- Requires CCGEP. Click here for Installation steps.
Latest Release: 2025-01-28
- Starting track temperature potential is now much higher, up to +20C ambient vs +10C before
- Off-path wetness now starts higher than on-path wetness to simulate from pre-session traffic ie. warmup before race. Previously, they always started at the same wetness.
- Bug: Misnamed "El Zonda.ccgep-mapping" needs to be renamed "ElZonda.ccgep-mapping" ie. remove the space. Will be fixed in the next release.
- Bug: Imola pattern conflicting with Keimola. Fix: Change "*keimola*" to "Keimola?GameData\Locations\Keimola\Keimola.gdb" in "UserData\Log\custom_weather\Keimola.ccgep-mapping". Will be fixed in next release.

Description
Enjoy real weather scenarios, based on real weather data from OpenWeatherMap.org, including realtime and slots-based weather, inspired by AMS2 Weather Slots, that just works in-game by new Rainfall selector options powered by the Crew Chief GTR2 Enhancements Plugin (CCGEP) by the The Iron Wolf.

Weather costs $10 per location from OpenWeatherMap.org. For that price, you get 40 years of data with hourly granularity. The data is open, can be freely shared, and has potential for re-use and repurposing for other mods, games, or software. I think it's good value.
Purchase OpenWeatherMap.org Marketplace > History Bulk weather data, download it, and share a link to the download.
If you do, check and double-check:
1. Date range: 1979-01-01 to 2023-12-31
2. Weather Parameters: All
3. Units: Kelvin

Questions
Is CrewChief Required?
- Technically, no, you don't actually need Crew Chief, itself, just the files that it installs. So, to get setup, get Crew Chief, set it up and get it to install its files, and you'll be good to go.
- If you're running beta, all you need are the beta files from discord. See link above for install steps including beta steps.
Does it work with any tracks?
- Yes, if weather data is already available, edit the UserData\Log\custom_weather\*.ccgep-mapping files and add a file with the Location's GDB name, without the extension. You can add one per line.
- Stars (*) can be used as wildcard characters. Instead of writing 3Anderstorp and SAnderstorp (for each GDB), you'd just write: *anderstorp*.
- Hints can be used when there are conflicts between multiple tracks: <GDB_NAME>?GameData\Locations\<TRACK>\<GDB_NAME>.gdb. For example, BHIM?GameData\Locations\WSCC1967_BrandsHatch\IMC\BHIM.gdb
- Mapping files are simple text files that you can edit with any text editor
How do I map a track without weather to a track with weather?
- Edit an existing mapping file with weather. For example, UserData\Log\custom_weather\Donington.ccgep-mapping
- Add a line including with a pattern that matches the Location GDB's file name.
-- For example, the pattern *wellwood* would match GameData\Locations\Wellwood\Wellwood.gdb
- The Wellwood track will now use Donington's weather
How does it work with the Rainfall selector?
- CCGEP adds Rainfall options in addition to the options already there so, after Changeable, you'll get new options like Realtime, 10min Slots, 15min Slots, 20min Slots, 30min Slots, 1hr Slots, 2hr Slots.
- Slots are random weather like Clear, Mostly Cloudy, Overcast, Light Rain, Moderate Rain, Storm, and Thunderstorm.
- If you're familiar with AMS2 weather slots, that's what they're intended to work like.
How can I save disk space?
- Saving space with multiple GTR2 drops
-- If you run multiple installations of GTR2:
-- Place the custom_weather folder in a common location (Ex. '''C:\GTR2CustomWeather''')
-- Edit '''CrewChief.INI''' and set '''customWeatherPath=C:\GTR2CustomWeather'''
- Saving space by keeping only the weather sets you use
-- If you only use, for example, Realtime and 20min Slots, then you can remove the other files
-- Ex. If you only use Realtime and 20min Slots then remove 10min-slots.zip, 15min-slots.zip, 30min-slots.zip, 60min-slots.zip, 120min-slots.zip from each of the folders
-- Note: If you then try to use Realtime or Slots by the in-game Rainfall selector that you don't have the files for then CCGEP will select a random weather file from among the files you do have.
- Saving space by keeping only August weather
-- You can save disk space by removing all UserData\Log\custom_weather\monthN folders except the '''month8''' folder indicated by setting customWeatherMode=8 in CrewChief.INI
-- Then all tracks will only use August weather
-- It must be cutomWeatherMode=8 and folder month8. No other months will work in this way.

Where can I find all these tracks?
- All of the supported tracks are available for GTR2 and I have downloaded them and tested them with weather, myself

Racing Tips
- Adjust WetGrip Levels for More Enjoyable Racing
-- Edit GDB files in GameData\Locations\Track folders and change RoadWetGrip to 0.93572998046875
--- Ex. GameData\Locations\_Cleveland2006\06Cleveland.gdb
--- The new WetGrip value is a systematically tuned value where the goal was less realism and more enjoyment bringing out the challenge and characteristic of wet tarmac driving without being either too overdone (not enough grip) or underdone (too much grip). It may not be realistic but it has provided many enjoyable races that still feel different than dry races.
- Adjust DryGrip Levels for More Enjoyable Racing
-- Edit GDB files in GameData\Locations\Track folders and change RoadDryGrip to 1.059765625
--- Ex. GameData\Locations\_Cleveland2006\06Cleveland.gdb
--- Tracks dry out after raining so having an accurate DryGrip level is important
--- I find this extra bit of grip feels more accurate to real life. Give it a try and see what you think.
Troubleshooting
- AI Pitstops DNFs and General Bugginess
-- Create a new profile. Seriously.
-- During testing, creating a new profile solved a problem where AI were being DNF'd in their first pitstop changing fuel and tyres and disappearing to the garage
-- After creating a new profile, AI were pitting and exiting flawlessly
