Procedural Canyon Terrains 8K

45 procedural canyon landscapes at their exact size - in two ground looks

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. Use the canyons green with grass, or as red rock canyons with banded sandstone walls and no grass.

✦ WHAT'S INSIDE

• 45 heightmaps - 16-bit PNG, 8129 x 8129 px, height range from 348.2 m to 471.0 m

• 18 demo scenes - 6 demo levels x 3 render pipelines: Canyon Network, Mesa Plateaus and Terraced Benches, each in the Grassland and the Red Rock look

• Terrain Builder - one click turns any heightmap into seamless exact-scale Unity terrains

• 14 ground layers in 4K - painted automatically from slope and landform in three looks: Grassland (meadow, forest floor, dry earth, scree, rock, gravel), Red Rock (banded sandstone walls, talus, red sand, hardpan, gravel - no grass) and wind-rippled Sand

✦ 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 94-164 FPS · URP 69-146 FPS · HDRP 99-139 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 > Procedural Terrains > Project Setup switches on terrain holes in your pipeline asset with one click.

✦ USE CASES

Open-world games · flight and driving simulators · survival games · cinematics · level prototyping. The heightmaps also work in other tools: 16-bit PNG, north up, size and height range in the file name.
