[Papervision3D] materials dont change when using collada.replaceMaterialByName

[ahalim kara]

Hi all,

I am trying to change material of a loaded collada object with collada.replaceMaterialByName function. But it doesnt change the texture, still uses the png file loaded for collada. If i use collada.getMaterialByName("mat0").copy(new ColorMaterial(0)); it works however Flash crashes. Here is my code:

package org.ahk //this is a document class for a blank fla file
{
    import flash.display.MovieClip;
    import flash.events.Event;
    import flash.utils.setTimeout;
    
    import org.papervision3d.events.FileLoadEvent;
    import org.papervision3d.materials.ColorMaterial;
    import org.papervision3d.objects.parsers.Collada;
    import org.papervision3d.view.BasicView;
    
    /**
    * ...
    * @author Abdulhalim Kara
    */
    public class Main extends MovieClip
    {
        private var basicView:BasicView;
        private var cow:Collada;
        
        public function Main()
        {
            basicView = new BasicView(640, 480, false);
            cow = new Collada("http://papervision2.com/wp-content/downloads/dae/cow.dae");
            cow.addEventListener(FileLoadEvent.COLLADA_MATERIALS_DONE, matsLoaded);
            
            basicView.scene.addChild(cow);
            basicView.camera.z += 400;
            
            addChild(basicView.viewport);
        }
        
        private function matsLoaded(e:FileLoadEvent):void
        {
            cow.replaceMaterialByName(new ColorMaterial(0), "mat0");
            //cow.getMaterialByName("mat0").copy(new ColorMaterial(0));
            trace(cow.materialsList());
            
            basicView.startRendering();
        }
    }
}
