[away3d] Away3D 4, MouseEvent3D UV > HitTestRenderer issue ?

[Leonerep]

hi, i've test something simple and it doesn't work :/

(on Away3D 4.0.110915 Alpha)

i put a cube on a scene, make it interactive and test UV on Click.
3 face return a good UV.
3 face return 0,0.

pretty annoying :/

probably something wrong on HitTestRenderer ?

sample code :
        public class Maintest extends Sprite
        {
                private var _view:View3D;
                private var _cube:Cube;

                public function Maintest()
                {       if (stage) init();
                        else addEventListener(Event.ADDED_TO_STAGE, init);
                }

                private function init(e:Event = null):void
                {
                        removeEventListener(Event.ADDED_TO_STAGE, init);
                        // entry point

                        _view = new View3D();
                        _view.width = 1200;
                        _view.height = 600;

                        var bitmaptest:BitmapData = new BitmapData(128, 128, 
false,
0xff0000);
                        for (var i:int = 0; i < 4; i++)
                        {
                                for (var j:int = 0; j < 4; j++ )
                                {
                                        bitmaptest.fillRect(new Rectangle(i * 
32, j*32, 32, 32),
Math.random() * 0xffffff);

                                }
                        }
                        _cube = new Cube(new 
BitmapMaterial(bitmaptest,true,true,true));
                        _cube.mouseEnabled = _cube.mouseDetails = true;
                        _cube.addEventListener(MouseEvent3D.CLICK, 
_onCubeClick);



                        addChild(_view);
                        _view.scene.addChild(_cube);
                        addEventListener(Event.ENTER_FRAME, _render);
                }

                private function _onCubeClick(e:MouseEvent3D):void
                {
                        trace(">",e.uv);
                }

                private function _render(e:Event):void
                {
                        _cube.rotationX += .3;
                        _cube.rotationZ += .2;
                        _view.render();
                }
