in pre v4.24 motion controller inputs are generic so they can be used with any controller. It created issues when trying to build projects to be used by both vive and oculus, and you’d have to re-assign controls at runtime depending on users hardware. So now the inputs are changed to be hardware specific which makes it a lot easier to build inputs for both sets of hardware. Now when searching for inputs, search for “oculus” or “vive” instead of “motion controller”.
Also the "face button"s were renamed to match hardware button maps, so oculus uses ABXY instead of face button 1234, etc.
