I just getting started dabbling with game development and Unity. I'm creating a flying game, and so far have a player-controlled character set up. Next I'm working on clouds. I've set up Unity's HDRP and added their Volumetric Clouds. They look very nice at a distance, but something strange happens when I get close. I'm not quite sure how to describe it, other than the edges and other thin bits get sort of fuzzy, or pixel-y, or particle-y. I've attached an animated clip to show you what I mean.
(That's not distortion from the gif compression, that's how it actually looks.)
Sometimes, these pixel-y areas of the clouds seem to interact with the lighting to produce these unnatural (though admittedly very nice looking) streaks:
I'm not even sure what to call these phenomena, let alone how to fix them. Any advice on what settings to tweak or where to look for help is appreciated.
