    While this is an impressive piece of software it is not unlike other software that is available. As per a question previously posted here can you explain how it will define starting conditions for every single day of a race weekend? What this software appears to do is utilise the weather matrix rain, cloud and randomness settings and provides an easy way to see what these settings 'should' produce. Unless I am missing something it doesn't improve the weather modelling for the game. Certainly doesn't appear to give you options to change starting conditions of every single day of a race weekend or for each session.

    Not to take anything away from the hard work that has been put in to produce this program, its well laid out, easy to use and should help some people in creating server configuration files.
     
  2. Af far as I remember, it was possible to set the starting conditions for each session.
    Is it no longer possible?

    The "real weather" option in the championships always gives a 100% warm and clear dry race, not dynamic at all.
    Even setting it to custom weather and using the dynamic weather as ON and random weather as ON gives the same dry warm races all the time.

    Broken weather system, broken dynamic weather option and broken random weather option in single player at least.

    No idea what you're talking about, this is Monza 2019 championship with real weather setting, where it's supposed to have a high-ish chance of rain, and it does:

    Enabling dynamic weather in itself in custom mode will not guarantee variable weather unless you increase the variability above 50% and add some cloud, or keep the variability lower but add some rain to begin with.

    Nothing is broken.

    "Enabling dynamic weather in itself in custom mode will not guarantee variable weather unless you increase the variability above 50% and add some cloud, or keep the variability lower but add some rain to begin with."

    This may be it, in using the "random weather" option, it may be setting the variability and clouds too low for any chance of weather change to happen, but this is not visible to the player as they get blacked out.
    And so it plays out that each race is clear and warm due to low clouds.
    Perhaps it is not the variability but more how the randomness of the "random weather" option is not selecting a high enough clouds and wind setting to really be considered random?

    Literally first try with random enabled:

    But yeah, there is a moderate bias towards dry so it's not just various shades of rain.

    What variability do you recommend with random enabled pankykapus?

    I'd start with 60%. Generally speaking the high range is now a lot more usable since the last round of weather model updates with checks preventing the high likelihood of extremes, so don't be afraid to use it.

    Any tips on what weather settings to use to have the most chance of improving weather conditions when starting off with rain? With variability set to say 40, I get some variety, but rarely transitions to dry. With variability set to 100, I do get dry weather predictions, but there's also a larger chance of having really bad weather.

    Is there maybe something like the simracerWeatherConditions parameter but for single player? Or does anyone have any pointers on how the sineCoefficients work in the savegame files? I've played around with those, but I can't figure out how those 14 values correspond to time slots, if at all.

    Thanks for the fix on ambient never changing with "random weather"

    Doing the 2018 endurance championship on full length races again with "real" weather.
    Every session has been dry and blazing sun including the whole 24hrs of spa.
    One race left @ Barcelona now and yes, it's a sunny blue sky and hot tarmac again.
    Not a single drop of rain in the entire 2018 season set to real weather?

    Yes, if I remember well when I did the full 2018 season, the only one with rain was Misano. And it's a sprint race...
