Frosty Editor is the main application for creating and editing mods for Frostbite engine games. It provides a comprehensive visual interface for browsing, modifying, and creating game assets.

​
Getting Started

​
Launching the Editor

1

Select Game Profile

Choose your game from the profile selector on launch. The editor supports multiple Frostbite titles including Battlefield, FIFA, Dragon Age, Mass Effect, and more.
2

Create or Open Project

Create a new project (Ctrl+N) or open an existing .fbproject file (Ctrl+O). Projects store all your modifications and settings.
3

Wait for Initialization

The editor will load the game’s asset database. This may take a few minutes on first launch.
Some game profiles require encryption keys. If prompted, provide the game’s encryption key file during initialization.

​
Core Features

​
Asset Explorer

The Data Explorer is the main interface for browsing game assets:
  • Tree View: Navigate assets organized by directory structure

    • EBX: Entity Blueprint XML files (game objects and configurations)
    • RES: Resource files (textures, meshes, audio)
    • CHUNK: Chunk resource files (streamed data)

​
Advanced Filtering

The filter supports multiple search modes: 
filename          # Contains search (default)
^filename         # Starts with search
type:MeshAsset    # Filter by asset type
modified:true     # Show only modified assets

​

Troubleshooting

​
Editor Won’t Launch

  • Verify .NET Framework 4.8 is installed

​
Missing Encryption Key

Some games require encryption keys:

  2. Place it in the game’s data directory
  3. The editor will prompt for it on launch

​
Project Won’t Load

  • Check project version compatibility
  • Try loading an autosave from the Autosave/ folder

​
Performance Issues

  • Close unused asset editor tabs
  • Disable Discord Rich Presence
