Prairie hills, sandhills, river bluffs and farmland of the American heartland at their real size

28 real-world terrains from LIDAR elevation data (Nebraska 6, Kansas 3, Oklahoma 4, Iowa 4, Illinois 4, Indiana 4, Ohio 1, Wisconsin 2). The grass-covered dunes of the Nebraska Sandhills, prairie from Kansas and Oklahoma, branching valleys from Iowa, river bluffs from Illinois and the rolling farmland of Indiana, Ohio and Wisconsin. 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 INSIDE

• 28 heightmaps - 16-bit PNG, 8129 x 8129 px, one folder per state, height range from 25.6 m to 122.9 m
• 3 demo levels x 3 render pipelines - 9 ready scenes to fly or walk through: Sandhills, Dissected Hills, River Bluffs
• Terrain Builder - one click turns any heightmap into seamless real-scale Unity terrains
• USA 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

✦ 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
• Seamless 2 x 2 tiles - each map is split into four 4097-sample terrains (Unity's limit) that share their edge pixels
• Verify - compares every terrain height with the original pixels

✦ PERFORMANCE

• Native 3840 x 2160 - no upscaling, demo scenes in player builds: Built-in 384-429 FPS · URP 134-804 FPS · HDRP 115-191 FPS (RTX 3090)

✦ 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.

✦ 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.
