I am able to rotate a mask while it affects an object on a motion path: See the Pen WNEXwNE by geedix (@geedix) on CodePen   And I can tween a mask without a motion path, but I haven't been able to tween a mask on its own motion path. Possible?  .  thanks See the Pen BadmLza by geedix (@geedix) on CodePen
