How to AutoBuild .Build Files in Build a Boat for Treasure (PC & Mobile Tutorial)

One of the most powerful features of the Butter BABFT Script is its ability to automatically place blocks and construct massive 3D structures—such as warplanes, giant mechs, anime characters, and hyper-detailed castles—in seconds using .build files.

In this guide, we walk you through downloading .build files from babft.com, setting up your executor workspace folder, and fixing common file loading issues on PC and Mobile.

1. Where to Get .Build Files

You can browse and download over 1,000+ custom Build a Boat for Treasure structures directly from our home page catalogue at babft.com. Every build file is community-tested and includes complete block counts and 3D previews.

2. Setting Up Your Executor Workspace Folder

For Butter Hub to load a .build file, the file must be placed inside your executor's designated workspace directory.

On PC (Solara, Xeno, Real, Wave, etc.):

1. Open your executor installation folder.
2. Locate the workspace folder.
3. Create a subfolder named Butter-Builds inside workspace (e.g. workspace/Butter-Builds/).
4. Copy your downloaded .build files into this folder.

On Mobile (Delta Android / iOS):

1. Open your Mobile File Manager (ZArchiver or CX File Explorer).
2. Navigate to Internal Storage → Delta → workspace.
3. Create the Butter-Builds folder and paste your .build files inside.

3. Loading & AutoBuilding in Roblox

1. Join a private or public server in Roblox Build a Boat for Treasure.
2. Execute the Butter Hub script loader from babft.com/script.html.
3. Click on the AutoBuilder tab.
4. Click Refresh Build List. Your saved .build files will appear in the drop-down menu!
5. Select your desired build and click Load & Start AutoBuild.

The script will place blocks with high accuracy, automatically handling rotation, color painting, and scaling!
