[Papervision3D] yaw getting reset when tweening with Papervision3D AS3

[Paddy Keane]

Hi Guys,

I'm having problems when tweening properties of a papervision3d DisplayObject3D. It seems to reset the 'yaw' value ;( Anyone have any ideas how I could fix this?

Example:
http://www.darklump.co.uk/experiments/papervision3d/as3/tweenerTest.html

Source:
http://www.darklump.co.uk/experiments/papervision3d/as3/tweenerTest.fla

click on stage.
Result: when tweening starts the sphere's yaw is reset causing it to jump to a different position. I'm pretty new to papervision3d and tweener. I have an inkling that the transform matrix of the DisplayObject3D is getting wiped. Can anyone help?


[CODE]

import flash.events.Event;

import caurina.transitions.Tweener;

var canvas:Sprite = new Sprite();
addChild(canvas);
canvas.x = stage.stageWidth*.5;
canvas.y = stage.stageHeight*.5;

var scene:Scene3D = new Scene3D(canvas);

stage.addEventListener(Event.ENTER_FRAME, handleEnterFrame); scene.container.stage.addEventListener(MouseEvent.MOUSE_DOWN,mouseDownEvent);

var sphereContainer:DisplayObject3D = new DisplayObject3D("sphereContainer");

var clr:ColorMaterial = new ColorMaterial(0x00ff00);
var sphere:Sphere = new Sphere(clr, 200, 10, 10);
sphere.x = 1250;
sphereContainer.addChild(sphere);

// rotate around center axis
sphereContainer.yaw(90);

scene.addChild(sphereContainer);

var camera:Camera3D = new Camera3D(sphereContainer);

camera.z = -1000000;
camera.y = 500000;
camera.zoom = 1500;

function handleEnterFrame(e:Event):void
{
	scene.renderCamera(camera);
}

function mouseDownEvent(e:MouseEvent):void {
	Tweener.addTween(sphereContainer, {scale:.1, y:-2000, time:2, transition:"easeoutquad"});
}
