qian 很简单的一个加载都会出问题。IOS8.4，上不行，你可以试试。
Laya3D.init(0, 0,true);
Laya.stage.scaleMode = Stage.SCALE_FULL;
Laya.stage.screenMode = Stage.SCREEN_NONE;
Stat.show();
var scene:Scene = Laya.stage.addChild(new Scene()) as Scene;
var camera:Camera = scene.addChild(new Camera(0, 0.1, 100)) as Camera;
camera.transform.translate(new Vector3(0, 0.5, 1));
camera.transform.rotate(new Vector3( -15, 0, 0), true, false);
var mc:Sprite3D = scene.addChild(Sprite3D.load("res/mod5_13.lh")) as Sprite3D;
