Stars too close?

I was flying at night in VR (Reverb G2) for the first time. I believe the stars are not located in the 3D space as they should be at the infinity, but much closer, like 10NM. I perceive their location much closer than the hills surrounding the airport (LOWS).
Moreover the stars should be a point light sources (just a single pixel) while they are a kind of rectangular blobs in the sim, way too big.

Probably a reason for it, like antialiasing, resampling, VR downscaling etc, but you are right, stars should be single sharp pixels.

or earth is flat and stars are just projected against the dome… :joy:

Filed this bug a while back, but no response. The ‘squareness’ is likely just due to downscaling though.

Yes, very annoying, in special because its soo good implemented in 2D.

Please fix this!

I vote for this topic too!

I don’t believe they are, on the contrary and here is why:

  • FS2020 is using a texture projected on a dome.
    .
    It is clear you can’t have enough pixels in the projected texture otherwise it will be massive a texture size. This approach to night stars is typical to games.

  • Because it is a texture it doesn’t take in account magnitude either.
    .
    In a simulator like X-Plane stars are point lights and the magnitude is simulated as well, so that you only see what you’d see IRL depending on the ambient luminosity too… To each his own.


For those wondering, and Asobo, the XP11 file with the data is plain text:
X-Plane11\Resources\default data\earth_astro.data

It has about 25000 stars in the form:
Ascension Declination Magnitude [name]

The file starts like this:

You can even edit this file in any text editor and add your own geometric figures… I never thought about this one until now :joy:

Is this issue already adressed?

I had a flight in VR this evening, and was surprised to see the stars in front of the clouds. And looking crazily close. Very distracting, and clumsy looking.
