CartoVox Delta V12
The climate behaves more like Earth's: rainforests are back in the equatorial lowlands, summer monsoons reach the edges of the subtropics, and tropical highlands are no longer deserts. Lakes are the right size: they evaporate, wet basins drain their giant lakes, and rift valleys hold chains of long, narrow lakes. Ocean trenches are narrow troughs, and a Trench depth of 0 gives none. Sculpt gains Built island and Wall tools, imported and drawn maps get their own Candidates, and zooming in shows real detail, down to each town's plan at its true size. Settlement Studio, Scene Studio and Travel put their map first, and an edit in one corner no longer renames towns on the far side.
The sea shapes every new world's coasts: glaciers carve fjords, drowned river valleys become long inlets and estuaries, waves cut bays between headlands, and barrier islands, lagoons and reefs rise offshore, all shown in a new Coast Lab. Land can sink below sea level, deserts have oases, and any nation can be given a strength, a naval reach and natural borders. Bring your own rivers and lakes into an imported map, see what Create made of every sentence of your description, and work in a calmer workspace with Sculpt docked beside the map.
Windows worlds that had stopped accepting changes restore, re-simulate and render again. Several GeoJSON files make one world, and plate lines painted over a picture of your map raise mountains where the plates collide. Rivers cut their valleys and local rebuilds wear your edit, ocean gyres bring warm currents, and the interface follows five languages almost everywhere.
Place key features and measured limits, import maps one decision at a time, edit rivers and nations, rebuild locally, plan campaigns and invite players on your local network. Seasonal soil water, ice domes, deltas and dunes shape the world; drafts and books have new ways to save and export.
Place a climate in plain words and see it on the cards, build imported and drawn worlds with rivers again, bring in Web Mercator and UTM maps, start on current Linux desktops, and build faster with spare memory.
Let your brief win over the planet type, watch lakes settle and rivers run downhill, map states and counties, play at a native tabletop, and finish a piece in Make.
Open offline starter worlds, choose your interface language, build on less memory, take a world to Foundry or your VTT, and bring in lore from World Anvil, Kanka, LegendKeeper or Campfire.
Run centuries of history over your world, build it in four clear steps, map volcanoes, caves and coasts, and bind an atlas with a cover, legend and gazetteer.
