DAE模型帖图，图片变形问题！请帮忙解决 ninja (2010-05-24 18:52:51)

以下是我Flex下BP500.as文件的代码．.dae模型帖图后在自转过程中图片回变形．不知道什么原因啊．

   init3d();
  }
  
  private function init3d():void{
   scene = new Scene3D;
   camera = new Camera3D;
   pviewport = new Viewport3D(510, 300, true, true);
   renderer = new BasicRenderEngine;
  
   this.addChild(pviewport);
   getLoadFile();
  }
  
  private function getLoadFile():void{
   
   daeFile = new DAE(true, "strong", true);
   
   var _mt:MaterialsList = new MaterialsList({mt:new FlatShadeMaterial(mylight, 0xffffff), all:new BitmapFileMaterial
   ("dae/BP500_UV.jpg")});
   
   daeFile.load("dae/BP500.DAE", _mt);
    //camera.z =daeFile.z ;
                //camera.focus = 20;
                //camera.far = 500
   renderer.renderScene(scene, camera, pviewport);
   daeFile.addEventListener(FileLoadEvent.LOAD_COMPLETE, onLoadComplete);
   
  }
  
  private function onLoadComplete(e:FileLoadEvent):void{
   scene.addChild(daeFile);
   
   renderer.renderScene(scene, camera, pviewport);
   stage.addEventListener(Event.ENTER_FRAME, enterFrame_rander);
  }
  
  private function enterFrame_rander(e:Event):void{
   daeFile.rotationY += 2;
   daeFile.scale = 4;    
   renderer.renderScene(scene, camera, pviewport);
  }
 
 }
}

	ninja (2010-05-25 15:38:17)	问题解决了： 问题根源说明：跟模型切的段有关系，要象让模型不变形就要多切段．但段太多会影响flash速度．建议控制在200以内（我还是初学，可能说的不对，这只是个人的学习总结）
	DDM君 (2010-05-26 22:00:00)	呵呵，说的很对，总结的很棒呢，继续加油~
