🤯 WHAT IF YOU COULD BUILD AN ENTIRE MEDIEVAL CITY WITH AI?

Someone is using Claude Opus 5.5 + Blender + Unreal Engine to create a fully explorable walled city.

And the crazy part?

Every street is walkable. Every district is planned. Even the smallest details have a place.

Here's how the workflow works:

01. Connect the tools
Run Opus 5.5 on high effort and connect Unreal Engine and Blender through MCP.

02. Design the city first
Map out the walls, gates, main roads, districts, and central plaza before building anything.

03. Build a modular asset library
Use Blender to create reusable walls, towers, rooftops, houses, and market stalls.

04. Generate architectural variations
Create 10–15 different house designs using the same modular kit, with different materials, roof colors, and structures.

05. Populate the districts
Fill the streets with houses, gardens, orchards, and market areas.

06. Place the landmarks
Add the cathedral, fountains, and marketplace exactly where they belong on the original map.

07. Create the player character
Generate a character using Tripo AI and bring it into Unreal Engine.

08. Explore and refine
Switch to third-person mode, walk through every street, identify problems, and fix anything that looks wrong up close.

BUT HERE'S THE MOST IMPORTANT PART:

Don't start by building houses.

Start by planning the roads.

The streets determine where everything belongs. Once the layout is established, the buildings, districts, and landmarks can fit naturally into the city.

Claude handles much of the construction.

You decide the city's vision, choose the important landmarks, and judge whether the final world actually feels alive.

We're getting closer to a future where describing a world is enough to start building it.

AI-assisted game development is getting seriously wild.
