Italian Alps Peaks & Valleys Real-World Terrains 8.7 km

The deep trough valleys, serrated ridges, cirques and mountain lakes of the Italian Alps at their real size, at 4.34 m resolution

37 heightmaps of the Italian Alps from real-world elevation data (DEM). Deep glacial trough valleys with flat floors, serrated granite and gneiss ridges, cirques, firn patches on the highest tops and small mountain lakes of the central Italian Alps. Each map covers 8.749 x 8.749 km (about 8.7 x 8.7 km, 77 square km) at 4.34 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

• 37 heightmaps - 16-bit PNG, 2017 x 2017 px, relief from 1,285 m to 2,381 m per map
• One Unity terrain per map - 2049 samples at the map's own 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: Alpine Valley Lake, High Peaks and Firn, Trough Valley and Ridge
• Terrain Builder - one click turns any heightmap into a real-scale Unity terrain
• Alps ground look - 8 ground layers in 4K (meadow, forest floor, dry earth, scree, rock, gravel, snow, lake bed)
• Water - lakes with natural waves travelling across the surface, soft shorelines and deeper water towards the middle, in Built-in, URP and HDRP
• Snow - old snow and firn only on the highest tops, placed from the real shape of the mountains in the demo levels

​

✦ FEATURES

• Exact scale - size and height range are in every file name and inside every PNG, and the builder reads them for you
• 4.34 m resolution - gullies, ridges, cirque walls, moraines and flat valley floors are in the data itself
• 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 cliffs 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 - the demo scenes are made for native 4K in all three pipelines, pixel error 3 on every terrain

​

✦ 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 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 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.
