Yes, we got that raymarching cloned glitchy-looking rocks inside the rings but was necessary to remove this interesting windy-dusty texture?

Apparently. But they also stressed several times that the work for new rings is not completed at all.

Aha. Many things are. Developer doesn't even visit the forum anymore, he appears once in several months now.

I think the distance from the rings where you would see the noisy texture in previous versions is now about the same distance where you start seeing ring particles in build 1865.

No no no, this is not how it works. I remember that old blogpost where this windy texture was introduced and it said this corresponds to reality. In reality, when approaching the rings, we will first see this texture, and later - the particles themselves. Here is a real astrophoto on which the texture is visible, but the particles are still far away.

Yes, the texture is realistic, at least for some parts of the rings:

Ring systems -- especially Saturn's -- are complicated. The texture is not the same everywhere, as it depends on things like particle size, density, and perturbations from moons. I'd like to see the texture brought back in the future, too, but better showing those variations. There are also many other complexities of ring systems in nature that are important. Adding the particles and the effects of light scattering through the rings were big steps in the right direction.

I wonder, we only know about rings around gas giants, and there are so many fine rings, i.e. dust with very uniform orbits.  But gas giants are themselves uniform with uniform surface gravity and a simple geoid.  What about rings around rocky planets with a complex geoid?  Would the rings be quite different with more large scale texture?

If it was complex geoid then rings wouldn't exist long. They need gravity to be stable, otherwise they will just fall.

Well, that also would count as "quite different".  But it might not be completely binary, not either smooth rings or none.

I didn't understand what you say, but Luna is a complex geoid and thus it has gravity anomalies. Because of that no satellite can hold on its orbit for long. Same would happen to rings. We are not even talking about thousands of years. They would fall off very quick, like several years.
If you want some different rings - Uranus and Neptune have them.

What I'm saying is that there must be planets between gas giants and planets that wont have stable rings, and what would rings around those look like?

Good news is that Earth will be getting its own set of rings in the future, but they will be made of space junk :)  Isn't that perfectly symbolic of humanity lol? I wonder if space junk rings can ever be as spectacular as what Saturn naturally has?
Also, as far as you know, are Saturn's rings unique or do we have an exoplanetary example of something even more complex and spectacular?

I wonder about this too, there are actually rings around some rocky planets in SE....I believe Tau Ceti has a spectacular planet like that.  We need to separate the kind of rings Saturn has vs what the other gas giants have, because Saturn belongs in a class by itself.  Still, I wonder if there is an exoplanet somewhere that has even more spectacular rings.....I remember reading about this awhile back but don't remember what planet it was.

There are planets between gas and rocky but you can't have smth in between having or not having rings. They either exist or not.

You need a supercivilization to do this. But supercivilization can clean its own mess.

"do we have an exoplanetary example of something even more complex and spectacular?"
Planet J1407b has HUGE rings. But some say this is more like proto disk of a red dwarf.

"We need to separate the kind of rings Saturn has vs what the other gas giants have"
Do we?

"because Saturn belongs in a class by itself"
Does it?
