If you want proper CB's modelled correctly...XP12 is the way to go. Clouds and the atmosphere is far more realistic than MS2024...and that from a IRL pilot and meteorologist. 

That's fairly subjective.  I've had great realism in both sims.  I think generally speaking XP12 can be slightly more realistic.  I'm a pilot, ATC (worked in towers for 15 years) and hold a NWS Certified Observer certificate.

My most realistic clouds I've seen in MSFS and XP12 (both live wx):

 

What would be nice is if it changed dynamically. I don't know if it's possible, but back in the days of REX on P3D I changed the sky color at dawn during the day as well as the sunset so as not to have the same one every time. On 2020 and 2024, we always have the same sunrise, always the same blue sky and always the same sunset... It would be nice if one day we had a pink sunset for example and the next day very orange...

Yes, I agree! The ability to change the sky colors at dusk and dawn is something I really miss.

I have to say that I'm so excited about sepia mask. It was the main problem that I've stopped simming at night. By looking at the images it looks so promising that's why it'll be day one purchase for me. To be honest, I've always been satisfied REX products, and I like supporting you as well. I just have one question, does this sepia mask removal applies the entire world ? IIRC in MSFS it was worked but it was mostly cleared in Europe but when you fly places like Dubai for instance it was still very much visible. So if REX can remove the sepia from those areas as well, that'd be crazy 🙂

Interesting...but I do wonder if it totally eliminates it because I think the sepia mask is a decent idea for the very distant areas so you can see the city 'glow'.  The problem now in the sim is they just have it too close....it needs to be pushed out 40-50 miles so you can see the distant cities (and not have fields glowing underneath of you!) but then that requires getting the current 'actual' lighting to extend further as well to fill the gap. I think 2020 has it pretty decent but they unfortunately messed it up in 2024 a bit. The sepia mask and night lighting improvements are supposed to be in SU4.....of course that could be a ways off!  Not sure if simply eliminating the mask at this point solves the full problem but interested to see/hear more about it.

The ground definitely does not glow IRL like it does in the sim. The whole night environment needs a rework. I’d also suggest they do something to get the orb look of lights out as street lamps are covered on top. 
 

Till this day don’t think any flight sim has nailed the night environment and flying experience.

Oh I agree....but I think if they used it out near the horizon it is acceptable since you would not see individual lights out that far.  But yes...the entire night lighting system needs to be reworked!  I swear they had the night lighting really dialed in at some point in 2020 with a mix of colors and more of the light reflection on the ground instead of the FSX style orbs we are back to now....

If this product can add haze to the atmosphere, then I'd likely purchase it. 

Can not believe MS2020 and 24 still can not simulate haze. It's outrageous!

I remember one of the developer streams at least a couple years ago where Jorg mentioned they were planning to revamp the night lighting using separate night maps or something to that effect.  I guess he forgot.

He did not forget. It's planned for SU4 later this year.

NOO...  All I wanted was for the sepia mask to be removed.  Someone has finally done it, but it's in 2024 not 2020!

Would be a day one purchase for me if they could rid 2020 of it too.

Others have stated this as well. Yet the other day, with real world weather, I had a beautifully rendered haze, even an inversion layer!

With Rex Atmos for MSFS2020 it is easy to add some haze to live weather. Just add a tiny fraction of "fog" and you get a much more realistic visibility range. It is also possible to increase humidity which "thickens" the atmosphere and reduces the visibility range. Looking a lot better with these tweaks I think.

In addition you can "whiten" the clouds so they are not so gray and dark. This also increases daylight on the ground, which in my view is far too dark in MSFS2020. For me this program is a must with MSFS2020.

Yeah, I regularly see excellent haze in live weather. I just think it’s only metar based (?) so you get pockets of it.

Both changes nice to have the control over. It is frustrating that live weather doesn’t have more of the visual control the presets have, which can look very convincing. Is Meteoblue’s data just not being parsed very well?
