’s controlling. Value is limited to the Range setting.
