yippee
Had been waiting awhile and finally decided to see if I could figure out how to swap the new model we got with this game over the base form - ended up working fairly well. The only thing that isn't swapped is the weapon (I have no clue how to fix this - someone more experienced may be able to)
The in battle portrait and his model should be fully swapped.
to install-
Unzip the folder and drag the .pak into steamapps\common\SMT5V\Project\Content\Paks\~mods
