Define the World Logic
Describe the biomes, entities, factions, constraints and relationships that make your world work.
World design platform · Unity SDK
Build endless game worlds from a single creative vision.
Craft A World turns your game’s map vision — biomes, factions, settlements, roads, constraints and gameplay rules — into reusable templates, endless pseudo-maps, and fully rendered Unity terrain through an SDK.

Structured worlds
From world design to playable terrain
Most procedural tools generate terrain. Craft A World generates structured worlds. Define the rules of your world, save them as a template, generate endless valid map blueprints, then let the SDK render them inside your game engine.
Generate Endless Valid Maps
Create many pseudo-maps that satisfy your constraints, instead of random outputs that only look good from above.
Bind Meaning in Unity
Connect each biome and entity to textures, shaders, prefabs and gameplay assets. Then render the full 3D terrain through the SDK.
How it works
How Craft A World works
Six steps from a creative vision to a playable, in-engine world.
Describe your vision
Start with AI or build manually. Define the world’s biomes, entities, rules and constraints.
Save a reusable template
Refine the structure once. Your template becomes the design DNA for every generated world.
Generate pseudo-maps
Produce endless valid maps from the same template, each different, each respecting your rules.
Download or pull via API
Export maps into Unity manually, or pull them automatically from your game backend.
Bind assets once
Assign textures, shaders, prefabs, terrain rules and gameplay meaning to each biome and entity.
Render in-engine
The SDK turns pseudo-maps into full 3D terrain, ready for exploration, testing and gameplay.
Pseudo-maps
What is a pseudo-map?
A pseudo-map is a lightweight world blueprint. It does not try to store every tree, rock or terrain vertex. Instead, it defines the structure of the world: where biomes are, where settlements exist, how roads connect, where rivers and mountains appear, and which constraints were satisfied.
Your game gives that blueprint meaning through a binding profile. A forest cell becomes your forest shader, your tree prefabs, your ambience, your spawn rules and your gameplay logic.

Why it's different
Not another terrain noise generator
Craft A World starts from the rules of your world, not from a heightmap. The output is structured, validated and reusable.

Use cases
Built for games that need more than pretty terrain
Whether you ship a survival sandbox or a roguelite campaign, Craft A World gives you the structure to keep every generated world on-design.
Open-world survival
Generate large worlds with biomes, resources, roads, settlements and dangerous regions.
Strategy and colony games
Create balanced maps with factions, territories, chokepoints and resource constraints.
RPGs and adventure games
Place settlements, ruins, enemy zones, quest hubs and traversal routes with design intent.
Roguelite campaigns
Generate a fresh world per run while preserving the logic of your game.

Unity SDK
From blueprint to playable world inside Unity
Craft A World’s Unity SDK reads pseudo-maps and renders them using your own assets. You stay in control of the final look, performance profile and gameplay behavior.
- Runtime terrain generation
- Biome-based textures and shaders
- Entity and POI prefab placement
- Deterministic generation from seeds
- Large-world / chunk-friendly architecture
- API-ready map delivery
