【iPortal】三维地球保存的场景在大屏加载会随着时间改变模型亮度，如何常亮

Answer 1

【解决办法】使用低代码编辑器设置场景光照: 如: et scene = $WebScene_0.viewer.scene // 01设置环境光的强度 scene.lightSource.ambientLightColor = new Cesium.Color(0.65, 0.65, 0.65, 1); // 添加光源 var position1 = new Cesium.Cartesian3.fromDegrees(116.261209157595, 39.3042238956531, 480); //光源方向点 var targetPosition1 = new Cesium.Cartesian3.fromDegrees(116.261209157595, 39.3042238956531,430); var dirLightOptions = { targetPosition: targetPosition1, color: new Cesium.Color(1.0, 1.0, 1.0, 1), intensity: 0.55 }; directionalLight_1 = new Cesium.DirectionalLight(position1, dirLightOptions); scene.addLightSource(directionalLight_1);
