GTR2 Weather

Weather.txt

• Weather.txt is in UserData\Log
• It is automatically generated every race session
• To prevent it from being re-generated, set it read-only: Right Click > Properties > Attributes: Read-only
• Game generated weather.txt files are pretty boring and rarely exhibit any changing weather, even when Changeable weather is set in-game
• Use an app like Autosim Weather Generator for GTR2 to generate more plausible weather scenarios. It has a rather nice and intuitive visual, drag-and-drop style interface that anyone can grasp.

Changeable Weather

• Setting Rain to Changeable in-game is the only setting which will use Weather.txt

Threads

• Efforts to create weather file sets like we create new sky sets?
  • "Has there ever been an effort to create weather.txt files for all the kinds of weather conditions, something like how various people over the years have made sky textures for all the kinds of weather conditions?"
• Weather files?
• GTR2 not reading or generating weather.txt
• Changeable Weather Problem
• Cloudy skies, Rainy days in GTR2
• can't really see the dry line after a rain
  • "you need to wait around 8 laps then you will see what is shown on screenshots"
  • "What I still wonder ... does the track really gets dry after rain finally ?" [1]
    • "yes the track does indeed get dry but it takes some time but the more wet the track is the faster it will dry out..."
• Rainfall Settings Observations
  • List of Rainfall, Track, Ambient, Conditions, Forecast, Tyres Autoselected at various rain levels
• Off course there are dry and wet paths in the AIW files!
  • "At least in all base tracks from Simbin. It is defined as Lateral Offsets in the WP_path. First parameters are dry path and second are wet path."
• Revisiting the Changing Weather Patch Mod
  • "Problem: Temperance variance too wide: Can be 10C Ambient and 20C Track or 30C+ Ambient 40C+ Track"
  • "Problem: Temperature doesn't go up during the day and down during the night"
  • "Problem: Temperature doesn't go down with rain meaning wet tires overheat on a wet track because the track temperature doesn't go down being wet"
  • "Theory: I don't think these problems are solvable but a good work-around might be to replace the UserData\LOG\weather.txt with a 'good all-round' weather file that can address the first two issues (I think)."
  • "Modifying Average rain = 0.x to a higher value just gave me higher chance of constant rain. Think it just a multiplier of chance of a rain day?"
