Cartosketch vs. WorldPainter: Generating Real Places vs. Painting Custom Terrain

WorldPainter comes up in every search about custom Minecraft worlds, and deservedly so — it has been the standard desktop tool for sculpting terrain for over a decade. But "custom world" hides two very different jobs. If the world in your head is invented — a fantasy continent, a mega-build canvas — WorldPainter is your tool. If the world you want is real — your street, your campus, a city you love — painting it by hand is the long way around. That's the job Cartosketch automates.

Cartosketch's Minecraft worlds are generated from OpenStreetMap data (map data © OpenStreetMap contributors) with an engine built on the open-source Arnis project — every street and building comes from the real map, not from an AI's imagination. Cartosketch is not affiliated with Mojang or Microsoft.

Two different questions

WorldPainter answers: "What terrain do I want to create?" You install a desktop application, learn brushes, layers, and biome painting, and shape a world with artistic control. Real-world data enters only if you go find it yourself — it can import height maps, so with an elevation dataset you can reproduce real terrain. But that path is manual, and it stops at terrain: no streets, no buildings, no land use.

Cartosketch answers: "Which real place do I want to play in?" You search a location, frame the area on a live map, and the server converts the real map data into a world — buildings, roads, parks, rivers, and the actual elevation profile — with three generation modes (Objects + Terrain, Objects only, Terrain only) depending on how much of the real landscape you want.

Side by side

The last row deserves honesty in both directions: WorldPainter is free (donation-supported) and Cartosketch bills by area — 1 credit per 10 km², with a free credit on signup that covers a neighborhood-sized world and automatic refunds on failed runs.

Where WorldPainter is the better fit

• Invented worlds. Fantasy continents, adventure-map landscapes, spawn regions for servers — anything that never existed on a map.
• Total control. Every brush stroke is yours: biome boundaries, cave layers, custom trees, resource distribution.
• Terrain-first megaprojects where you'll spend weeks in an editor anyway.

Where Cartosketch is the better fit

• A specific real place. Your neighborhood, your school, a landmark, a whole city district — generated in minutes with everything where it really is (step-by-step guide).
• No desktop tooling. It runs in the browser; the output is a normal save you import into Java or Bedrock.
• Real terrain as a starting canvas. Terrain-only mode gives you a real gorge, volcano, or mountain range to build on — no height-map hunting.

And the hybrid path is real: generate the true-to-life base with Cartosketch, then open it in an editor for artistic refinement. The output is a standard world file, so nothing locks you out of the modding toolchain.

Frequently asked questions

Can WorldPainter recreate my real city?

Only the terrain, and only if you import elevation data yourself. Buildings, streets, and land use would all be manual work. That automated conversion of map data into blocks is exactly what Cartosketch does.

Can I edit a Cartosketch world afterwards?

Yes — it is a standard world file. It loads in the game, in MCEdit-style editors, and on servers like any other save.

Which handles Bedrock better?

WorldPainter targets Java; getting its output onto Bedrock means third-party conversion. Cartosketch exports a Bedrock .mcworld directly, alongside Java and Luanti.

How much does a Cartosketch world cost?

1 credit per 10 km² of selected area, minimum 1 credit. A new account includes a free credit — enough for a neighborhood — and failed generations are refunded automatically.

Is either tool official?

No. Both produce standard world files; neither is affiliated with Mojang or Microsoft.
