In the Readme file of FU3 folder, there are references to clouds :

- Large cloud models (aka cumulus clouds).  

- "puffs" within a cumuliform cloud

- Large cloud decks are rendered using "puffs", arranged in a grid, and have a
"backdrop" when viewed from above or below.

Has anyone been able to correctly identify which is which in the sim skies?
 

 

If you're still interested, after a lot of testing, these are my settings for clouds. I removed everything related, and left just this:

;-------------------------------------------------------------------------
;CLOUDS
;-------------------------------------------------------------------------

;UsePuffCloudModels

;--In hardware, smaller values make the clouds puff-out when further away, and
;--will adversely affect framerate (defaults min=150, max=200).
model_puff_min 150
model_puff_max 200
;--This will change the size of the "puffs" within a cumuliform cloud (default=2)
model_puffscale 3
;--One factor in determining "puff" size (default=0.05).
CloudDeck_PuffOnlyRadiusRatio 0.050000
;--Maximum size of "grid" element (in whole numbers, default=16).
CloudDeck_PuffOnlyMaxQuadSize 32
;--Maximum size of puff, in whole numbers (default=5).
CloudDeck_PuffOnlyMaxPuffSize 8

This is my setting for sky:

sky_LowLevel1ScatterRedHW 1
sky_LowLevel1ScatterGreenHW 1
sky_LowLevel1ScatterBlueHW 1
sky_LowLevel1ScatterRedScatterHW 0.23
sky_LowLevel1ScatterGreenScatterHW 0.33
sky_LowLevel1ScatterBlueScatterHW 0.42
sky_LowLevel1OpticalDepthHW 800

Profile Sunset is buggy, it's at night. I selected Fair Weather-Cloudy, put hour 19:15, and saved as Sunset.

I tweaked again ReShade:

Techniques=LumaSharpen,Pirate_LumaSharpen,Unsharp,prod80_02_Bloom,prod80_03_FilmicTonemap,ContrastAdaptiveSharpen,Vibrance

Ah, thank you, Patrikmore. I will compare it with what I have.

I am virtually certain that there were supposed to be a greater number of cloud types in FU3 (based on one or two of the screenshots that are shown during the installation process), but that these were not implemented in time before Electronic Arts decided to kick the product onto store shelves before it was completely ready. Other evidence of this early release included the rather sloppy appearance of many of the taxiway centre and edge lines at various airports and airfields.

There is a kind of cumulus, but finally I decided to remove it:

UsePuffCloudModels

Because its integration is a bit ridiculous. Colour and size aren't ok to coexist with the others kinds of clouds.

https://1drv.ms/u/s!Aigh3EjyJKT3j-0rM7csjqzUN4lhkg?e=uewpdx

Frankly, I do not know what UsePuffCloudModels does???!!!

I activated it again.

And also I put:

;--Maximum size of puff, in whole numbers (default=5).
CloudDeck_PuffOnlyMaxPuffSize 9

It seems more natural...

Dear FU3 friends,

belonging the FU3 config file flt3.cfg and "cloud modelling" (but not only to that!) our old beloved friend Jon Point is in my opinion the master of it - well organized and good commented.
I have an big old cfg-file from him on my HDD and would like to share it here with you (I hope he is confirm with that). There are really much of use- and helpful comment lines in the cfg file which is for sure helping a lot of useres who are interesstet in tweaking there around their FU3.

But be warned - the file is really long. So may be you need some "page down" buttons repeating until you come to the interesting cloud section. 😀

Here it is and you can direct store it as flt3.cfg to see how it is working for you (except you need / use special joystic settings etc.)

Nice greetings

Ansgar:

Thank you, Ansgar.

I will dig into it, as I love tweaking my skies hehe... I wonder what the differences are between this and Laurie's.

Patrikmore, the UsePuffCloudModels is much better on. Without it, the big cumulus clouds have an unrealistic flat bottom

Found in a polish web page: http://www.adamsb.hg.pl/FU/FU3/zmiany.htm

Cumulonimbus with 'UsePuffCloudModels' disabled

Cumulonimbus changes significantly after using 'UsePuffCloudModels'

 

Edited November 25, 20205 yr by patrikmore

I took the whole bunch of Jon Point for clouds, and noticed an improvement!

In front of the clouds block, these two lines: haze_lowlevelhazelevel 0.1       UsePuffCloudModels

CloudDeck_PuffOnlyMaxPuffSize 9 (instead of 8 )

My settings for sky almost the same I had:

sky_LowLevel1ScatterRedHW 1
sky_LowLevel1ScatterGreenHW 0.995
sky_LowLevel1ScatterBlueHW 0.97
sky_LowLevel1ScatterRedScatterHW 0.23
sky_LowLevel1ScatterGreenScatterHW 0.32
sky_LowLevel1ScatterBlueScatterHW 0.42
sky_LowLevel1OpticalDepthHW 800

Two critical settings related with light: opt_gamma_correction 35         haze_scale 29

In DGVoodoo2 I have now for AA setting: 8x

My settings in ReShade:

Techniques=LumaSharpen,Pirate_LumaSharpen,Unsharp,prod80_03_FilmicTonemap,Vibrance,Pirate_Bloom,ContrastAdaptiveSharpen

It's nearly perfect, I would say.

For rain, snow, etc.. modelling, Jon Point config is a jewel.

It sounds like the never ending story, this affair of trimming the settings by myself.

I assure you, I'm coming to the end. I expect I do not bother many people with settings been changed, as I'm almost alone in the world playing Flight Unlimited 3! My last changes in settings are just these ones:

In DGVoodoo2 I unchecked "Force VSync" (I explain: game is more fluid if your computer can handle it).

In DGVoodoo2 I unchecked "Apply Phong shading when possible" (I explain: this setting can cause the game to crash to the desktop).

In ReShade my last settings:

Techniques=LumaSharpen,Unsharp,prod80_03_FilmicTonemap,ContrastAdaptiveSharpen,Pirate_Vibrance,prod80_02_Bloom

I'm very proud. To me it looks like the restoration of a masterpiece. Remember, from Windows 98, to Windows 10.

Hi. On the contrary. I myself like to see attempts to keep improving on the sim.

Right now I have a perfectly running FU3. I kept all settings on dgvoodoo2 on default except AA and AF.

We're saying the same things. By restoration I mean to meet today's standards.

Here I give a warning, about frame rate and ReShade:

ReShade causes an important bleeding of frame rate, cutting by half the frame rate. You need near 30 fps at least.

Try, instead of that, just to tweak inside dgvoodoo2. There are very interesting settings, like phong shading.
