Ah sorry, for delay I thought I am subscribed to this thread. Ok, so for single player game case there are 2 components: rF2 plugin (for 64bit rF2 WeatherControlPlugin_x64.dll) and realtime server (program that gets data from Web) WeatherServer.exe. * From plugin readme: Copy the WeatherControlPlugin.dll (32bits) in the <rF2 Core>\Bin32\Plugins and WeatherControlPlugin_x64.dll (64bits) in the <rF2 Core>\Bin64\Plugins directory Copy WeatherControlPlugin.ini in the <rF2 Data>\UserData\<profile> directory (i.e. "C:\Users\Amphiprion\rFactor2Srv\Data\UserData\player") You do not need to change anything in .ini, for SP it is good as is. * For WeatherServer.exe, in .ini: // Weather Server ini file [RFACTOR2] // The directory containing the "core" directory CorePath=C:\Program Files (x86)\rFactor2 // The directory where GDB/AIW will be extracted GDBExtractPath=C:\Program Files (x86)\rFactor2\Plugins\TrackMap\Tracks Point directories to your locations. Usually somewhere under Steam\steamApps\common etc. * start weatherserver.exe and put dev key in. Allow Server through firewall if you get prompts. That's it. Now, keep server running. (Note: you don't need to click "Start Webserver" for SP). To verify it works: * In rF2 options, check if you see WeatherControlPuglin listed in Options/plugins. * Start a session, start race. If you have default settings you shall see plugin listed as started. * Pause game, alt+tab to check server program UI, you should see location loaded and real weather displayed. Hope this helps. Note, I am not at rF2 computer atm. So, there might be inaccuracies in my wording, but basic flow is that before running rF2, you need to launch (one more) external tool. I might check details this weekend if you are still stuck. This was quite confusing tool to figure out, notably that one doesn't need Static_HMI to get weather as is now (per my understanding). This is a real game changer tool for rF2 (Gerald, you Rock). Too bad it's no longer developed, but it mostly works. BTW, does anyone care to explain what "Collect Radar Image" does, does it build cloud map for game, or?
