45 procedural canyon terrains, 8.128 x 8.128 km each (about 8 x 8 km) at 1 m resolution, exact 1:1 scale in Unity. Grassland and Red Rock looks, 18 demo scenes for Built-in, URP and HDRP.Unity 2022.3 and above. Built-in, URP and HDRP in one package. Exact-scale terrains (1 unit = 1 m) built from the original heightmap pixels.▶ Full 4K video showcase: https://youtu.be/RLw1p9Swk1g▶ Red Rock look (no grass) video: https://youtu.be/c9oGitQAJag45 procedural canyon landscapes at their exact size - in two ground looksEvery 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 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. Tools > Procedural Terrains > Project Setup switches on terrain holes in your pipeline asset with one click.✦ USE CASESOpen-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.• 45 heightmaps, 16-bit greyscale PNG, 8129 x 8129 px, 1 m sample spacing, 8.128 x 8.128 km (about 8 x 8 km, 64 square km) each• Height range 348.2 m to 471.0 m (lowest point of each map at 0)• Unity terrains: 2 x 2 tiles of 4097 samples per map, terrain holes for the exact edge• 6 demo map prefabs (3 maps x 2 ground looks; one prefab works in every pipeline) + 18 demo scenes (6 per pipeline)• 14 terrain layers with 4096 x 4096 albedo, normal and mask textures (Grassland, Red Rock and Sand looks)• Anti-tiling, world-aligned terrain shaders for Built-in, URP and HDRP• Editor tools: Terrain Builder, Project Setup; PDF documentation included• Unity 2022.3 and above; Built-in, URP and HDRP
