80 real-world heightmaps of Finland, about 6 x 6 km each at 2.97 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.The lakes, eskers, bogs and glacier-polished granite hills of Finland at their real size, at 2.97 m resolution80 heightmaps of Finland from real-world elevation data (DEM). Lake mazes with rocky islands, long esker ridges, open bogs, drumlin fields and low granite hills of the Finnish lakeland. Each map covers 5.988 x 5.988 km (about 6 x 6 km, 36 square km) at 2.97 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 INSIDE80 heightmaps - 16-bit PNG, 2017 x 2017 px, relief from 20 m to 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: Lake Maze, Esker Islands, Bog Plain and StreamsTerrain Builder - one click turns any heightmap into a real-scale Unity terrainFinland ground look - 8 ground layers in 4K (meadow, forest floor, dry earth, scree, rock, gravel, bog, lake bed)Water - lakes with natural waves travelling across the surface, soft shorelines and deeper water towards the middle, in Built-in, URP and HDRPBogs - open sphagnum mire painted on the smooth, wet flats of the data in the demo levels✦ FEATURESExact scale - size and height range are in every file name and inside every PNG, and the builder reads them for you2.97 m resolution - esker ridges, drumlins, rocky knobs, shorelines and stream channels are in the data itselfAnti-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✦ PERFORMANCENative 3840 x 2160 - the demo scenes are made for native 4K in all three pipelines, pixel error 3 on every terrain✦ 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.
