Are you downloading a free preset that you can use? Or someone's character preset so that you can see them in the game?
Also if you download a free preset that you can use just put the files in FeralHeart>My Presets and then into whatever file that the preset is set for.
Example: You download a public preset that anyone can use.
The maker of the preset made it in the preset 9 folders, you put the preset in the preset 9 folder too.
You also need to go in the game at the start up, press Tools, go to Preset Maker, go to whatever folder number the preset is in, and export it. Then go to the character you want to have that preset on and select Use Preset and select yoru preset. c:
To download markings it's really simple.
Download the markings that you want, copy or export all the .png files in Feral Heart>Media>Textures, put the .cfg file into the main Feral Heart folder and go in game and your markings should be there. :3
For items it's also really simple.
Download the item pack that you want, copy or export the .png files into Feral Heart>Media> Items, put the .cfg file into main Feral Heart folder, and then you should see the items in game.
