Workshop outfits for non-steam game
Is there someone who can help me? I don't have the steam version of Final Fintasy XV, so I manually downloaded some outfits from the steam workshop that I would like to include in the game, not being able to use the subscription system. However, I have no idea where they should be placed, or how to activate them. I tried to put them in a "mod" folder in the FFXV folder in the documents, but it doesn't work.
Plssss... I lost hours trying to figure out how to solve this problem, I found no answer in internet !
All outfit mods I downloaded have a .dat file and a .ffxvbinmod file inside it, how to understand where to put them? is the "subscribe" button the only way to activate them?
Thanks for any help
