Italy Apennines & Volcanoes Real-World Terrains 20 km

• Heightmaps - 97 x 16-bit greyscale PNG, 2017 x 2017 px: 97 maps of 20.16 x 20.16 km (about 20 x 20 km, 406 square km) at 10 m per pixel
• Relief - 164 m to 3,164 m per map (lowest point of each map at 0)
• Unity terrains - one terrain of 2049 samples per map, terrain holes for the exact edge
• Height precision - one height level is about 0.5 cm on the flattest map and about 9.7 cm on the map with the largest height range
• Demo content - 3 map prefabs (one prefab works in every pipeline) + 9 demo scenes (3 per pipeline)
• Ground textures - 8 Italian ground layers + the shared ground layers, 4096 x 4096 albedo, normal and mask
• Water - lake surfaces with travelling waves, soft shorelines and depth shading for Built-in, URP and HDRP
• Shaders - anti-tiling, world-aligned terrain shaders with side projection on steep faces (triplanar) for Built-in, URP and HDRP
• Editor tools - Terrain Builder, Project Setup, Italy Ground Textures; PDF documentation included
• Compatibility - Unity 2022.3 and above; Built-in, URP and HDRP

Etna, mountain lakes and Apennine ridges of Italy at their real size, at 10 m resolution

97 heightmaps of Italy from real-world elevation data. Etna, crater lakes, Apennine ridges, hills and volcanic cones of Italy, with snow on the highest tops. Each map covers 20.16 x 20.16 km (about 20 x 20 km, 406 square km) with 10 m between samples. Every Unity terrain sample is an original heightmap pixel - nothing is stretched or resampled (the demo levels only soften a narrow band along low lake shores) - and 1 Unity unit is 1 metre.

✦ WHAT'S INSIDE

• 97 heightmaps - 16-bit PNG, 2017 x 2017 px, relief from 164 m to 3,164 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: Etna, Mountain Lake, Apennine Ridge
• Terrain Builder - one click turns any heightmap into a real-scale Unity terrain
• Italian ground look - 8 ground layers in 4K (meadow, forest floor, dry earth, scree, rock, gravel, snow, lake bed), painted automatically from slope, landform and height
• Water - lakes with natural waves travelling across the surface, soft shorelines and deeper, darker water towards the middle, in Built-in, URP and HDRP
• Snow - on the highest tops

✦ FEATURES

• 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 cliffs show real rock texture instead of vertical streaks; flat ground is unchanged
• Verify - compares every terrain height with the original pixels

✦ 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.
