Installation Methods

​
First Launch Setup

When you first launch Frosty, you’ll need to configure it for your games:
1

Profile selection window

On first launch, FrostyEditor will show the profile selection window.
A “profile” is Frosty’s term for a specific game. Each game has its own profile with custom settings.
2

Scan for games

Click “Scan for Games” to automatically detect installed Frostbite games on your system.Frosty will search common installation locations:
  • Origin/EA Desktop default paths
  • Steam library folders
  • Epic Games Store locations
3

Manual game selection

If automatic detection doesn’t find your game:
  1. Select the game profile from the list
  2. Click “Browse” to locate the game executable
  3. Navigate to your game’s installation folder
  4. Select the game’s .exe file
4

Cache generation

After selecting a game, Frosty will generate cache files:
  • Type Info Cache - Loads the game’s type system
  • Asset Cache - Indexes all game assets
  • MeshVariation Cache - Loads mesh variation data (if applicable)
Cache generation can take several minutes for large games. This only happens once per game version.
5

Ready to mod

Once caching completes, you can start creating or loading projects.

​
Configuration Files

Frosty stores configuration in your AppData folder for global access between builds: 
%APPDATA%/Local/Frosty/
├── FrostyEditor.json       # Editor settings
├── FrostyModManager.json   # Mod Manager settings
└── Cache/                  # Generated cache files
    ├── <GameProfile>/
    │   ├── TypeInfo.cache
    │   ├── Assets.cache
    │   └── MeshVariations.cache
Configuration files use JSON format (since v1.0.6). Legacy INI configs are automatically migrated.

​
