@nprofile1q... I haven't played it, but they have a really nice volumetric cloud rendering system. I'm guessing they're using stacks of ground-parallel alpha masked layers to make them so nice and round, and might be doing ray marching to figure out the light propagation. Much fancier than what I've got, though I have the math worked out such that I can generate the geometry needed to do layers like that. Those are aspirationally good clouds.
