INSTRUCTIONS: (Side note: You MUST have WinRAR or Zip to download these Markings) Open up the textures folder and right click and drag over all of the markings. Then, click "start" at the bottom left corner of your computer screen. Go to "My Computer" and click "Local Disk (C:)" got to your Feral Heart folder. Click "Media" then "Textures" and drag/paste all of the markings into the folder. Next, go back to the .cgf file and drag it into your MAIN FeralHeart folder. DO NOT copy it into the textures folder, or the media, my_presets ect. Next, open up your Game, and have fun! ^^ - Taken from the DeviantArt page ^_^
As for when you are making your character, after you make sure that you have put everything in the right places, you will see them on the character creation screen just like you see the game's built in markings ^_^ Your list for markings will just be a lot longer. And when you get in the game, you will be able to see everyone's markings.
