General Rekindle work on planetary weather?

I mean... walking is kinda cool and all but it's also underwhelming after 5 minutes of the same old muddy geometry every planet. Why not spice it up with some procedural dust storms based on planet characteristics?

The weathers could be determined by a simple random seed generated at server start. This will make weather consistent across all users.
And to simplify things for a nice beta version, you could just generate a panning noise map (using the random seed) biased by the star-facing vector that determines the storm's position for each planet updated every half-second (to save performance). The "Wind" direction would be determined by the noise panning vector. The only time anyone would notice that it's not perfect is when they stand at the very edge where the value clamps are. You could further improve it later with the help of a meteorologist to figure out how a storm would really form... if you really want to.

The intensity of each planet's weather could easily be biased lower or higher depending on the thickness of the atmosphere, the speed of its axis rotation, and its distance from the parent star (or eccentricity of its orbit) storms on binary planets could be a dangerous sight to behold, with the most intense storms forming at a terminator ring facing the nearest orbital body (Creating an "eye of the storm" effect).

Will there be clouds to represent where the weather is? You could just feed a cloud shader into one of the invisible spheres that encompass each planet and plug in the weather noise texture to determine their locations.

Obviously since the only data required from the server for the desktop clients to run this system is the generated seeds and the planet characteristics (which we're receiving anyway), there should be no server performance hit.

I'm sure you guys know what you're doing and are perfectly capable of making a better system than what I just described, but even this would make a lot of people happy without making anyone else particularly upset.
 
The atmospheric pressure on the current planets doesn't support water vapour clouds, I expect there will be clouds when they release planets with higher atmospheric pressure. Most planets with clouds that aren't water vapour have a far greater atmospheric pressure than the current released set of planets so it's just a matter of waiting.

Who said anything about water vapor?

Having made weather systems in Unreal Engine myself, a puff of dust or smoke is the same as a cloud in videogames, shader-wise and behaviorally.
A cloud of dust is an accumulation of particulates suspended in air or otherwise held together through various physical properties, they do not need to bond to water particulates.
There are severe dust storms on Mars, which only supports 0.06 atmospheres.

You said clouds, which implies suspended particulate matter and not blown into the sky by the wind, you already get dust storms;

To be fair, I've never seen this before, and I've landed on quite a few planets.
That means it's rare enough that I didn't think it was even in the game.

Also a "Cloud" is what I'm looking at right now, it's just at ground level.
Basically a cloud is just a bundle of particles that obscure vision. Whether it be water vapor or dust doesn't matter.

Side note: If you drop into either of the Lagrange clouds in Oort and a few other places in Odyssey, you'll see that their cloud tech is starting to look more and more dare I say atmospheric. It's likely a whole other level of complexity to apply this all over a body's surface, mind you, but the in your face part seems to be fairly good now.

Quite honestly, I always thought that the LaGrange clouds were going to be their testing ground for what we would see in a gas giant environment. This is why I always been under the impression that gas giants we're going to be the first kind of planets we could dive into. Imagine my surprise when it was only .01 atmosphere as a pressure that we would be dealing with for this last year or so. Well I'm hoping for gas giants eventually and maybe space whales floating around in them.
