SOLVED: Fanart not pulling images

[podonnell]

Is the fanart plugin reliant on TMDB IDs?

Yes, they use the same id.  Ex:
https://www.themoviedb.org/collection/98...uage=en-US
https://fanart.tv/movie/9818/mortal-kombat-collection/

In my testing collection images for both tmdb and fanart would not pull if there was not an associated TheMovieDb Box Set Id in the movie's metadata, which could happen if you use an external nfo manger and not jellyfin's default scrapers.

Hmm, so I do have a 'TheMovieDb Box Set Id' on my Mortal Kombat movies for the collection. It also auto-created the collection as well without me having to do anything.
For example it created: Jellyfin\Data\data\collections\Mortal Kombat Collection [boxset] and assigned both movies.
The movies themselves have artwork, but the Collection is missing the artwork. There's also no sign of a TheMovieDb Box Set Id on the collection metadata.
