Night sky too extreme in VR

Anyone else using VR think that the night sky is extremely crowded with stars?? Looks like long exposure photo, even near large cities…

I have been around a few desolate places in my life and been taking night sky photography and have Never seen a night sky as bright and starry as the one we have in VR. Also the stars looks smudged and blurry. Flying on a clear night in VR is a mehh experience at best.

Hope it will get fixed in the future. Or even better. An adjustment option for individual preferences could be added, then there arent even anything to argue about.

It seems a little “starry” on the regular monitor too… especially around cities

There is already a topic about “Stars too close” which is related somehow. In effect, the stars seem to be just a projected texture. This explains their look and feel, and probably the “too close” factor if the dome they are projected onto is just too small. This also explains why star magnitude is not rendering correctly, because it is just a pre-painted texture with static stars. At the same time, your topic is different because it is not about “too close” but about “magnitude”, and for this, it would require the stars are not painted on a texture but painted as individual light dots.

For these reasons, I’ll copy my remarks from the other topic:

  • 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:

Wow… Thank you for this in depth post/reply.! I am however sure it is on a list in a drawer somewhere at Asobo… Pretty sure they can also see the issue and the night sky was down prioritized to meet their launch dates etc. For now I just fly in daytime.

I thought it was an HDR texture though. Changing the exposure setting on the camera brings fainter stars into view.
