Terrain Studio

Drag, add and remove coast dots, and give each dot its own beach, cliff or rocky shelf, with local beach width, cliff height, reefs and coast roughness. Alt-click picks several dots at once. Add coves, a lagoon, islets and reefs. Keep up to 12 named islands per place and switch between them in the picker. ⌕ DETECT TERRAIN: Already have land? Detect reads the ground that's there, finds every separate landmass and turns each into an editable island. Nothing changes until you press Apply. ⛰ SHAPES & RANGES: Drop mountains, domes, plateaus, craters, ridges and valleys that blend softly into the ground. Draw a mountain range as a line of crest points with a height on each peak. Flip any shape or range to cut pits and canyons. 🌊 NOISE STACK: Layer hills, ridged peaks, domain warp and dunes, each with its own strength, scale and seed. 🪨 ROCK FORMATIONS: Place arches, caves, overhangs and sea stacks, then rotate them and blend them into the ground. 💧 WATER: Place a spring and the river traces itself downhill into pools, rapids and waterfalls. Optional live water fills pools before they spill and carves the ground as it flows. Bake it into the place, pick a water look (glacier, tropical, hot spring with steam and bubbling…) and draw rivers right on the map. 🎨 MATERIALS & MASKS: Set beach, grass, heath, rock, cliff, snow and seabed by height and slope. Paint a mask (with invert) so every edit and brush only touches the ground you choose. 🌲 SCATTER: Grow grass, rocks and trees by material, height and slope. Pick from built-in models, scripted geometry or your own pictures, then preview live and apply. 🖌 SCULPT BRUSHES: Raise, smooth, flatten, terrace, rough noise, carve river bed, dig and tunnel. 🕳 CARVE CAVE: Paint a footprint into a hillside and it digs a real cave: a level floor, rough walls and a rock roof you can walk under. ✕ fills it back in. ↶ SAFE TO PLAY WITH: Full undo and redo, presets you can save, erosion bake, and a Restore button that gives the place its old ground back. The panel floats, docks and resizes, and the minimap comes in S, M and L with zoom.
