hi guys, i got 2 questions:
1, i load file (3ds / or dae) into stage but i only wanna display the model as wireframe (even set color for the lines) no material. but now nothing appear on the stage as i did not set material for the model in 3dmax, so how can i show the wireframe?
2, on my stage, there is a background (sprite) behind the view3d instance:
  Main.as -> Main extends Sprite //the document class
  addChild(new BgSprite());
  addChild(new MyStage3D());  //MyStage3D extends View3D
  so i think the BgSprite should behind the MyStage3D? but now i cannot see the MyStage3D as the ‘top layer’ is BgSprite! why??
please help… 

ah, i use away3d 4.1 alpha.
