I would like Babylon Engine to have a photorealistic sky, with procedural animated volumetric clouds, time of day with moving sun / moon, night with procedural realistic stars, nightfall and sunset with realistic lightning... ..and why not add a realistic water reflection! Something that is even better than what's found on today's AAA games. BabylonJS deserves it After lots of research, I found this amazing ShaderToy which meets all above requirements: https://www.shadertoy.com/view/ltl
