This brings PhysicalSkyMaterial's Night Sky functionality to ProceduralSkyMaterial, but in a more powerful and general fashion. This can be used to display stars at night, or clouds at day and night. For clouds, it won't be physically accurate, but it can look good still. The Sky Cover Modulate property can be used to adjust the sky cover's colors and opacity in real-time, which is useful for day/night or weather transitions.
