AI for game development: build 3D assets in Blender
Blender Bridge connects ChatGPT, Claude, Codex or Qwen Code to Blender. Describe a game prop or a level layout, and your AI can build the geometry, add materials and prepare an export for your engine. Start with a treasure chest, a modular corridor or a blockout to test scale. Refine the scene in chat or by hand.
Props and level blockouts
Give the AI the asset's purpose, style and dimensions. That might be a two-meter door, a chest for a mobile game or a set of wall modules that need to fit together. For a level, describe the rooms, routes and major objects. Check the layout with simple geometry first, then ask for details and materials. The AI chooses a suitable polygon count, UV unwrapping and texture baking itself; just name the style, dimensions and engine.
The AI works in a regular Blender scene. Ask it to save a .blend file so you can return to the models and keep developing your assets after exporting them.
Four prompts for your project
- "Make a low-poly treasure chest for Unity. Keep it under 2,000 triangles and one meter wide."
- "Block out an Unreal Engine level with a courtyard, two entrances and stairs to a balcony. Use meters."
- "Build modular corridor walls and corners for Godot on a two-meter grid. Keep each piece as a separate object."
- "Create a crate and a lamp for Roblox. Prepare an FBX for Roblox Studio, choose settings for the object and explain how to keep its size and orientation on import."
These are example briefs. Adjust the dimensions, triangle budget and object list to suit your game.
The workflow
You install the Blender Bridge app and connect your AI once. From then on, you create and change the scene in plain words in the chat — no code required.
- Connect your AI. To start a trial, verify your email and activate it, or sign in with an active subscription.
- Specify the engine, dimensions and style. Start with one asset or a simple layout.
- Ask the AI for a scene screenshot. Check the silhouette, proportions and placement of details.
- Refine it in chat: "widen the passage," "use fewer details" or "split the walls into modules."
- Ask it to save the
.blendfile and export the objects you need. Open the export in your engine.
Blender Bridge saves checkpoints of the AI's work. Return to an available checkpoint to try a different version of an asset or layout.
Formats, axes and scale
| Destination | What to request | What to check after importing |
|---|---|---|
| Unity | Unity FBX: Y up, −Z forward | Size next to your player character, materials and animation |
| Unreal Engine | Unreal FBX: Z up, −Y forward | Size in the level, orientation, materials and animation |
| Godot | Godot GLB | Size, object placement and materials |
| Roblox Studio | FBX for Roblox Studio — the AI chooses settings for the object | Size and orientation in Studio's import preview |
The Unity, Unreal Engine and Godot export presets account for scene scale, set the axes and report units, file size and warnings. Procedural materials may need baking before export. For Roblox, the AI prepares an FBX with settings for your object and explains how to import it into Studio.
Where the files go
Exports are saved in your project folder. When connected through the server, ask for a download link in the chat, then import the file into Unity, Unreal Engine, Godot or Roblox Studio. Keep the saved .blend file as the source for further changes.
