Castle Generator

Castle Generator builds complete castles inside Blender, ready for film, VFX and games: curtain walls with battlements, towers, a gatehouse with portcullis and drawbridge, a keep, courtyard buildings, siege engines, a moat and the ground they stand on. Pick one of 30 styles modeled on real fortifications, then change anything. Every part is a slider, a choice or a switch, and the castle rebuilds live as you drag.

Walk inside. The keep, the towers and the courtyard halls are hollow buildings with real windows and arrow loops cut through thick walls, timber floors on beams, stone stairs climbing the walls, and furnished rooms: a great hall with long tables, a throne, a roaring fireplace, tapestries and candle chandeliers, bedchambers, kitchens, storerooms full of barrels and crates, guard rooms and a fully stocked armory with weapon racks, armour stands and shields.

Draw your own walls with a curve and the towers, gate and battlements follow it, or let the walls climb any terrain mesh you pick. Choose a rectangle, polygon, oval, irregular hilltop plan, star fort or concentric double ring, and make it new, weathered or a roofless ruin with broken walls and fallen rubble.

The styles span ten centuries and three continents: motte-and-bailey, Viking ring fort, Roman castrum, Norman keep, shell keep, concentric and Edwardian castles, Crusader fortress, Moorish alcazaba, Spanish castillo, French chateau-fort, Carcassonne, German Burg, Teutonic brick castle, Russian kremlin, Scottish tower house, Japanese castle, Chinese city gate, Korean fortress, Great Wall, Indian hill fort, Mughal red fort, desert kasbah, star fort, Martello tower and fantasy citadels.
