USA Great Plains & Midwest Real-World Terrains 8K

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)
