Lights

Light sources are important to give your scene an realistic appearance and make them look nice. Adding lights also allows to create shadows. Currently, we support PointLight, DirectionalLight and SpotLight. All of them derive from the ShadowLight which defines the following properties (but can’t be instantiated). To get a better understanding of lights and shadows, have a look at https://doc.babylonjs.com/divingDeeper/lights .
