The coast, lakes and volcanoes of Alaska - fjord arms and big lakes below steep mountains, cone volcanoes, glacier-carved cirques with tarns and braided rivers - at their real size, 10 x 10 km per map
48 maps of the coast, lakes and volcanoes of Alaska from real-world elevation data (DEM). Fjord arms and big lakes below steep coastal mountains, cone volcanoes up to 2,468 m of relief, glacier-carved cirques with tarns, braided rivers and rugged coastal ranges of Alaska. Each map covers 10.08 x 10.08 km (about 10 x 10 km, 102 square km) at 5 m between samples. Every Unity terrain sample is an original heightmap pixel - nothing is stretched or resampled - and 1 Unity unit is 1 metre.
✦ WHAT'S INSIDE
- 48 heightmaps - 16-bit PNG, 2017 x 2017 px, relief from 108 m to 2,468 m per map
- One Unity terrain per map - 2049 samples at the map's own 5 m spacing; the unused 32-sample strip at the edge is cut away with terrain holes
- 3 demo levels x 3 render pipelines - 9 ready scenes to fly or walk through: Volcano, Fjord Shore, Cirque Tarns
- Terrain Builder - one click turns any heightmap into a real-scale Unity terrain
- Alaska Fjords and Volcanoes ground look - 8 ground layers in 4K (meadow, forest floor, dry earth, scree, rock, gravel, snow, lake bed)
- Shore water - transparent fjord arms, big lakes and cirque tarns: clear at the shoreline, the bed visible in the shallows, darker water further out, rivers that follow the valley downhill, a thin moving shore film and wet ground just above the water, in Built-in, URP and HDRP
- Alaska in winter - the ground of the demo levels is painted from the real shape of each map: snow over the coastal slopes, alder twigs through the snow, deep snow on the cones, wind-scoured grey ash, dark scoria and black volcanic rock on the steepest walls
✦ FEATURES
- Huge real-world maps - 10 x 10 km of real ground in every map, at 5 m between samples: volcano cones, crater rims, cirques, fjord walls, deltas and braided river beds are in the data itself
- Exact scale - size and height range are in every file name and inside every PNG, and the builder reads them for you
- Anti-tiling terrain shaders - every layer blends three texture sizes by viewing distance, so no repeating patterns
- Cliffs without stretching - textures are projected from the side on steep faces, so walls show real rock texture instead of vertical streaks; flat ground is unchanged
- Verify - compares every terrain height with the original pixels
✦ PERFORMANCE
- Native 3840 x 2160 - no upscaling, demo scenes in player builds: HDRP 122-143 FPS · URP 159-216 FPS · Built-in 337-445 FPS (RTX 3090)
✦ DEMO CONTROLS
Mouse look · WASD move · Shift fast · G walk at 1.8 m eye height · F fly · N / P next / previous level · H help
✦ UNITY 2022.3 AND ABOVE
Built-in, URP and HDRP in one package. Tools > Lidar Terrains > Project Setup switches on terrain holes, and Shore Water Setup the depth and opaque textures the water reads, in your pipeline asset with one click. The Built-in Render Pipeline has no post-processing, so the Built-in demo levels look simpler than the URP and HDRP ones.
✦ USE CASES
Open-world games · flight and driving simulators · hiking, hunting and survival games · cinematics · terrain studies. The heightmaps also work in other tools: 16-bit PNG, north up, size and height range in the file name.
