As mentioned, the latest unstable test version includes the implementation of weather file processing in timetable mode.
Weather files allow definition of variable weather for a full day. There are three possible weather types : clear, precipitation (rain or snow) and fog. Weather files are text files in JSON format, with file extention weather-or, and must be stored in the route directory (new subdirectory weatherfiles).
The required weather file can be selected from the main menu. Selection is optional - if not selected, the normal default weather is used.

Thank you very much :sign_thanks:

I have to admit, I dont't know anything about env files etc and how OR simulates weather. Could someone in the know explain, how I get a beautiful day with blue sky and max some white clouds in OR? all I get atm is more or less gray, mostly overcast even with "summer" and "clear". Nevertheless thank you for the great weatherfile extension.

I missed this thread earlier but I think my question is still relevant:

Aside from the question of available programming resources to change code, is there anything about this neat new feature that would prohibit the weather file from being tied to specific non-timetable activities by means of adding a reference to the desired file in an .act file?

[Csantucci]

I don't know, but I don't think there are big obstacles.. However activity mode already has modes to change weather, both randomly and programmatically.

I was just thinking that what Rob created is both sophisticated and comprehensive and as such duplication in the OR code might be appropriate so as to implement an identical feature set in the two ways activities can be defines.

Hi The weather tool in timetable mode is very good and adds a touch of realism to the sim. I was wondering if the weather could be determined, could the time of sunrise and sunset (dawn/dusk etc) be controlled in a similar way.

But it's tied now globally to geographic coordinates of the route's <that You're usind> quad-tree, so auto-calculated by ORTS, taking in account the season...
Wait a minute: I guess, I understood, what You did mean...
The precise "day of the year"'s timings for astronomic events?
This way, the task will be just to have an opportunity of specifying the proper date at activity, or choose it during TT-options setting before game launching... In other words, more thin gradation, than present Four-seasonal?

I've seen somewhere the topic, where the Star-Calculator capabilities for using in ORTS were discussed.

I have been trying weather files in timetable mode and I really like it. However, I notice that the independent variable wind is set to zero if a weather file is loaded. This can be seen in the HUD. If in timetable mode and no weather file is set/loaded the independent wind exists.

Is it possible to fix this?

The weather code is split between default behaviour (which has a random wind component) and weather file behaviour (which currently cannot specify wind), hence a weather file always has zero wind right now

Although I am working on the wind code, I am not currently touching the separate weather file code, but it would make sense to consolidate these two separate behaviours in the future, and to add wind to weather files
