As it currently stands...
When one wishes to obtain the popular markings pack of Legendary, one must extract all files therein except the media.cfg file and place the files in the following location: FeralHeart > Media > Textures > Markings
Replace if asked.
Then, go back and extract the media.cfg file, placing it in the main FeralHeart directory.
Replace if asked.
My guess is that you've placed all files except the .cfg file in the wrong location, as Edolicious was a tad bit mistaken, there. (Arf, me hopes you mind me not correcting.)
Follow my instructions above, if you will. Perhaps then, the markings will show.
