The people making the liveries megapack have changed their delivery method but if you follow the old link you still end up at megapack v8. The liveries are now on Google Drive as distinct folders. You just select the ones you want, download them and drop them in the Community folder. Any new liveries will only be there.
I am not affiliated with them in any way, I just went onto the MSFS Liveries Discord and was told there. There’s an FAQ there as well. I thought I’d share it here because I could barely find anything about this on the forums.
and with this google drive method ur community folder will explode coz now every livery will be right under /community/ instead having an aircraft folder over it …
What I linked to is called “Clink’s Megapack X” on the Discord of which Clink seems to be the owner. There is also an all-in-one folder in the Google Drive but the last time I checked it was too big for Google’s download zipping mechanism.
