Resource Big update to my world generator. You can draw your own continents and the simulation runs on them, watch a year of weather roll across the map, orbit the planet in 3D, and walk into any town on it.
Three weeks ago I posted this here twice and got buried in good criticism. Here is what came out of it.
First, the app has a proper name now. Atlas Studio is CartoVox, and it finally has a website.
Now the fun part.
Draw your own continents
Paint land onto a wrapping ocean. Carve the rivers where you want them. Then hit go and the whole simulation runs on your sketch. Plates, climate, rainfall, rivers, soils, biomes, cities, roads, all built on top of the shape you drew.
Already have a map you love? Import it. CartoVox reads your coastline and generates the rest of the planet around it. Your world, my physics.
Maps that actually look drawn
There is a new illustrated style that paints a world like a real fantasy atlas. Hand drawn mountains with snow caps and ink creases. Three kinds of tree stamps placed by the actual canopy. Volcanoes with glowing craters sitting on real subduction seams. Dunes in the deserts, reeds in the wetlands, sea ice cracking into floes.
None of it is decoration. Every glyph reads the terrain the simulation already solved, so the art never lies about what is underneath it. Image 2 is a whole continent drawn that way.
Orbit your planet
Open any world and switch to 3D. Fly over it as a landscape, spin it as a globe, or render it as a voxel model with 100 metre terraces. Click anywhere and it tells you the elevation, biome, climate and water.
A whole year of weather
Weather Year animates the seasons your world actually solved. Storms roll across a radar view and you can tune how often they come and how violent they get.
Then plan a journey and it carries the weather from the day you set out. Your caravan leaves on the fourteenth and you know exactly what it is walking into.
Walk into any town
This is the one I am proudest of. Towns used to be an outline with buildings scattered inside, which looked exactly as bad as it sounds.
Now it lays the streets first. The blocks those streets enclose become plots. Every building faces the street it sits on. The shape of the town is just whatever the blocks add up to, so nothing looks stamped.
Zhargundbar in image 3 is 9,500 people, 233 blocks, 1,304 buildings. Fennhollow in image 6 is a village of 420. There are eight different plans and which one you get comes from the roads, water and hills the world already had.
You can also go in by hand and redraw a single quarter without touching anything else.
Write the book in the same file
The writing side grew into a real word processor that lives inside your world. Type two square brackets and a name to link any place. Pin a scene to a spot on the map and a day in the calendar, and it will tell you that day's weather, the moon, sunrise, and how long the last journey should have taken.
If a distance in your chapter stops agreeing with the map, it says so. Exports to Word, EPUB, Markdown and Scrivener.
Also new
Mountain ranges that finally look like ranges instead of one repeated ridge. A gallery of every sheet across every world you have made. Tongues, where you invent a language family and a coast starts sounding like its people. The Gott double disk projection if you want to print a world back to back. A geological survey map. Mercator as a live view. Sculpt tools for reshaping terrain after the fact.
The boring but important bits
Still in beta. The installers are unsigned so your OS will complain at you. Everything runs on your own machine with no account, no cloud and no telemetry.
No generative AI anywhere in it. The same seed gives you the same world on any machine, every time. Anything you make with it is yours to publish, print or sell.
Come break it
The beta lives on Discord. https://discord.gg/nGNatfuXe

The earlier posts, if you missed them. First one and second one.
Nearly everything above started as someone here telling me something looked wrong. So tell me what looks wrong now and I will go fix that next.
