[away3d] About the problem of using Dae file

[Rialy]

Hi all,

Anyone can show a 3d good successfully by using the 3D model in the
google's 3d warehouse ?
I can use the Cow.dea used by PV3D to show a cow successfully, but
when i use the 3d model got from the google 3d warehouse, the 3d model
can't be display correctly.

This is my code:

package
{
        import away3d.cameras.*;
        import away3d.containers.*;
        import away3d.core.utils.*;
        import away3d.lights.*;
        import away3d.loaders.Collada;
        import away3d.loaders.Object3DLoader;
        import away3d.materials.*;
        import away3d.primitives.*;

        import flash.display.*;
        import flash.events.*;
