97 real-world heightmaps of Italy, 20.16 x 20.16 km each at 10 m resolution, true 1:1 scale in Unity. 9 demo scenes, Built-in/URP/HDRP.Unity 2022.3 and above. Built-in, URP and HDRP in one package. Real-scale terrains (1 unit = 1 m) built from the exact heightmap pixels.▶ Full 4K video showcase: https://youtu.be/qd2GcAKlGqgEtna, mountain lakes and Apennine ridges of Italy at their real size, at 10 m resolution97 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 INSIDE97 heightmaps - 16-bit PNG, 2017 x 2017 px, relief from 164 m to 3,164 m per mapOne 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 holes3 demo levels x 3 render pipelines - 9 ready scenes to fly or walk through: Etna, Mountain Lake, Apennine RidgeTerrain Builder - one click turns any heightmap into a real-scale Unity terrainItalian ground look - 8 ground layers in 4K (meadow, forest floor, dry earth, scree, rock, gravel, snow, lake bed), painted automatically from slope, landform and heightWater - lakes with natural waves travelling across the surface, soft shorelines and deeper, darker water towards the middle, in Built-in, URP and HDRPSnow - on the highest tops✦ FEATURESExact scale - size and height range are in every file name and inside every PNG, and the builder reads them for youAnti-tiling terrain shaders - every layer blends three texture sizes by viewing distance, so no repeating patternsCliffs without stretching - textures are projected from the side on steep faces, so cliffs show real rock texture instead of vertical streaks; flat ground is unchangedVerify - compares every terrain height with the original pixels✦ DEMO CONTROLSMouse 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 ABOVEBuilt-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 CASESOpen-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.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 pixelRelief - 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 edgeHeight 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 rangeDemo 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 maskWater - lake surfaces with travelling waves, soft shorelines and depth shading for Built-in, URP and HDRPShaders - anti-tiling, world-aligned terrain shaders with side projection on steep faces (triplanar) for Built-in, URP and HDRPEditor tools - Terrain Builder, Project Setup, Italy Ground Textures; PDF documentation includedCompatibility - Unity 2022.3 and above; Built-in, URP and HDRP
