When scrolling around the space platform view the background stars move at an implausible speed
as if they were closer to the platform than the planet itself. This applies to any planet as far as I know.

Attached are two videos, first shows the ingame version, second is an example 3D scene with similar composition.
Notice that as I am moving the view up in the game (the planet and stars are moving down) the stars which are above the planet are "moving closer" to the planet. Whereas in the 3D example as I move the view up the stars "move away".
A reasonable fix would be slowing the star panning speed to be slower than the planet.

Thanks for the report however this is not a bug.

The stars render behind the planet, so they are supposed to be further away than the planet. However the parallax speed suggests they are closer to the camera than the planet. This is disorienting and clearly incorrect, how is that not considered a bug?

Not a bug generally means that the game engine is doing what it was programmed to do, and there is not a Crash or otherwise Broken behaviour to be fixed. It does not mean that it is Realistic - this is a Video Game.

Good Luck!

This isn't really about realism, it seems like a mistake that slipped through which breaks the scene and can be easily fixed. It's the same sort of mistake as if the stars rendered over your space platform. If this is supposed to go in suggestions instead of bugs, that's entirely valid, but saying "not a bug" does not make it clear.

When moving around in a space platform view, the star parallax scrolls faster than the planet. This makes them seem closer than the planet which contradicts the fact they are rendered behind the planet. I am not complaining about realism, I am reporting a geometrical impossiblity implied by the scene that feels off even when you can't explain it.

The solution is simple: Change the default star parallax to move slower than the planet (change to a lower value like 0.1) or make the planet parallax move faster than the stars. Attached are videos of the current state and a possible fix.

This is seemingly a duplicate of this issue viewtopic.php?t=135066, however I believe the previous issue was flagged as not a bug due to a misunderstanding. If that's not the case I'd like an explanation why this is not considered an issue.

This is not a bug because we are not aiming for realism. Both features were designed independently and both work as desired currently.

It is not about taste or being scientifically accurate, just pick whether the stars are in front of the planet or behind it, not both.

I bet you guys have heard about integration testing and not just sole unit testing. It can do wonders for user experience besides business requirements.
