General Question Earth sunset atmospheric effect

[xionx]

Orbiter has the capabilities of showing the Rayleigh scattering effect, for example on venus we can clearly see it (see the screenshot below) :


However on earth, why don't we have any limb glow visible from space? If orbiter has the capabilities why it hasn't been made for Earth?

(no limb glow :'( )

Would it be possible to achieve this with a mod?

Thanks in advance !

This isn't really helpful....
See my screenshot, how did you do that, I don't have it

I'm guessing you changed these settings, could you share your preset?

But I'm only guessing, because even the sun seems different in a better way....
Would love to know how you did that lol

Which version of Orbiter are you using.

This is just default O2024:



There are a few other options for "Earth Visual Config" under D3D9 client settings > advanced




2024 has a pretty significant visual improvement over 2016, but 2016 still looks great.

Actually implementing this sort of thing, and having it look good in all situations is really hard. The actual physical phenomenon of sunrise/sunset colors involves brightness values that span ~5-8 orders of magnitude, and that has to get condensed down to 8-bit color and 2 orders of magnitude of brightness, and be performant.

I disrespected Orbiter 2024 to have too few minor ajustement to be called like a new version of Orbiter.
I did stay on Orbiter 2016 for stability reason, I got a lot of bugs using addons on the "new" version.
But fair, also I don't even think I have the lastest orbiter D3D9 client somehow...

I disrespected Orbiter 2024 ...

I have both Orbiter 2016 and 2024 installed. But more and more I use the 2016 only for quality control = testing new addons with the old version.
Actually I am quite happy the community made a new Open Orbiter! The visuals are great, old addons either run directly, or with minor adjustments.
I think, most improvements are 'under the hood', not openly seen, but a step forward to a modern simulation.

If you are using specific addons in 2016, which do not run under 2024, maybe you could contact the addon developers to upgrade them. The community is very friendly and open to suggestions. You could actually become part of the development process by testing new versions and providing feedback to the developers.

This is what I have with my own custom Earth atmosphere configuration file:
