Cloud brightness dawn/dusk/night

Featured Replies

Hello.

 

Why are cluds white without any light? The clouds should be darker. I've tried to set the lightning in the display settings but i couldn't fix it.

Any idea?

 

Sorry for my english.

 

Kind regards

Yes. Clouds should be much darker during night (no full moon). I tried different HDR settings but this does not change cloud brightness. Some shader settings (HDSL?) have been discussed during v2. Don't know if this is still applicable with v3.1.

Continues to be an issue with the look and realism of night flying in P3D.

 

In v2, as others have mentioned, we went through lots of tweaking to get BLACK nights (when it should be of course)...

 

Super dark night flying, along with all the cockpit challenges of that, are really quite fun actually.

 

Would love a slider of some kind to handle this in settings..

I agree. The clouds are way too bright. So are the ground textures and everything else. Feels like i am flying at dawn for 8 hours.

The way I have worked around this is:

 

1. Fly at night with no cloud and no moon to give the darkest night.  But that would not solve your issue if you do want clouds.

2. I have a setting on my displays that I can switch to when flying at night.  The RGB is adjusted to give the darkest appearance possible.

 

Only suggestions... as you know we cannot achieve total darkness like in real life.

Netgear 1Gbps modem & router, (3) 27" 1440 wrap-around displays
Full array of Bravo, Saitek and GoFlight hardware for the cockpit. Varjo and HP VR headsets for mixed reality.

It is not about total darkness, OP was talking about white/bright clouds. IMO clouds should appear more dark-grey, bareley noticeable.

Yes, this is a bit annoying, if anyone figures out a solution, please share.

It was so annoying. You may try solution that i've done for myself by modifying shaders file.

 

modified file:


 

instructions how to set up:

1. Close P3D if already running

2. Pls make a backup (copy) of your default shaders file [Prepar3d directory]\ShadersHLSL\Cloud.fx

3. Copy modifed shaders file Cloud.fx_ver[X] (now it is in version 5 so file name is Cloud.fx_ver5) to [Prepar3d directory]\ShadersHLSL\. And rename it to Cloud.fx (with overwrite existing file)

4. Clear the shaders cache: Delete all files in directory [disk where Windows was set up]:\Users\[user name]\AppData\Local\Lockheed Martin\Prepar3D v3\Shaders\

5. Thats all. Just start Prepar3D.

 

If something goes wrong (artefacts, FPS decrease, or you dont like how clouds looks now) restore previous state by:

1. Close P3D if running

2. Copy previously reserved file Cloud.fx to [Prepar3d directory]\ShadersHLSL\Cloud.fx.

3. Clear the shaders cache: Delete all files in directory [disk where Windows was set up]:\Users\[user name]\AppData\Local\Lockheed Martin\Prepar3D v3\Shaders\

4. Restart PC.

 

What was modifyied in clouds in tweaked file:

- clouds color in dusk/dawn was enhanced to get more picturesque scene

- dusk/dawn overlight was eliminated

- night clouds luminance was tied to moon (volume, light volume etc.)

- cloud in daytime slightly "volumized"

 

And I recommend use REX Soft Clouds with this modified shader. it looks great in my opinion.

[sorry for my English]

Yuri

Interested in this issue as I have the same feeling about night flights.<br /><br />I have bookmarked this topic and will test this shader mod hopefullly tonight at home. Thanks :)

Just erased ALL clouds for me, sorry.  V3.2

Firstly, thank you for tweaking such files and for discovering the haze tweak which I believe is now being packaged into an installer by someone else.

 

I'd love to give this a go but I think REX 4 Texture Direct also modifies 'cloud.fx' to increase the size of clouds, thereby eliminating the 'popcorn' effect as far as possible. If only I knew what changes REX makes to this file, then I could essentially have your tweaked values as well as the larger clouds.

I'm going to follow this topic and keep a sharp eye on what becomes of it.

Daniel, sorry for this, but it was old version file for Prepar3D v3.1 only, so now I removed link to the file.

 

krazyk, yes, I hope great utility tool by Pe11e will be the most convenient way to make such adjustments

Yuri

Pe11e released a shader mod that helped with this and he's now about to release a new version with a GUI and sliders to fine tune the adjustments. Takes all the work out of tweaking numbers one at a time. Should be out by the weekend (as far as the last update says).

Thanks but link does not work - you delete the file ?
