Not RVR but yes for general visibility through two slides (fog and humidity) with a variable value from 0 to 100.

I am not allowed to post images, I'm sorry.

Perhaps I'm missing something, looking at the YouTube videos, but I don't see any place where you can set a visibility value, for example, 2 NM. I see the two sliders you are talking about, except for what I'm looking for specifically. Different features.

But does it always make 10SM of visibility?  In the US 10 is the highest visibility reported on the ASOS even if the true visibility is 50 miles.  

Sorry. not sure what that means. Are you saying no matter what you never see pass 10 miles of visibility

With regards to rex.  In the past some weather programs would only generate the amount of visibility listed on the metar.  But 10SM is just the max amount in USA metar strings.  It doesn't usually literally mean 10 miles.  It could be 50 or more miles.

That is standard worldwide, not just the US.

... Just the unit changes and so the threshold. For example, METARs report greater than 10 kilometers (~6 statute miles) in France.

For everyone who also uses Reshade too :

 

Especially see the last part of the vid where hé shows how to control the Bloom at night.

Looks good what he shows in the videos. But for me, he misses still proof of one important claim: set and forget also in relation to different weather presets/live weather. His videos do not contain proof for this claim, he only shows Boston and the same weather, at least with variying times of the day.

My experience is that if you want to use presets 24/7 just make small adjustments.

If you want it spot on for a certain place at a certain day and with specific weather then you might end up with more adjustments, but it might look not entirely good 1000 mls away half a year later.

Like a mentioned before : the AB presets are a good way to start.

Tip : If you want less Sephia effect at night just set the Particles Scattering RGB look higher.( Use the Lock )

But not too much as your horizon gets less sharp. Not an issue at night, only at daytime. I have it slightly higher so a softer horizonline and also less Sephia effect in the distance.

Thanks for the advice!
Because I'm hesitant to buy it too, and having to pore over a bunch of different sliders, always trying to tweak it endlessly, isn't what I'm looking for!

And likewise, you only need one preset to use it at any time of day without having to change the setting mid-flight, because I went from day to dusk, then from dusk to night...

But I understand that in the future, Atmos should have dynamic settings?

That, on the other hand, would be great!

If it could dynamically modify the Atmos settings in real time based on the weather and the time of day, that would really be a step forward!

I've always wanted to have different sunsets/sunrises depending on the weather.

Are they planning to do that in the near future ?

 

EDIT:

seen on their site: 

Future-Ready Features

Upcoming support for dynamic changes and integration with REX Weather CORE.

Does anyone know what sliders have to be tweaked to get a slighty darker blue sky when flying at very high altitudes?

I would want this too!

For example if I'm flying GA on a 100 nm flight, and my start is foggy and low vis, but my destination is clear and VFR, then I'd expect Atmos to give me the low vis at departure, but my arrival should have a lot more vis.    It sounds like at present time, Atmos would require you to MANUALLY change the visibility yourself at some point during the flight (??)

I'd love to be wrong about that though.

To answer your question, I just started using Atmos in MS 2020.  I have loaded the AB presets for all three functions, and didn't adjust any of them. For weather I use Live weather from Active Sky.  I just completed a flight from EICK to EGGD.  The weather at the departure was heavy rain, and lightning, and maybe 1000 ft RVR.  I took off and as I climbed out to FL200, the weather started to clear up, and got sunny for awhile. As I approached EGGD, I flew through some showers and the weather at EGGD for the arrival was a  few clouds. So yes, it seems to recreate the weather, or the way it looks, following the live weather from the sim. I didn't have to touch anything in Atmos. 

I don't really understand this program.

I already have weather changing during flight in msfs2024. How is this any different.
