我修改了咱们的示例代码，现在会显示模型，但是没有单体化效果，有大神可以帮我看看吗？
<script>
function onload(Cesium) {
var viewer = new Cesium.Viewer('cesiumContainer');
var scene = viewer.scene;
scene.lightSource.ambientLightColor = new Cesium.Color(0.65, 0.65, 0.65, 1);

var dataSourceName = '查询'; // 数据源名称
var dataSetName = '兴趣点'; // 数据集名称
// 加载倾斜摄影图层
var promise = scene.addS3MTilesLayerByScp('http://localhost:8090/iserver/services/3D-ChaXun/rest/realspace/datas/Combine/config', {

});
promise.then(function (obliqueLayers) {
camera.setView({ // 先定位，开始渲染定位区域的倾斜
