TerraNova Engine

Create worlds, draw maps, and build whatever you imagine

Terranova Engine is a world-building tool for planets and maps. Create celestial bodies and draw maps — as a 3D sphere or flat 2D cartography, the choice is yours; place landmarks freely and give them emblems or totems; craft and import planet textures; plan routes and navigate. Build any map or planet you can imagine.

Create celestial bodies, draw freely

Build from scratch — stars, planets, moons, dwarf planets, asteroids, comets... set their size, appearance and orbit any way you like.
3D sphere / 2D flat dual view — switch with one key, and zoom, rotate and pan smoothly, choosing between globe view and flat cartography.
Build it your way — whether it is a map or a whole planet, it is under your control.

Place landmarks freely, give them unique totems

Place landmarks anywhere — create landmarks at any spot on the map and mark every place.
Emblems and totems — a symbol library plus a layer editor to paint a one-of-a-kind emblem or totem for every landmark.
Huge landmark variety — cities, mountains, rivers, lakes, countries, provinces, airports, ruins, military bases and 30+ more types.
Quick lookup — keyword search, category filters and favourites, with multilingual place names translated automatically.

Craft and import planet textures

Built-in skins — Default, HD, Night, Hydrology, Terrain, World Map, Borders, Blank and more.
Craft and import custom textures — height maps and high-resolution tiles, plus longitude/latitude offsets and flips for fine-grained control over every face.

Routes and navigation

Route planning — set start and end points, get the total distance and estimated travel time across 10 modes: walking, oxcart, horse, bicycle, car, train, high-speed rail, airliner, fighter jet and missile.
Sticker annotation — drop text or image stickers anywhere to record your discoveries.

Realistic celestial simulation

Rich celestial bodies — black holes, neutron stars, pulsars, white dwarfs, red giants, and nebulae, galaxies, clusters and constellations.
True orbital mechanics — rotation and revolution, orbital inclination, ascending node, argument of periapsis, eccentricity and tidal locking.
Immersive visuals — realistic lighting, atmosphere, clouds, magnetosphere and planetary rings; black-hole event horizons, accretion disks and gravitational lensing, pulsar beams and comet tails.
