28 real-world LIDAR terrains from 7 US states, 8.128 x 8.128 km each at 1 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/qlEBsmkByfQAppalachian plateaus, northern mountains and southern lowlands of the eastern USA at their real size28 real-world terrains from LIDAR elevation data (Kentucky 8, New Hampshire 3, New York 4, Georgia 5, Mississippi 5, Tennessee 2, Virginia 1). The deeply cut plateau of eastern Kentucky, the mountains of New Hampshire, the hills and valleys of New York, the ridge-and-valley country of Tennessee and the lowlands of Georgia, Mississippi and Virginia. Every heightmap covers 8.128 x 8.128 km (about 8 x 8 km, 64 square km) with 1 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 INSIDE28 heightmaps - 16-bit PNG, 8129 x 8129 px, one folder per state, height range from 30.7 m to 793.6 m3 demo levels x 3 render pipelines - 9 ready scenes to fly or walk through: Mountain Notch, Coal Plateau, Ridge and ValleyTerrain Builder - one click turns any heightmap into seamless real-scale Unity terrainsUSA II ground look - 6 ground layers in 4K made for US mountains, deserts, plains and hills (meadow, forest floor, dry earth, scree, rock, gravel), painted automatically from slope and landform✦ 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 patternsSeamless 2 x 2 tiles - each map is split into four 4097-sample terrains (Unity's limit) that share their edge pixelsLake water - taken from the flat lake surface in the elevation data (Coal Plateau demo level)Verify - compares every terrain height with the original pixels✦ PERFORMANCENative 3840 x 2160 - no upscaling, demo scenes in player builds: Built-in 150-1122 FPS · URP 191-275 FPS · HDRP 152-180 FPS (RTX 3090)✦ 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.
