设置普通贴图、法线贴图、高光贴图

// 加载漫反射贴图 法线贴图 高光贴图
protected loaderAsset() {
    var loader: egret3d.QueueLoader = new egret3d.QueueLoader();
    loader.addEventListener(egret3d.LoaderEvent3D.LOADER_COMPLETE, this.onAssetComplete, this);

    loader.load("resource/doc/materail/brick-diffuse.jpg");
    loader.load("resource/doc/materail/brick-normal.jpg");
    loader.load("resource/doc/materail/brick-specular.jpg");
}

// 
protected onAssetComplete(e: egret3d.LoaderEvent3D) {
    var loader: egret3d.QueueLoader = e.target; 
    var plane: egret3d.Mesh = new egret3d.Mesh(new egret3d.PlaneGeometry(300, 300));
    this.view.addChild3D(plane);

    plane.material.ambientColor = 0xcccccc;
    var p0: egret3d.PointLight = new egret3d.PointLight(0xffffff);

    // 设置点光源的坐标
    p0.y = 50;
    p0.z = 200;

    this.lights.addLight(p0);

    plane.material.lightGroup = this.lights;

    // 设置漫反射贴图
    plane.material.diffuseTexture = loader.getAsset("resource/doc/materail/brick-diffuse.jpg");

    // 设置法线贴图
    plane.material.normalTexture = loader.getAsset("resource/doc/materail/brick-normal.jpg");

    // 设置高光贴图
    plane.material.specularTexture = loader.getAsset("resource/doc/materail/brick-specular.jpg");
}

设置cutAlpha

// 把一张透明贴图 cut alpha
protected useCutAlpha() {
    var plane: egret3d.Mesh = new egret3d.Mesh(new egret3d.PlaneGeometry(300, 300));
    this.view.addChild3D(plane);
    plane.material.diffuseTexture = this.queueLoader.getAsset("resource/doc/materail/cut.png");
    plane.material.cutAlpha = 0.5;
}

---

设置贴图双面渲染

// 把一张透明贴图 cut alpha
protected useCutAlpha() {
    var plane: egret3d.Mesh = new egret3d.Mesh(new egret3d.PlaneGeometry(300, 300));
    this.view.addChild3D(plane);
    plane.material.diffuseTexture = this.queueLoader.getAsset("resource/doc/materail/cut.png");
    plane.material.cutAlpha = 0.5;

    // 设置双面渲染
    plane.material.bothside = true;
}
