USA Mountains & Southwest Real-World Terrains 8K

Rocky Mountain peaks, mountain lakes, canyons and southwestern mesas at their real size.

50 real-world terrains from LIDAR elevation data (Colorado 7, Idaho 5, Montana 4, Wyoming 8, Utah 9, Arizona 4, New Mexico 7, Texas 6). Rugged peaks from Colorado, mountain ridges and a large lake from Idaho, high plains and ridges from Montana and Wyoming, canyon and mountain country from Utah, and the mesas, canyons and high desert of Arizona, New Mexico and Texas. 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
- 50 heightmaps - 16-bit PNG, 8129 x 8129 px, one folder per state, height range from 30.7 m to 1397.7 m
- 3 demo levels x 3 render pipelines - 9 ready scenes to fly or walk through: Rugged Peaks, Mountain Lake, Mesa Country
- 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
- Lake water - taken from the flat lake surface in the elevation data (Mountain Lake demo level)
- Verify - compares every terrain height with the original pixels

PERFORMANCE
- Native 3840 x 2160 - no upscaling, demo scenes in player builds: Built-in 198-532 FPS · URP 138-292 FPS · HDRP 130-216 FPS (RTX 3090)

DEMO CONTROLS

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.
