[Question] Nothing I've tried works for 4.2.2

[lawlcake15]

Every single Race to Race edit I've tried doesn't work. I've followed and triple checked the steps in EnArts video, tried using ClassicCleans pre-made model swap MPQ files, and yet nothing seems to work. I'm trying to make a GnF-ScF and a DrM-GoF, but after hours and hours of trying it just won't work. What am I doing wrong?

model swapping are works as through memory editing, as dbc editing (+/file swap). but for file swapping you need patch your "wow.exe".
perhaps you try to use not 4+ methods.
