32 procedural island terrains, 8.128 x 8.128 km each (about 8 x 8 km) at 1 m resolution, exact 1:1 scale in Unity. 9 demo scenes with sea water 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/buuWo1M3RkE32 procedural islands and archipelagos at their exact size - up to 1059.8 m of reliefEvery 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. Rugged peak islands, twin ranges and low archipelagos, with sea water in the demo levels.✦ WHAT'S INSIDE• 32 heightmaps - 16-bit PNG, 8129 x 8129 px, height range from 163.8 m to 1059.8 m• 9 demo scenes - 3 demo levels x 3 render pipelines: Rugged Peak Island, Twin Ranges and Low Archipelago, with sea water at each map's coastline height• 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, used in the demos), Red Rock (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 222-473 FPS · URP 188-340 FPS · HDRP 88-105 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 and survival island games · flight and boat simulators · cinematics · level prototyping. The heightmaps also work in other tools: 16-bit PNG, north up, size and height range in the file name.• 32 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 163.8 m to 1059.8 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• 3 demo map prefabs with sea water (one prefab works in every pipeline) + 9 demo scenes (3 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
