Butterworth curve filter for Max



Does anyone know if there’s a Butterworth filter for animation curves in Max like this one here for Maya?

It was a HUGE time saver for me in Maya when working with baked animation data. Max’s Smooth Curve function is kind of a joke, usually does more damage than it does help.

Has anyone ported this over to Max or know of any scripts similar? I’ve searched but haven’t found anything for animation curves.
