| Quote (brainstorm) Saturn model in dynamics - as in case with Jupiter - 10 layers (cloud belts) with different (real) speed and direction
Very nice! Wow...
Will you make Uranus model? It has very contrasting colors, such an effect would completely change it!
The universe is not required to be in perfect harmony with human ambition.

| Great job brainstorm with those clouds layers, it's a very nice illusion ! Thanks for it!

| Sorry, did I miss something?
Is Brainstorm SE under a different screen-name?
Only 1 post ever? And it's epic!?
What's going on?! This is wrinkling my brain!!!
And, on the subject of these awesome cloud animations:
Are they at slightly differing altitudes? Could they be?
If so, (long shot) would the ring-shadow-casting thing work with them? It'd be great to get into very low orbit and have the sense of depth enhanced by seeing the shadows of one cloud belt overhanging another.

He has more posts on the Russian forum

Of course, that's the only way it can work.

Of course, they're just normal cloud layers

EDIT: To answer your question directly: currently, no they don't.
It would be cool to see cloud shadows in the future, though.

Indeed it would! I really miss it while watching the Earth from close range. 
Love Space Engine!

| I had never thought about it until now. It'd add a nice, "cheap" bit of dynamism to the landscapes of SE.
Something like that doesn't have to be too computationally expensive, right?
It doesn't have to be ray-traced, or dynamically shadow-mapped, it can be approximated with just a projection of the cloud texture onto the surface texture as a subtractive layer, or something. That's probably how Celestia did it, right?
Knowing Space Engineer, it's definitely already on the list.

| I'm envisioning a similar method to how the ring shadows work.

| Huh, I never noticed that SE didn't have cloud shadows. Weird, even Celestia has them.
Quote (anonymousgamer) To answer your question directly: currently, no they don't.
It threw me off because he asked about ring shadows, not cloud shadows, but then changed direction and described cloud shadows and not ring shadows. So I just answered the question that he asked most clearly.

It sounds easy, but in reality it is not easy. Each planet in SE have a lot of textures (200-300 at ground level), mapped on a square-shaped tiles of landscape. Clouds layers uses the same technique. So it is impossible to make "just a projection" - each cloud tile may project on many landscape tiles, and each landscape tile may recieve shadow from many cloud tiles. So easiest way is to implement usual shadow mapping.

| Oh! Wow... does that mean that you intend to do it?
Or would it be too tempting to 'kill two birds with one stone', and implement landscape shadowing - and possibly drive up the computational load too much?

Yes, my wording was a little ambiguous, sorry about that. I was actually asking if the technique used currently to cast ring shadows would work with the different cloud-belt textures.
Thinking about it further (and with a clearer head), I imagine that the ring shadows are not mapped at all, but rather take their cue from the density variations in the ring algorithm's output for the planet in question - drawing bands of darkness along the appropriate path on cloud, atmosphere, and landscape models.

Its been mentioned that whatever exists in real astronomy will be implemented so I assume that stuff would be added eventually. I doubt it would be too heavy on resources if 64 bit support is eventually added, plenty of modern games do far more things at once.
