@tamalien , so we can definitely confirm that the issue is evident, and it is difficult to understand how to solve - unless removing the little Procedural Buildings files from the World Updates, although it obviously cannot be a solution, but only a workaround because those files, if are present, there will be a reason.
This is also happening in Dublin and several other places.
Happens also on PC.
It looks like UK update is completely broken.

@Flobud , unluckily, not only UK. It seems a lot of areas all around the world, but in particular areas that received World Updates, are broken in some places and airports (for example, in USA too).

No.
Brief description of the issue:
Since Sim Update 5, the EGAC airport (Belfast City Airport) appears in this extremely simplified manner (as visible in the printscreen). No solutions trying to swith settings to Low and then to Ultra, as suggested in other posts.
The same problem is present in a lot of other areas and airports in the world and it seems to be only partially solved with a workaround, deleting the little PROCEDURAL BUILDINGS file from the UK World Update (same for the updates of other regions).
Problem is STILL PRESENT after World Update 6.
The problem also affects the surrounding areas, for example the city of Belfast, where many buildings appear as anonymous parallelepipeds.
Provide Screenshot(s)/video(s) of the issue encountered:
In the following two printscreens You can observe the situation âAS ISâ:

As I said, the issues is still present in 1.19.8.0 version (World Update 6).

I donât experience this and I am wondering if there are additional troubleshooting steps to take.
One thought that occurred to me is to get MSFS to rebuild all the scenery index files that may have become corrupted (assuming you havenât already tried this!)
The files concerned are found in
C:\Users\username\AppData\Local\Packages\Microsoft.FlightSimulator_8wekyb3d8bbwe\LocalCache\SceneryIndexes
again assuming you have the MS Store version of MSFS
Delete all the .dat files and then re-run MSFS. It may take longer to start as the files get rebuilt. It may be that this corrects the issue. (It also may be that it doesnât!) I would say it is worth a shot.

Me neither. I did a tour of Northern Ireland including Belfast last week and it looked very pretty indeed.

Sadly I see it. It has been present since sim update 5 beta testing. Even a re-install of Windows 10 and fresh install of the sim has not solved it - Edinburgh shows the same issue as well as other cities. Removing procedural buildings from the UK world update is a workaround of sorts.
There are several other threads on the same topic and perhaps the moderators (@tamalien) could merge and combine votes. Some examples:
Buildings are boxes after SU5 and 2 Hotfixes - Bugs & Issues / Scenery - Microsoft Flight Simulator Forums
(See pics of Castle Donnington early in that thread)
All settings ultra on a 10700K/RTX3090/32GbRAM/1Tb NVME. Fresh Windows 10. Fresh MSFS. No other apps installed. Iâve tried rolling cache on/off, switching settings Ultra->Low->Ultra - nothing helps. I believe its a server issue as at times it is worse than others. Ticket raised with zendesk.
âLegoâ land!
p.s. Windows 10 re-install was due to leaving Windows 11 Insider Program and not to solve this issue

@tamalien , I tried Your kind solution, removing the .dat files but it doesnât work.
Some days ago, I tried also a full reinstallation of MSFS, and neither this solved anything.
It is really strange that somebody, like me and @AboezD , encounter the same problem, and others donât.
@Duke76ITA and @AboezD
I am thinking along these same lines myself given the extra information that I am now seeing.
That isnât to say that there couldnât be any other reasons for this cause but I am at a loss, currently, to think what those may be. The server issue or connectivity issue (i.e. a possibility that for whatever reason the correct data is not making its way into the sim) seems to be like a perfectly plausible (and possibly even probable) explanation.
If that is the case then unless, on a particular PC, the issue can be diagnosed with connection issues/routes at the PC end it is very hard to see a way forward.
With regards to merging the threads listed I am going to enquire about this at my end to see what the best way forward might be.
I really do hope this issue can get resolved!
Note: I will try and get it seen by MS/Asobo as well to check if it is a server side issue!

After further thought it occurs to me Iâve never seen a correctly rendered Belfast/Edinburgh since SU5 but before that update I had no problems. Also Iâve flown at various times of day so presumably different loading. Surely these observations would cast doubt on it being server related or randomly youâd expect to see no issue from time to time.
I should also add Iâve made sure all packages up to date in content manager.

