PC - Gamepass Livery Mods not working
By - highvoltage74
Right now they work only if the path is in C: drive. It's a known issue. The devs are looking into it.
As a workaround you can still have the game installed in D: or E: etc. and you can recreate in C: the exact folder structure to the livery folder and drop the liveries there.
I tried that and it still won't work. I can wait for the patch though
