[0]LayaAir2.13.0 camera如何设置透明背景？

 let _config = new Config3D();

_config.isAlpha = true;

//根据IDE设置初始化引擎		

if (window["Laya3D"]) Laya3D.init(GameConfig.width, GameConfig.height, _config);

else Laya.init(GameConfig.width, GameConfig.height, Laya["WebGL"]);

Laya.stage.bgColor = "none";

camera.clearFlag = Laya.BaseCamera.CLEARFLAG_SOLIDCOLOR;

camera.clearColor = new Laya.Vector4(1, 1, 1, 0);
