Atmosphere height on procedural planets cannot be changed, it is computed by SE. This height depends on mass and radius of a planet - less massive planets have more "wide" atmospheres due to lower gravity. If you compare atmospheres of massive terras with smaller ones, you will see the difference.

The only planets i've seen with that thin atmosphere are large ones. diameter 2+

I think the atmospheric pressure is out of wake though. A 0.3 Em terra should not typicality have an atmosphere 30 times thicker than earths which i have found many like this..... I have a better description here.

Well, I check my code and found a mistake. Atmospheres are really being generated with too high thickness, 300-400 km for earth-like planets. I reduced it (use another formula) and now planets looked more natural (like Earth and Pandora).

However, there now problem with clouds - sometimes they should be placed almost at the top of the atmosphere. Current engine don't allow clouds intersecting with mountains, overthise it leads to horrible artifacts while looking from space or high altitude. This is a reason why clouds in SE are so high, 10-20 km above the ground. But now, with reduced thickness of atmosphere, sometimes clouds are looked very strange, flying almost in black space. May be that was a reason why I made atmospheres so thick, I can't remember now.

I should refactor something the engine code in some way to make it support clouds intersecting with mountains and make cloud layer height more realistic.

Im glad you had it in mind Space Engineer. biggrin Could be a fix for the next version, But I don't impose.

I rather like the thin atmospheres better than the thick ones. I think thicker atmospheres make the planet look smaller than it actually is.

Yes, which is why this whole discussion has been about making the atmospheres thinner smile

if you've ever played spore, some really thick-aired terras remind me of the planets from the game.

Yeah, but that fit the atmosphere of the game (ha, puns).

And the planets were, in fact, small.
