I realise it'll take a bit of work before things are properly compatible with 2024, but I tried copying the scenery folder over from my 2020 Community folder to my 2024 Community folder and it does get rid of the default (so it's doing something) but I get no buildings at all. I asked in a couple of FB groups and other people have this scenery working in 2024 using this technique.
Do I have to disable something in the default scenery? I'm using the standard version so I don't have an Asobo EGLL.
