Hello fellow flyers, Thought I'd open a new thread for this topic...was studying the environmentsys.ini file further this weekend and stumbled upon a few interesting discoveries that help with realism in FE/FE2. Weather speed and patterns for custom missions and campaigns should be tweaked in the relevant MSN files for missions/campaigns, but for single missions here are some good values to use to increase challenges and realism in game. It also gives slowly moving clouds/cloud patterns - set the time factor to x8 while parked at an airfield to notice this, although at windy settings it is noticeable at normal time factor (x1) too. I'm including four zipped environmentsys.ini files, for no wind, light wind, moderate wind, and strong wind patterns. Make a backup of your default environmentsys.ini file before installing. These files can be used with the weather/cloud mods I included with the ver. 8.6 update of the FM pack (to improve frame rates on low-end graphics cards). If you are using the Panama Red environmentsys.ini, make a backup of the original, then make four copies of the file and paste in the following settings. For no wind, include under [Weather]: WeatherAlt=4600 WeatherThickness=460 ContrailAlt=9200 WindGustingAmount=1.39 And under [baseWindSection]: BaseWindSpeed=0.0 BaseWindDirection=280 WindChange[01].ChangeTime=3.5 WindChange[01].ChangeChance=80 WindChange[01].SpeedAmount=18.06 WindChange[01].SpeedRate=36.12 WindChange[01].DirectionAmount=70.0 WindChange[01].DirectionRate=40.0 WindChange[02].ChangeTime=6.2 WindChange[02].ChangeChance=60 WindChange[02].SpeedAmount=22.22 WindChange[02].SpeedRate=44.44 WindChange[02].DirectionAmount=50.0 WindChange[02].DirectionRate=30.0 WindChange[03].ChangeTime=12.3 WindChange[03].ChangeChance=40 WindChange[03].SpeedAmount=26.39 WindChange[03].SpeedRate=52.78 WindChange[03].DirectionAmount=35.0 WindChange[03].DirectionRate=20.0 WindChange[04].ChangeTime=21.1 WindChange[04].ChangeChance=30 WindChange[04].SpeedAmount=30.56 WindChange[04].SpeedRate=61.12 WindChange[04].DirectionAmount=25.0 WindChange[04].DirectionRate=15.0 For light wind, use: [Weather] WeatherAlt=4600 WeatherThickness=460 ContrailAlt=9200 WindGustingAmount=11.11 [baseWindSection] BaseWindSpeed=4.17 BaseWindDirection=280 WindChange[01].ChangeTime=3.5 WindChange[01].ChangeChance=80 WindChange[01].SpeedAmount=25.00 WindChange[01].SpeedRate=50.00 WindChange[01].DirectionAmount=70.0 WindChange[01].DirectionRate=40.0 WindChange[02].ChangeTime=6.2 WindChange[02].ChangeChance=60 WindChange[02].SpeedAmount=27.78 WindChange[02].SpeedRate=55.56 WindChange[02].DirectionAmount=50.0 WindChange[02].DirectionRate=30.0 WindChange[03].ChangeTime=12.3 WindChange[03].ChangeChance=40 WindChange[03].SpeedAmount=33.33 WindChange[03].SpeedRate=66.66 WindChange[03].DirectionAmount=35.0 WindChange[03].DirectionRate=20.0 WindChange[04].ChangeTime=21.1 WindChange[04].ChangeChance=30 WindChange[04].SpeedAmount=38.89 WindChange[04].SpeedRate=77.78 WindChange[04].DirectionAmount=25.0 WindChange[04].DirectionRate=15.0 For moderate wind, use: [Weather] WeatherAlt=4600 WeatherThickness=460 ContrailAlt=9200 WindGustingAmount=16.67 [baseWindSection] BaseWindSpeed=6.94 BaseWindDirection=280 WindChange[01].ChangeTime=5.5 WindChange[01].ChangeChance=80 WindChange[01].SpeedAmount=30.56 WindChange[01].SpeedRate=61.12 WindChange[01].DirectionAmount=70.0 WindChange[01].DirectionRate=50.0 WindChange[02].ChangeTime=8.2 WindChange[02].ChangeChance=60 WindChange[02].SpeedAmount=33.33 WindChange[02].SpeedRate=66.66 WindChange[02].DirectionAmount=50.0 WindChange[02].DirectionRate=40.0 WindChange[03].ChangeTime=15.3 WindChange[03].ChangeChance=40 WindChange[03].SpeedAmount=41.67 WindChange[03].SpeedRate=83.34 WindChange[03].DirectionAmount=35.0 WindChange[03].DirectionRate=30.0 WindChange[04].ChangeTime=26.1 WindChange[04].ChangeChance=30 WindChange[04].SpeedAmount=45.83 WindChange[04].SpeedRate=91.66 WindChange[04].DirectionAmount=25.0 WindChange[04].DirectionRate=25.0 For strong wind, use: [Weather] WeatherAlt=4600 WeatherThickness=460 ContrailAlt=9200 WindGustingAmount=22.22 [baseWindSection] BaseWindSpeed=11.11 BaseWindDirection=280 WindChange[01].ChangeTime=5.5 WindChange[01].ChangeChance=80 WindChange[01].SpeedAmount=36.11 WindChange[01].SpeedRate=72.22 WindChange[01].DirectionAmount=70.0 WindChange[01].DirectionRate=50.0 WindChange[02].ChangeTime=8.2 WindChange[02].ChangeChance=60 WindChange[02].SpeedAmount=40.28 WindChange[02].SpeedRate=80.56 WindChange[02].DirectionAmount=50.0 WindChange[02].DirectionRate=40.0 WindChange[03].ChangeTime=15.3 WindChange[03].ChangeChance=40 WindChange[03].SpeedAmount=47.22 WindChange[03].SpeedRate=94.44 WindChange[03].DirectionAmount=35.0 WindChange[03].DirectionRate=30.0 WindChange[04].ChangeTime=26.1 WindChange[04].ChangeChance=30 WindChange[04].SpeedAmount=51.39 WindChange[04].SpeedRate=102.78 WindChange[04].DirectionAmount=25.0 WindChange[04].DirectionRate=25.0 The weather alt. value is typical of max. height of weather kites (2000-3000 meters) and weather balloons (3000-4500 meters) of the WWI period. 500 hPa (of modern weather forecasts) is at 5500 meters, 1000 hPa is at sea-level or slightly below ground depending on terrain. Typical WWI measurements would be to about 400 or 420 hPa if you look at the ceilings of the kites and balloons, which is about 4600 m alt. Weather "thickness" (a confusing entry that took me a while to figure out) is thus distance between 420 hPa and 1000 hPa, with the last zero removed from the value, giving 460. (For WWII and jet-age, use higher values for thickness, basically the weather alt. value with the final zero taken off, such as 1000 thickness for 10000 meters alt., 600 for 6000 meters alt. and so on.) Some of the effects of the modded environmentsys files are subtle, but improve realism. I did a few more ground loops than usual in a Fokk. E.IIa while trying to take off, with the moderate wind settings, especially if blipping the rotary engine off too frequently or not frequently enough - perhaps the result of wind gusts. Also, at moderate and strong wind settings, I found it more difficult to hit anything in a dogfight. You'll also notice that at higher wind settings, archie bursts and smoke trails, also engine exhausts tend to drift from time to time, or have zig-zag patterns. Will include these mods with a ver. 8.9 update of the FM pack. Happy flying, Von S
