I recently started a project where I decided to spice it up a bit, I would create some custom paintings to have instead of the default ones. I created a new back texture and several paintings. I was able to create the zipped file, and it shows up in my resource packs. In game, though, only the back texture works. The new paintings I had created will not show up and just show as the defaults. Is there something special you have to do for paintings?
