GWX2 - RealWeatherFix Mod

[Reece]

Yes it does seem to get stuck sometimes, remember that if you load a prior save those weather conditions will persist for atleast 4 days!!

its dopped down to 7 now but it still hasnt went below 5 yet.

Based upon some recent testing, these are my new recommended .mis file settings for the RWF and GWX 2.1:

Fog=0
FogRand=2
Clouds=1
CloudsRand=2
Precip=0
PrecipRand=1
WindHeading=0
WindSpeed=4.000000
WindRand=2
WeatherRndInterval=2

Testing was done by setting all of the Rand values to the same number (0, 1, or 2) and observing effects for a two week patrol period. At values of 0 or 1, weather changes were slower and "stickier." In other words, with each change in the weather, a particular weather value (clouds, rain, fog, or wind) was more likely to remain at the same setting as before. In practical terms, this seems to result in less dynamic weather over the course of a patrol.

Interestingly, precipitation seemed to be most influenced by changes in the Rand value. At a setting of 0, I noticed one patrol with NO rain at all. On the other hand, at a setting of 2, I experienced 4 days of rain over a 16 day period. A setting of PrecipRand = 1 seemed to give the best results, with 2 days of rain (non-consecutive) over a 16 day period.

Wind speed, of course, seems to be the most troublesome value to set to an acceptable level. However, I definitely DO NOT recommend you leave the WindRand setting to a value of either 0 or 1. At these settings, wind speed seems to be much more likely to stay at the same value for several days in a row! A WindRand setting of 2 seems to allow for the most dynamic changes in wind speed over a two week patrol.

Finally, with WeatherRndInterval = 2, my first weather change was observed approximately 15 hours after leaving port from Wilhelmshaven in August of 1939. By the end of my patrol, weather changes were occuring approximately 24 hours after the previous weather change. Setting WRI to a value higher than 2 should result in weather changes taking place somewhat more slowly.

One word of caution: I have not yet tested these new settings on a "real" patrol. Also, keep in mind that as difool2 pointed out, weather changes vary from season to season and also according to longitude and latitude! All of my testing took place in the North Atlantic, so don't come crying to me if you don't get acceptable results while cruising in the Indian Ocean!

Ok. I have questions about this mod:
1. How does it work? When will I install it I must begin patrol from base to see weather changes or it works with my 'on sea' save games?
2. I have already GWX 16km atmo mod installed. When I try install RealWeatherFix Mod
JSGME showed message about changes in scene.dat made by GWX 16km atmo mod and than I have uninstall GWX 16km atmo mod before RealWeatherFix Mod instalation. Is it necessary to unsinstall GWX 16km atmo mod first, or both mods can work together without any bugs?

OuNiS, do you have GWX 2.1? If you do, you don't have to install the RealWeatherFix, because it's included in the GWX.

[Subtype Zero]

Correct. The RealWeatherFix mod is included with GWX 2.1. However, in the post above I am talking about the .mis files located in the data/campaigns/campaign folder. RWF installs with default .mis files. I'm suggesting in my post above to try some differerent settings in these files to see if you get somewhat better weather behavior. I believe that the new settings in the .mis files take effect after your next save, although it's hard to tell, and it might not take effect until the start of your next patrol.

Thx for advice!
I have GWX 2.0. May I simply upgrade it to version 2.1?

Yes...download it from my sig and install it directly over 2.0

Pleased to hear it

I tried the new settings (edited all 3 mis files) Subtype Zero, on a new patrol and had 12 days of solid rain, heavy fog, 15k winds without reloading! your first settings seem to be the best IMO.

[Subtype Zero]

Yikes! Haven't seen that before! Did you make sure that PrecipRand = 1, instead of 2?

your first settings seem to be the best IMO.

Do you mean my revised setting or the original RWF setting?

[Reece]

Yes, for sure!

Do you mean my revised setting or the original RWF setting?

Actually it was these, not sure where they came from, GWX original maybe?:

Fog=0
FogRand=0
Clouds=0
CloudsRand=0
Precip=0
PrecipRand=0
WindHeading=0
WindSpeed=6.000000
WindRand=0
WeatherRndInterval=5

Might have to try your revised version.
I'm starting to think that these settings (mis files) don't do much, however the alteration to Scene.dat file seems to have more of an effect (RealWeatherFix.exe)!

Edit: This could be a querk with the SH4 Scene.dat!!

[Subtype Zero]

SH4? Que?

RWF is designed for SH3. Hasn't been tested on SH4. Don't know what effect importing scene.dat from SH4 into SH3 would do. Probably not good for RWF.

[Reece]

I didn't actually use the exe, I manually changed the Scene.dat to the settings RWF would have changed, believe me, I got it right:

WindHeadingChangeSpeed to 0.01
WindSpeedChangeSpeed to 0.0015
ChangeTimeMin to 2.00
ChangeTimeMax to 5.00
RandomWindSpeedMax to 0.005
RandomWindSpeedVariationSpeed to 0.007
RandomWindHeadingVariationSpeed to 0.007
RainIntensityChangeSpeed to 0.017

Just might be some other code I don't know about!!
