The facade
Stone and timber walls, blue shutters, a bay window over the door and ivy climbing the observatory tower.
A free 3D editor where your AI agent builds game locations
Connect Claude Code or any MCP client, describe the place in plain words and watch it take shape in the viewport. Export GLB or FBX for Unity, Unreal Engine, Godot or Blender.
How it works
The Astronomer’s House. An AI agent built the whole scene in Cuberta, with no manual edits.
The Astronomer’s House
An AI agent built this whole scene in Cuberta without a single manual edit. Here it is from three more cameras.
The study
Inside, shelves of books, a desk under the window, a celestial globe on a stand and a star chart on the wall.
The front door
Up close: an arched wooden door under a lantern, climbing roses, and window boxes full of geraniums.
More scenes
Five more places AI agents built in Cuberta: a lighthouse, a winter lodge, a neon alley, a base on Mars and a temple in the jungle.
Watch an agent build a downtown
A screen recording of Claude Code working in Cuberta over MCP, sped up. It lays out the streets, raises the blocks and adjusts fog and light. Each step appears in the viewport as it happens.
Features
All features-
Terrain, trees and light
Hills, vegetation, sky and the time of day.
-
Your model library
Sign in to browse your Wandy3D library and community models, then drag them into the scene.
-
Any MCP agent
Claude Code is the usual start. Any client that speaks MCP can drive the scene, with your own model access.
-
Works offline
The editor and its bundled models, materials and skies run without a connection. The agent still needs its own.
-
Undo any step
Every action the agent takes goes into the history, and you can step back to any point.
-

Textures included. Opens in Unity, Unreal Engine, Godot, Blender and anything else that reads glTF or FBX.
Open it in your engine
Export GLB or FBX with textures and open the scene in Unity, Unreal Engine, Godot or Blender.

AI City Generator: Roads First, Then Blocks, Then Buildings
Generated cities look right from above and fall apart on foot. Road hierarchy, block sizes, frontage, junctions — the numbers that make a city read as a city.
Import a GLB Environment Into Unity and Make It Playable
A generated GLB or FBX location lands in Unity in minutes. Making it playable takes import settings, colliders and lighting — here is the whole path.
Importing an AI-Generated Level into Unreal Engine 5
You have a GLB of a whole district and a UE5 project. What to check on import: scale, Nanite, Lumen, collision, and why one big actor never streams.
