Same problem here my friend. I just got lucky this time. However I was actually fooled by it saying “Started”. Apparently it has already said that for a long time already…
They already added an option in developer mode to make the trees red, for an entirely different reason (to let us debug the trees density/distance). I think they should’ve made this a general feature to change the tree color to whatever we want, and/or randomized fall colors.
Yes it was started since a long time now.
However in one of the past Q&As, they mentioned that they found that seasons are “complicated” and another opinion on Asobo’s side was that Seasons for pilots are Weather…
I did not agree because the whole feature needs to be seen as visual immersion. Yes the ground tiles are aerial imagery but these I believe could be controlled using shaders (?) or any techniques modern engines like this one allow… Trees that change over time + leafless trees are not complicated to implement…
Snow is part of the season dynamics as well…
So as a first draft it must not be more complicated than that and I hope the Started = Continuing 
If Aces Studio did this in ESP ages ago, if LR are doing this in an outdated engine tech for their sim and if Epic did it a few years ago in Unreal Engine, then 100% sure Asobo are able to do that in MSFS engine 
Asobo once mentioned that they want to do seasons right, no half-baked solution. While this is a honourable approach, it is slightly amusing considering the fact that so many features of MSFS are exactly this: half-baked…
I only just noticed this. I hope it will still come. We need some kind of autumn/spring for sure.
What I don’t quite understand is if they want to do seasons right and think about the effect the seasons have on the weather what difference does that have to anything considering live weather is being injected into the sim so seasonal effects are already being taken care of by the real world?
I don’t quite understand what they’re getting at. I think most of us would just be glad to have seasons be a visual effect like the Bijan seasons mod. Certainly in the first instance anyway. Surely Asobo could do that relatively quickly and easily in the short term and then develop it further later on?
Current time of the year in the northern hemisphere is actually a great opportunity to bring a working Seasons engine to the sim, yet it looks like it won’t happen anytime soon. The dev’s focus is on some other stuff.
yeah,really sad!
Same here I do not agree about what are trying to do by collecting season photo aerial imagery, it does not exist that way, you want 10 petabytes of data? this will never happens in a global scale, inconsistent result will occur on many place even if they have the aerial photo, from quality and time of the day taken, there is already missing ground photo areal on certain part of the world as well, just to think about it, just a big mess. Collecting Mesh data is already hard, just figure the rest.
Using shaders to color ground with land class data is the most logic way, and trees coloration that match months\time transition and terrain for now. For bigger scale, this will require years need years to collect imagery, and will still be hit and miss, not accurate.
In my opinion, there will be no season before 3\4 years by collecting aerial season imagery and still will be not accurate on many area, missing data etc…
the next MSFS 2030 will have that unless a commercial entity that Asobo works with makes an alternative before that. After all, you don’t want to ruin a collaboration, do you?
And by the way. ORBX or Bijan does a really good job. In my opinion Bijan a less more cause its free streets. But there are so many data u need for a REAL seasoning. New sattalite images from all parts of the world in spring, summer, autumn and winter. And when its done, we all wait for MSFS 2040 cause we cant smell the flowers in netherlands and miss some seasons between the seasons 
I miss one or the other in MSFS, but when I look at old screenshots of P3D, for example, then we really have a hard, crass simulator available as far as the optics are concerned.
ORBX have a Season Addon for MSFS? I believe you meant REX (AccuSeason).
I bought Bijan initially and was happy with it but then found that many biome glitches around the world that were still not addressed. Then I got REX AccuSeason and I am very happy with it.
Yet AccuSeason does not control the ground tiles hues (with Masks as Bijan did with more or less successful effects). But AccuSeason shows a more consistent Biomes vs time of year and area of the world…
All in all, my constructive critic to MSFS as it is now and as a digital twin and a top-notch world engine, is to still have a static seasonal ambiance around the world while older gen sim engines embedded a dynamic seasonal system.
So I still think that it is was a surprising decision to stop/drop the seasons features in MSFS or to wait for an ideal solution that could not happen easily…
I still believe that as stated in this thread already, as a first quick win in MSFS native seasonal effects, they can use the same technique as REX uses, coupled with Shaders effects for ground tiles + controlling the snow coverage in a more refined way than the actual snow feature in MSFS (especially with real snow data).
I believe MSFS engine in 2023 needs such as dynamic aspects to reinforce its status as the most advanced out there vs competition that is way behind tech wise, yet with such dynamic features that are not yet in MSFS…
REX has this in Beta at the moment, hopefully it’ll be available soon.
Oh, thanks for the heads-up, great news, I did not know about it
i guess vanilla seasons solution is still being neglected by the dev
I don’t think so. It simply happens to be incredibly complex with the way scenery is generated in the sim. Changing the look of the trees is only like 10 percent of the work they’d need to do to make everything look authentic from any altitude. The major challenge is making the imagery dynamic. How are you going to change the colours of them as the year passes by? Essentially, you have to identify every field or grass area to know how they behave. I suspect we won’t see seasons until the sim uses all open street map data, which it doesn’t yet.
It’s complicated but not so much for the dev. They actually already do it with an automated shader application with snow coverage pulled up from live weather data with intensity level, so why not show a similar and more extensive approach for the seasons, which will basically re-render the ground textures and vegetation in accordance with predefined geo data.
x4 seasons so basically a 2 petabyte databank becomes 8
so ? i think disk space is the slightest of the issues here, in particular for a tech giant as ms.
Well I know drives get bigger and cheaper but 4000 2Tb drives for a flight sim would still mean a lot of maintainance
well if you can handle 2PB, you’ll also tackle 8.
We used to be very happy with our 1GB HDD back in nineties, now even a 2TB external SSD is not enough for most of us and we can handle it.
Oh I agree and as 100Tb commercial SSD’s are starting to appear I expect this will one day be implemented … but it’s still a major task for what it is little more than a game. Only A.I. could do it and so far that’s far from perfect.
