How does it works

1. Once you start the executable, you'll be asked to set your path to your Fortnite .PAK files. Meanwhile a FModel subfolder will be created in your Documents folder.

2. Restart the executable, go to the AES Manager and add you AES Keys, click Load and select your .PAK file

• It will parse all Assets contained in the selected .PAK file with their respective path

3. Navigate through the tree to find the Asset you want

4. Clicking on Extract will extract the selected Asset to your Documents folder, it will also try to serialize it and will display information about it

• if the Asset is an ID:
  • Try to create an Icon with Name, Description, Rarity, Type and the Cosmetic Source
• if the Asset is a Texture:
  • Try to display the Asset as PNG
• if the Asset is a Sound:
  • Try to convert the Asset to OGG and play the sound
• if the Asset is a Bundle Of Challenges:
  • Try to create an Icon with all Challenges' Description, Count and the Reward
• if the Asset is a Font:
  • Try to convert the Asset to OTF

2. Enable Difference Mode

3. Click Load Difference

Update Mode

1. Enable Difference Mode, then Update Mode

Why FModel

This project is mainly based on what UModel can do, in a personalized way, if UModel doesn't work, as a temporary rescue solution. I'd highly suggest you to use UModel instead if you wanna use something made professionally.
