Do you happen to know what hours/times of day "morning" and "evening" the postprocessor code correspond to?

It does not depend on time directly.

In post-processing code for DayNightUse parameter I use internal shader variable cb_mDayNightInterpolant. It used often in sim shaders code to determine lighting.

cb_mDayNightInterpolant not tied to time hours as I understand it. Only to sun altitude that may differs for the same time  depending on latitude.

Thanks! I think I prefer to use the code method (and DayNightUse:0) then the effect is gradual throughout the day . However - if I use the DayNightUse:3 (no code) method - then does the sim also use the sun elevation but simply not apply the post-process effect outside the times defined by DayNightUse? In other words - there may be a big jump between "twilight" and "day" (applied/not applied).
 

Does the sim also use these [same] sim elevation values to assign the corresponding palette and textures from things like REX/FEX?

Yep, in this case post-effect just apply or not.

I don't know. I suppose these caclulatons in core sim code, not shaders.

I have REX installed, and had no issues at all installing or using PTA, no error messages, and the changes all work.

 

I love that I have such pretty water now, I hate the P3D water, way to dark.

 

So far this has been my fave change.

Does anyone have any news about compatibility of PTA with the new P3Dv3.4.14?.

Cheers, Ed

I've made some tests, the current version works fine with 3.4.14.

 

Thanks again.

Do we first go back to the default shaders , upgrade to the latest P3D and then re-apply our PTA profile ?

Not necessary, shaders in 3.4.9 and 3.4.14 are the same.

I want to test PTA. Never used it.

 

I have a few questions.

 

I need RSP or URP? Only PTA? A good theme for start? I fly in Europe with HDR on.

Will i need to touch any setup in sim?

 

Thanks

Hi José

PTA provides the ability to make some adjustments in shaders. You can use it alone. No touching of sim setup requred.

URP provides the ready solution based on PTA tweaks (and demands PTA) and contains sky colors, tweaks and the other goodies. Thats why it's a good idea to use ready solution as a start point.

Anyway using PTA you can make additional tuning of ready solution in accordance with the personal preference later.

For sky i use ASCA with AS16.

Hello folks!
 
PTA 2.0 (beta) uploaded to site.

I'd appreciate any feedback you can provide regarding the beta version of tool. Send it please to trifonov.geo@gmail.com.

How to install PTA 2.0:

1. The format of ini files used to store presets was changed in PTA 2.0. All presets from the previous version of tool are NOT compatible with version 2.0. Please reconfigure the required presets in the new utility in accordance with release notes and your PTA 1.X version presets.
2. It's highly recommended to install PTA 2.0 in a new directory separate from previous version of the tool.
3. Before installation please make sure that you have the original (no tweaked) shaders in Prepar3D. If you are already using PTA 1.X you can restore original shaders by menu command "Actions - Restore original P3D shaders".
4. When original shaders restored, unzip distribution archive in separate directory. At first start PTA 2.0 should automatically detect target P3D version, find proper P3D installation directory, shaders cache directory, and create backup of used in tweaks shaders to \SHADERS_BACKUP subdirectory in main PTA directory. Config files, used by tool, will backup to \CONFIG_BACKUP.

Release notes:

1. New tweak "Clouds light scattering".
2. New tweak "Aircraft lighting". Old tweak "Aircraft brightness tuning" now is a part of new tweak.
3. New tweak "Autogen lighting". Old tweak "Adjust autogen ambient sunight" now is a part of new tweak.
4. Lighting tweaks for terrain was grouped into a new tweak "Terrain lighting". If you did not use all these tweak, just leave unused parameters with a default values.
5. New tweak "Autogen emissive lighting".
6. New tweak "Terrain saturation."
7. Old tweaks for luminosity of urban areas at night grouped into a new tweak "Urban areas lighting at night". If you did not use all these tweak, just leave unused parameters with a default values.
8. Rayleigh scattering effect now has the new option "Exclude clouds". When checked, effect will not apply to clouds.
9. New tweak "Sky fog tuning".
10. New tweak "Sky saturation".
11. New tweak "Specular lighting".
12. Reflection, refraction and granularity water tweaks was grouped into a single tweak "Water surface tuning". If you did not use all these tweak, just leave unused parameter with a default value.
13. Like in post-processing effects, all parameters of the shader's tweaks can use now not only simple values but various expressions with shader's variables. (Please see documentation for detail info.)
14. You can restore default (initial) parameters values for a single tweak.
15. In addition to the PTA built-in tweaks you can also use create your own tweaks. Use this feature if you have some manual corrections that need to be applied to the shader files. These edits will be applied immediately after built-in tweaks in order specified in the list. IMPORTANT! There is no error detection provided! To locate the errors in your code please activate an option "Content Error Logging" in General section of P3D settings. (Error message appears at sim exit).
16. The logic of preset saving was changed. The option "Autosave preset on exit" removed from the tool. Now you will be asked only if preset was modified.
17. New option that allows to receive a notification when the new version of tool released. (Update is checked once in 3 days).
18. User interface redesigned. Sliders removed but you can use mouse wheel (or Ctrl+mouse wheel) to change values. Some improvements and new skins.

Kind regards,
