Issue having thigh mask layer rotate at different speeds (2 Viewers)

[Boginator97]

I'm trying to make a bottoms mod. I've gotten the mod fairly functional, but I want to use a mask layer to stop the right thigh from protruding above the waist while allowing a wide range of motion. I got the mask layer to hide the right thigh, but it rotates with the thigh. I tried using this code from Faceless...

...in the main settings file, but the mask layer continues to rotate with the thigh.

import flash.events.Event;

addEventListener(Event.ENTER_FRAME, rotateMask);

function rotateMask(e:Event) {
    bottoms.rightThigh.thighMask.rotation = bottoms.rightThigh.rotation/500;
}