What does Edinburgh look like for you? Is it working?
Since SU5 there have been a number of issues there.
Missing terminal building at EGPH (Edinburgh airport)
The castle seems to be a lower Res model with no flag (it used to have the flag!)
Autogen buildings are now generic where previously they were fitting the scenery.
There is also a wall of death in Dublin that aircraft collide with. (Fly about 1000ft along the river = collide with invisible object and flight ends with black screen)
Could you check these and bring these to the attention of MS/Asobo also?
@somethingbrite Edinburgh has the SAME problem. Mine example about EGAC is only one of the great number of issues all around the UK, and not only in the UK.
@tamalien I suppose that, if it were a server issue, it should appear randomly, whereas it appears every time I try to fly on those areas.

@Duke76ITA Following my test of Edinburgh last night (and seeing the âblockyâ autogen there) I didnât have time to go and have another look at Belfast last night.
However, this morning I launched another flight over Belfast and for the first time ever I am now experiencing some of what you describe. I launched a flight over the city (rather than at an airport) and this is what I am seeing:
Exactly the same blocky buildings are appearing for me in some parts of the city. In other parts there is also the expected autogen of procedurally produced buildings I am used to seeing
I am also seeing areas where no ai buildings are being rendered of any type
All the above photos were taken from the drone cam in showcase mode.
However this doesnât seem to be a factor as I see the same thing from within the aircraft
I started a new flight, this time on runway 04 at EGAC and am seeing exactly the same thing
I was not experiencing any of this before prior to testing today.
I am on the North European server
Undeterred by this I exited MSFS and deleted the rollingcache.ccc file using windows explorer. When I relaunched MSFS I noticed the file had been rebuilt, so I deleted rollingcache again in General Options>data and turned off rolling cache and started a new flight from rwy 04 at EGAC. Same issue:
I then tried turning on rolling cache again (and to be sure set it at a different size to the previous size, 10 GiB instead of 8 GiB). I also changed to West European server and then started a similar flight from EGAC. I saw the same issues again.
I then tried turning OFF all online functionality in the sim from General Options>Data and clicked save. I started a new flight again from EGAC runway 04 and again I am seeing some areas with correct procedural buildings and some with the blocky ai: (I think this discounts the possibility that it is a server side issue)
and some areas with no buildings being created at all (as others decribe)
As a final test (for now) I re-enabled online functionality in MSFS. Once again deleted and reset rolling cache and left it on. I then exited MSFS and went to advanced app settings and clicked ârepair appâ
(Note donât click Reset app as this can delete all downloaded content that is stored in the defaul installation path)
I re-ran MSFS and launced the same flight from rwy 04 at EGAC on the North European server with live weather on (setting live weather on or off didnât seem to make a difference in previous tests as I had tried both)
This time limited success⊠The procedural buildings are back to where they should be and no more blocky ai buildings close to runway 04
However, moving the drone camera further afield from the airfield then I am seeing the same issue manifest itself, i.e blocky ai and missing buildings
and
Note in the lower part of this last screen shot there is evidence that at least some buildings are being correctly rendered as appropriate to this area as a result of the UK world update. Some areas have no buildings and some have blocky ai buildings. (This shot was about 3nm from where my aircraft is, on threshold of 04)
TL;DR from my investigations:
- I can reproduce this issue
- The areas it manifests itself is not consisent. In some cases I was getting blocky ai buildings that an app reset corrected. However when using the drone camera to move further away from the area I spawned into I was seeing new areas that had missing or blocky ai buildings
- The issue may well have been there for me all along and I never noticed it before as I wasnât paying close enough attention to ground scenery buildings in areas away from the runway as I would have been too high and never used the drone camera to get close enough to the ground to look at the nature of these buildings.
- The areas where this happens donât have to be consistent. An app reset can correct areas that previously had blocky ai buildings and replace them with the correct procedural ai buildings. However, the further away from the spawn point the more likely it is to see the issue manifest itself.

Youâve captured what I meant in my first post when I said the issue was inconsistent - itâs always present but just different areas. Youâll also find that toggling UK procedural buildings sometimes gives that church as a perfect render but then after a reboot itâs back as blocks.
I still think this is not just some UK cities but from other posts it may be limited to Northern Europe cities.

Further update for any developer that may read this.
I forced enabled the new âsafeâ mode by using task manger to stop the launch of MSFS.
On a subsequent re-run I enabled safe mode at the prompt.
I still see the same issues arising in safe mode which seems to confirm it is a game code issue rather than as a result of any add ons, marketplace or otherwise:
Blocky ai buildings:
and whole areas without any ai buildings:
intermingled with some correct procedurally generated ai buildings appropriate to the region:

I posted earlier that Belfast is fine for me: not any more! And the background satellite imagery has that horrible green hue.
