This sample shows how to add a SceneLayer with realistic textures to a map in a SceneView. The SceneLayer is given an offset of 6 meters, to better align with the terrain.
const sceneLayer = new SceneLayer({
  portalItem: {
    id: "2342ab7928834076a1240fb93c60e978",
  },
  elevationInfo: {
    mode: "absolute-height",
    offset: 6,
  },
});The scene is made more realistic by enabling shadows and setting the lighting based on a specific time of day using the environment property of the SceneView.
view.environment = {
  lighting: {
    date: new Date("July 15, 2015 8:00:00 PDT"),
    directShadowsEnabled: true,
  },
};
