File Structure Basics
Understanding AC's folder structure is essential for modding:
Important: Always extract mods completely before installing. Never place ZIP files directly in game folders.
Installing Car Mods
Step-by-step process:
- Download the car mod ZIP file from AC Supply
- Extract the ZIP to a temporary location
- Look for the car folder (usually named like
bmw_m3_e30) - Copy the entire car folder to
assettocorsa/content/cars/ - Launch Assetto Corsa and check if the car appears in the selection menu
Pro Tip:
Some cars may require specific DLC or Content Manager to work properly. Always read the mod description!
Installing Track Mods
Installation steps:
- Download and extract the track ZIP file
- Find the track folder (e.g.,
ks_laguna_seca) - Copy to
assettocorsa/content/tracks/ - If the track has multiple layouts, they'll all be in subdirectories
- Launch AC and find the track in track selection
Track Layouts:
Many tracks have multiple configurations (e.g., Nordschleife Tourist, GP). Each will appear as a separate option in-game.
Installing Skins
Skin installation:
- Download and extract the skin ZIP
- Identify which car the skin is for
- Navigate to
assettocorsa/content/cars/[car_name]/skins/ - Copy the skin folder (not individual files) into the skins directory
- The skin will appear when selecting that car in-game
Example Path:
assettocorsa/content/cars/bmw_m3_e30/skins/my_custom_skin/
Content Manager (Recommended)
Why use Content Manager?
- One-click mod installation by dragging ZIP files
- Automatic backup and mod management
- Preview mods before installing
- Update checking and version management
- Better UI than stock AC launcher
Installation with CM: Just drag any mod ZIP file onto Content Manager and it will automatically detect the type and install it to the correct location.
Common Issues & Fixes
Mod doesn't appear in-game
- Check that it's in the correct folder (cars/, tracks/, etc.)
- Make sure you extracted the ZIP file first
- Verify the folder structure is correct (not nested too deep)
- Restart Assetto Corsa completely
Game crashes when loading mod
- The mod may be corrupted - redownload it
- Check if you need DLC or dependencies
- Some mods require Content Manager or CSP (Custom Shaders Patch)
- Try running VirusTotal scan - file may be damaged
Missing textures (pink/black checkerboard)
- Texture files may be missing from the mod
- Check if mod requires additional texture packs
- Verify all files were extracted properly
Car sounds wrong or silent
- Some cars use generic sounds - install sound mods separately
- Check the car's sfx folder exists and has sound files
- May require FMOD sound bank installation
Recommended Tools

Custom Shaders Patch (CSP)
Visual enhancement mod. Required for many modern tracks and cars.

Creating Your Own Content
Getting started with mod creation:

- Each car has a
skins/folder with template files - Modify the textures, save as DDS, create preview.jpg
- Add ui_skin.json with skin name and details
Creating Cars (Advanced)
- Requires 3D modeling (Blender, 3ds Max)
- Export to FBX, convert with ksEditor
- Create physics files (.ini format)
- Add sounds, textures, and data files
Creating Tracks (Expert)
- 3D model the track surface and surroundings
- Create surface.ini for grip levels
- Generate AI racing line with ai_hints
- Add lighting and weather support
