I was thinking about adding even more details to the scene, and crepuscular or god rays would be an amazing addition, and since you have already implemented light absorption, wouldn’t it be possible to use that to make some low cost god rays?
I don’t fully understand how water and light interact with each other, but i assume that god rays are there because of the wavy water surface, making light penetrate unevenly?
I’ll try to find some papers on that subject and see if i can come up with something
