Thanks a lot MrBitsFlyer and Maya2 for the clarifications 🙂

The single and multi rat are constants of the atmosphere and they never change based on conditions.

The turbidity is set by the weather engine, as it controls the haze amount. Overriding turbidity will indeed prevent variations of haze brought by real weather.

That is a shame, I thought it just changed what real weather was inserting during updates.

At least the script can be easily turned off for those days of true low visibility

The turbidity control is for the aerosol turbidity, which is only used for depicting visibilities down to 8 km. So lower visibilities (< 8 km) will still be correctly depicted as such visibilities are depicted not using aerosols but using a water "cloud" (fog) layer rather instead.

After testing "single_rat" at 0.5 (the other two drefs were unchanged) on a flight with real weather I'm back at the default of 1.0. More aerosol just obscures the ugly horizon transition between orthos and the low rest planet model better when one is at cruise altitude...

I noticed this today flying out of KDSM.  Low cloud and rain with low visibility.  When I was far enough west the visibility returned to my pre-set.

That sounds good, so what settings did you settle on?

Very odd - the Haze script is now opening with a blank window, even after re-install.

New version of HazeAdjust available.

An update on the settings I am using.  The 'single' setting makes a huge difference when lowered right down from the default 100.  It affects the amount of haze produced when looking towards the sun.  A 'single' setting of 100 blots out the sky with haze, but tuning around the 20 will give great results.  I leave 'multi' at the default value of 125. Reducing this just over saturates the colours around sunrise and sunset.

By reducing 'single' as I describe, you get a much better sky to adjust 'turbidity'.  I find 160 to give a realistic sky with the horizon/sky merging together nicely.

The lighting/haze/ and colours with the settings above on my PC.

lol.  I had to chuckle at how fantastic that looks.  I don't care what anyone says from the other side.  Those clouds and lighting can't be touched by any other sim.  

(Can't believe I have to say it, but, for the sensitive ones who want to argue, DISCLAIMER.  This is my own opinion.  If anyone disagrees, you have every right to.  I also have the right to not care.)

Since the update of Xplane 12 clouds and lighting... I've not touched the competition and never will again. The Xplane 12 atmosphere is incredibly realistic... especially adding Visual XP to the mix where you can adjust the appearance and density of the clouds. 

I've spotted all sorts of cloud types realistically depicted that I've never seen in the other sim....and as a satellite meteorologist, I am very satisfied with what the weather engine emulates. I'm very hard to satisfy in this regard.

Flying through frontal cloud layers is my favourite activity... it's so word not allowed realistic...including fallstreaks!

I know, almost unbelievable what Laminar has achieved with the clouds and lighting.

Is that product still relevant after the cloud and atmosphere changes in 12.2?

Just did a flight in 2024 which I have not done in over month and I fully agree.  It's just the same old sky colors, unlimited visibility and puffy cumulus clouds everywhere (even above FL 300) using Live WX so the overall flight was a disappointment...oh and I also had a DXGI_error CTD at around the 90 minute mark....

I personnally haven’t used it since over half a year. And I don’t think it is really needed. But perhaps is is worth giving it a try if you already purchased it. Otherwise I don’t think (added to that, knowing that the dev has disappeared and doesn’t update it anymore).
