Solved Weather discrepacy between server host & clients
-
Hi community
This was already a problem in 4.35
But this problem still exists in 4.36Server host chooses probabilistic weather model.
During take off it is fair weather. During RTB server hosts weather is dynamically updated to poor weather.Server clients - all clients & not just one client - remains the same as fair weather as per take off.
There’s discrepancy in weather between server host & clients that they are not synced.
This means it’s not really possible to enjoy dynamic weather in multiplayer. Weather would only dynamically change on server host side but not on clients side at all.Following some pics taken in the same mission from flight lead & wingman perspective. Any idea what could of be wrong? Is this a bug or is there any setting that could prevent such situation?
It is easy to repro. Set weather model to probabilistic. Set min change interval to 600sec (10min) and max change interval to 1200sec (20min). Set the probability of poor weather to 94% with the rest being 2% each. Start from Fair current weather. Fly in multiplayer, take off and enjoy some training and once RTB you would see that host would enter poor weather vs. clients all stay in fair weather. ATIS from #2 wingman who is responsible for listening also have info unchanged & stay the same as FAIR which confuses flight lead (server host).

Bug Found and fixed (very old bug , at least 4.33)
Bug in Deterministic and Probabilistic
Maps are OK
Check fix next release

There’s probably a problem to solve, but as far as I understand, if you want realistic weather, it’s Map Model you should expect something from. And a set of real weather maps from F4Wx 1.05.

@LorikEolmin Thanks for the feedback.
What i’m saying has nothing really to do with using realistic weather or not.
I am just using the default probabilistic weather model and would just like to have some different weather so that T/O and RTB could be more interesting and not always boring same weather, that’s all.A quick repro just done - swapping server host role and can confirm that only the server host will have dynamic probabilistic weather changes and all clients would stay current as per time of T/O / static / unchanged
Pics taken at exactly same time from different perspective for comparison as follow again to show what i’m trying to say

@LorikEolmin Thanks for the feedback.
Yes, understood, just don’t expect to have much interest in that question, not more than you will have in enhancing Instant Action or the easy mode of AAR.

@LorikEolmin Would be a big pity if the probabilistic weather model could only be enjoyed in single player. In multiplayer, aside from having different weather between the host & clients, in fact if all participants tune to listen to ATIS, the server host will also get a different ATIS content from the rest of participants.
Great weather engine design and good intention and it’s meant to be as real as it gets with this exciting feature. Weather is definitely a big interesting factor when it comes to aviation. Would be really surprise to learn if this issue isn’t much of interest to the serious-flying virtual pilots.

The only model that allows different weather through the whole map is Map Model. This simple reason makes Deterministic and Probabilistic, as Mav-jp once said, “a thing of the past”.
Map Model also means the whole weather map is updated real time. There’s nothing Map Model would envy to the two others.

@LorikEolmin I see. Thanks for the clarification. I experienced same problem before in 4.35 with map model. Since 4.36 implements new fog layer, i have not tried customize map model from F4Wx yet as not sure if they are compatible. Will give it a try and see how it goes in 4.36

Except for random weather. For people who just want to randomize the weather, without influencing it in any way (kinda like in real life), probabilistic seems to be the only choice.

Random weather is an intriguing idea. It supposes that there is a way to generate random weather that is satisfying; it depends where you place your satisfaction. If you consider a set of maps as a trick or a cheat (even though weather forecast is something real, and though you don’t necessarily look at the pictures) and want a random engine to generate weather instead, then you have to consider what you lose on the way. My satisfaction is so placed that I can’t be happy with a homogeneous weather on the whole map (not to mention, a homogeneous weather that could be totally decorrelated with the peculiarities of the geographic area).

Finally there was also a bug in FMAPS
this is found and fixed for next release
