Recently ive realised the transferring stuff from older forza games like Motorsport 7 is broken, just giving people a heads up if you cant seem to import old stuff from the older games. Hopefully this gets fixed soon as theres some stuff Id love to have on Horizon 4 from my Motorsport 7 designs :)

By broken you mean...?
All designs are available as full kits and individual pieces.

He means ‘not working anymore’ 🤷🏾

It’s recognised as a “known issue” by Forza Support and came about after the update to optimise the game for the new Series X/S consoles back in early Nov. last year:
Series 29 Update bugged

Since that update, players on Xbox One X/S consoles and PC are no longer able to import designs, vinyl groups or tunes from older titles. As far as I’m aware the function still works on the Series X & S but FM7 now crashes when people try to create anything in the vinyl editor.

Previous threads on the subject might give the OP more info:
Paint & decals not syncing?
Cannot import files from previous titles
Vinyl groups and full designs won’t sync from FH2,3 and FM5,6,7 to Forza Horizon 4
Horizon 4 - Can’t see my past liveries / decals
Importing Tunes from FM7
Files not syncing from FM7
Importing designs from older games, bug?

I’m sure there are more but you get the idea. As always, I’d still recommend the OP submits a ticket in the dwindling hope that the more they receive might just convince the Devs to give it a higher priority…
