Unity 2022.3
Altos is the complete sky system asset. Set the stage with a highly configurable procedural skybox. Place suns, moons, and planets with controllable orbits. Create your universe with multiple layers of stars that can rotate in sync with your time of day. Add physically-based volumetric clouds that you can fly through and above. Build even more detail into your sky with physically-based high-altitude cloud layers.
Give players a living world with dynamic temperature, wind, and precipitation. Use these environment states to drive weather events. Electrocute your player with controllable lightning. Light your world realistically using a lightweight real-time sky-based global illumination.
