Build with Bombs

Build with Bombs is an experimental Minecraft mod that generates houses by detonating TNT, using an AI model based on voxel diffusion.

What it does

The mod takes an unusual approach to building generation: a neural network trained on 3,000 buildings from the Greenfield 0.5.4 map creates a structure after a TNT blast. Generation takes up to 10 seconds on an RTX 4090.

• Generates houses as voxel structures
• Triggers generation via TNT detonation
• Creates buildings up to 5 stories
• Supports randomized layouts
• Uses Greenfield textures
• Limited to a 32×32×32 block cube
• Requires the Java edition of Minecraft

Download and installation

Build with Bombs is available on GitHub, where Timothy Barnes published the source code and files. It requires Minecraft Forge and Minecraft 1.18.2 or newer.

• Open the project page on GitHub
• Download the mod ZIP
• Install Minecraft Forge 1.18.2
• Place the mod in the mods folder
• Launch the game via Forge
• Make sure you have TNT in your inventory

Technical notes

• Neural network with 23M parameters
• Trained on an RTX 4090 (about 8 hours)
• Generates in ~5–10 seconds
• Uses diffusion (similar in concept to Stable Diffusion)
• Free to download; UI and docs are in English
