[Papervision3D] HotSpots on the stage

[Németh Tibor]

I'd like to put hotspots to a panorama. These spots are added children 
of the panorama called "room". Doesn't work. Why is it?

function addHotSpot():void
    {
        var hotSpot:DisplayObject3D = room.addChild(new Plane(new 
ColorMaterial(0xFFFFFF),10,10), "hotSpot" );
        var container:Sprite = hotSpot.container;
        hotSpot.x = 0;
        hotSpot.y = 255;
        hotSpot.z = 200;
        container.buttonMode = true;
        container.addEventListener(MouseEvent.MOUSE_DOWN, doPress);
    }
