Remove objects from Papervision3D scene

Hi!

Does anyone know how to remove objects like Plane from Papervision 3D scene? I have tried container.scene.removeChild(plane); but it gives me an error like this:

“1119: Access of possibly undefined property scene through a reference with static type flash.display:Sprite.”

So what I’m understanding is that I can only use removeChild() with Sprite objects (and maybe MovieClips) but I cant remove objects that are part of Papervision scene?
