Yes,I know how hard this is without making everything lag like my brain whe trying to understand modern art. But, a lot of indie developers like Hello Games,or Outerra project,or indie programmers,with DirectX 11 got this:

And,even this:

And, I know the effort and time that Vlad put on these, but, planets are kinda of the main thing on Space Engine,y'know? I have the ideia of how many objects there are and whatever but,the planets are very important part of the game,you spend days exploring one!

So,my original complain is the simple fact that the engine don't renderer those things. And,if Vlad contracted professional guys to do the work,it would be much faster. Opening a kickstarter is more efficient than,for example,waiting here on the site,since SE is little known. In fact,In the main state of the game,people would show a lot of interest. But Vlasd sayed something abou not being viable in one of the emails.

There are many factors to keep in mind:
- The codebase is very complex, and it may not be as easy to implement 3D volumetric clouds & water as it is in projects specifically designed to do so.
- Space Engineer has expressed a desire to remain as scientifically accurate as possible. Clouds & liquid bodies outside of Earth cannot be expected to behave as they do here. For example, Titan contains lakes, rivers, & rainclouds comprised of liquid ethane & methane. The dynamics of those liquids are vastly different than anything naturally occurring on Earth. Beyond that consideration, Space Engineer might also want to model a variety of other complex variables (wind conditions, evaporation, atmospheric pressure, tidal forces, etc. etc.)
- One of the videos you link to is a student's thesis project. Space Engineer doesn't have months free to implement dynamic water & clouds. He has limited time after work to devote to Space Engine.

If I were a billionaire, there'd be dozens of little passion projects I'd do. But one of them would be flying to St. Petersburg with an obscenely large amount of cash to convince Mr. Romanyuk to put together a top-tier team of developers & astrophysicists. After 5 years, he'd be awarded a Nobel Prize or two.

A Kickstarter campaign has many positives & negatives, but I doubt that Kickstarter would help Space Engineer accomplish his vision. He isn't bound to any sort of release schedule, and is able to take as much time & care on features as he feels is needed.

Q - Where is Kickstarter available?
A - Anyone, anywhere can pledge to a project with a major credit or debit card. Anyone in Austria, Australia, Belgium, Canada, Switzerland, Germany, Denmark, Spain, France, the UK, Ireland, Italy, Luxembourg, the Netherlands, Norway, New Zealand, Sweden, or the US can start a project.

Mosfet,yes,I know the doantion page,I even mentioned her in the commentary.
