Usage in Thumbnails and Promotion

While reviewing the Island Creator rules, I found in the Creator Guide list that outfits are being provided. They are available at (Box), and there are about 114 of them.


I plan to create island thumbnails for promotion. I understand that the 144 officially provided images can be used, but my question is about the Fortnite character folder within UEFN. There are about 1,200 characters in it—can these characters be used to create thumbnails? If not, I’m curious why these characters are included in UEFN in the first place.
