Edit: The Mod is now working properly!
Thanks for updating with UE4, I would like to test these because none of the others seem to be working atm, so I tried this free mod, it doesn't seem to work with me with the hongmoon outfit or the earrings.
Only tried the Yousa Sweater without the long hair.
First I tried pasting the content of the .rar file into a new folder called "Mod" in this direction BnS_UE4\BNSR\Content\Paks\
It didn't work, I changed the name of the folder to "Mods" instead but it didn't work. Lastly I tried pasting the content right in the paks folder without creating a folder and then doing both simultaneously (having both the content of the rar file in a Mod folder and leaving the same content in the Paks folder too) but nothing changes.
Perhaps am I'm missing some crucial information or option that I need to enable/disable ? Or if someone else is running this mod smoothly perhaps the problem is on my end, I'm playing in the NA server btw.
