🚘Build Your Own Car

⚠️ Warning: After the Prologue, mod packages will be activated. Please note that some features or content may change, be replaced, or behave differently once the mods are enabled. This guide assumes modded gameplay from that point forward.

✅ Step 1: Open the CarBuild Scene

  1. In Unity, go to:

    Level → Mod → CarBuild
  2. Once the scene is loaded, you’re ready to begin customizing your car.


✅ Step 2: Open the Car Setup Tool

  1. Go to:

    CST → Car Setup
  2. Enter a name for your custom car.

  3. Click "Create Car Folder" to initialize your car’s workspace.


✅ Step 3: Import Your Car Model

  1. Import your car body model into the scene or drag it into your car’s folder.

  2. Use the provided settings to fine-tune your build:

    • Wheelbase

    • Track Width

    • Pivot positions

    • Any other relevant settings

💡 Feel free to experiment with these to get the best visual and functional result.


✅ Step 4: Configure Wheels and Attachments

  1. Choose your default wheel setup.

  2. Set the attachment rules (e.g., wheel positions, bone anchors).


✅ Step 5: Build Your Car

  1. Once satisfied with everything, click:

  2. Your custom car is now prepared and processed!


✅ Step 6: Export Your Car

  1. Go to:

  2. Select your finished car from the list.

  3. Click Export.


✅ Step 7: Add the Exported Car to the Game

After exporting your car in Step 6, follow these instructions:

📂 Move to StreamingAssets

  1. Locate the exported car files (usually in your mod export or project output folder).

  2. Copy or move the entire car folder to the following directory in your game project:

    If the StreamingAssets folder doesn't exist yet, create it manually inside the Assets/ directory.

  3. (Optional) You can organize your cars in subfolders like:

💡 Why StreamingAssets?

Unity keeps everything in StreamingAssets/ untouched and accessible at runtime — your game can load these custom cars dynamically from disk.


✅ Step 8: Install Your Car into the Game

After exporting your car (see Step 6), do the following:

📂 Copy to the Game's StreamingAssets Folder

  1. Go to the folder where your car was exported.

  2. Copy the entire car folder (e.g., YourCarName).

  3. Paste it into the installed game's StreamingAssets folder, located at:

    🔸 If StreamingAssets\Cars doesn’t exist, create both folders manually.

  4. After pasting, the final path should look like this:

⚠️ Notes:

  • Do not rename any exported files or folders.

  • Ensure the folder includes all required data (models, prefabs, textures, etc.).

  • Admin permissions may be needed to copy files to Program Files (x86).


⚠️ Important Warning: No Modifying Scripts or Chassis Structure

As a modder, please adhere to the following guidelines to ensure compatibility, stability, and fairness within the community.

🚫 Do Not Modify Scripts

  • Scripts that are part of the core gameplay and car mechanics should not be altered or redistributed.

  • Modifying scripts may result in unintended bugs, conflicts with the base game, or even crashes.

  • Respect other modders' work and the integrity of the game’s functionality.

🚫 Do Not Modify the Chassis Structure

  • The chassis structure (such as vehicle skeletons, collision shapes, and bone setups) must remain untouched unless specifically stated by the game developers.

  • Changing the chassis structure can lead to severe problems:

    • Incorrect physics behavior

    • Incorrect collisions and interactions

    • Potential for breaking compatibility with other mods or game updates


✔️ What You Can Modify:

  • You’re free to customize the car's exterior, interior, textures, and imported other visual elements.

  • Feel free to create and share your own custom car builds, as long as the scripts and chassis structure remain intact.

🚨 Why This Is Important:

  • These rules help maintain game stability, protect compatibility across mods, and ensure everyone has a smooth modding experience.

  • We appreciate your creativity, and we want to preserve a positive and functional modding ecosystem for everyone.

✅ Done!

Your custom car is now installed in Car Service Together and should load in-game if everything is set up properly.
