P3D V5.3 Missing Horizon/Atmo Haze

[Aussie1234]

Sorry 737 Sim guy,
I know it needs to be coded :-) but what I meant was, a few versions ago, I followed good advice here and modified some code in a couple of files. It worked, and fixed the particular problem. Then later a HF came out, and it replaced another file, and then, combined with the two other files I had modified, created entirely different problems for me. Took me a long time to fix as I had forgotten which files I had modified code in.

What I was saying was, It would be nice to have an official LM replacement file, to fix the missing horizon haze, without using an XML editor.

Yes of course, totally understand. I was just trying to be tongue n cheek silly :-)
If we can’t smile once n awhile through all this then what’s the point right? Hehehehe. It’s nice to see LM is still in the game…

After 20+ years I still use Lotus Notes for saving things like this.
Easy to forget stuff after so many changes, tweaks and mods over the years.
Gettin older doesn't help much either.

The hot fix is live now.

Thanks Beau!

Happy Holidays.

Hi,

I just installed the Hotfix Update 5.3.15.28131 (client + scenery) and ran 'Delete generated files'. But it looks like the haze problem isn't properly fixed yet: flying with clear sky, mountains at a distance keeps growing or shrinking like before...

I tried to solve that by re-using the fix to ShadersHLSL/FuncLibrary.fxh provided in this thread before the Hotfix was issued, but that doesn't work anymore in the Hotfix version...

hmmmm.....

should I do a full re-install instead? (it wasn't required according to this: https://www.prepar3d.com/news/announcem ... 12/120943/)

OK:

Now I completely removed P3D (also the folders in %appdata% and so on) and did a clean install of the Updated Hotfix.

The haze is back, so it works as expected now.

Hi,
I installed 5.3 HF1 update 1 and I see that, with EA on, even with CAVOK and unlimited visibility, there is a lot of haze, I would almost call it slight fog. Is there a way to reduce it? Thanks.

I tried the FuncLibrary.fxh fix in my P3D V5.3 HF2, and it didn't work, everything was black. I assume it was meant for HF1 and was rolled out in HF2, but I still have the issue of a slightly fixed haze. It's not as bad as the solid line, flickering terrain, but it still is relatively solid as other people were saying.

I had a black screen too after doing the fxh fix, and it turned out that using the select code leaves out the last line. After manually entering the last line "return float4(....." and the closing } it worked as expected.

Cool thanks

Does this fix only work with no addons installed such has active sky,Active sky cloud art? If so would I have too uninstall these addons and not install them after I’ve implemented the fix? Or it is possible too install the addons after I’ve implemented the fix?

Hello all,

We have a shader fix to bring back the horizon fade behavior while maintaining the improvements made to fog blending and curvature correction of layers below the camera. Since it's is a shader-only change, I will post instructions below for those that want to try it before we put out an official fix.

Note this instructions assume default P3D shaders, so if you are using an add-on that modified our shaders this may not work as exptected. Also note that you will need write permissions to your install directory which may require admin rights.

First locate ShadersHLSL\FuncLibrary.fxh and save a backup copy in case you into any issues.

Open ShadersHLSL\FuncLibrary.fxh in a text editor and look for this line of code:

Code: Select all

    return float4(fogInscatter, transmittance);

It should be around line 505 at the end of a function called CalculateFogAndTransmittance. Once you find it you can replace it with this:

Code: Select all

#if !defined(SHD_ENHANCED_ATMOSPHERICS_BLEND) && !defined(SHD_TO_FAR_CLIP)
    const float distanceFogTrans = min(transmittance, CalculateExponentialFogBlend(distanceSq, cb_View.mFogDensity));
    fogInscatter += cb_View.mFogColor.rgb * distanceFogTrans;
    transmittance = saturate(transmittance - distanceFogTrans);
#endif
    return float4(fogInscatter, transmittance);

Then clear your shader cache by removing this folder or deleting it's contents:
%LocalAppData%\Lockheed Martin\Prepar3D v5\Shaders

Has this been fixed in v5.4? I applied the fix and have this sun/atmosphere:


EA off.
