47 real-world LIDAR terrains of Scotland, 4.958 x 4.958 km each at 0.61 m resolution, true 1:1 scale in Unity. 9 demo scenes, Built-in/URP/HDRP.Unity 2022.3 and above. Built-in, URP and HDRP in one package. Real-scale terrains (1 unit = 1 m) built from the exact heightmap pixels.Coastal inlets, escarpments, hills and lochans of Scotland at their real size47 real-world terrains from LIDAR elevation data. Rugged coast, sea inlets, escarpments, moorland hills and lochs of Scotland. Every heightmap covers 4.958 x 4.958 km (about 5 x 5 km, 25 square km) with 0.61 m between samples. Every Unity terrain sample is an original heightmap pixel - nothing is stretched or resampled - and 1 Unity unit is 1 metre.✦ GOOD TO KNOWThe Scotland collection has 93 maps in two packs. Part 1 (this pack) holds maps 1-47 (47 maps); Part 2 holds maps 48-93 (46 maps). Both parts are the same collection of Scotland - no map is in both parts, and each pack works on its own.✦ WHAT'S INSIDE47 heightmaps - 16-bit PNG, 8129 x 8129 px, height range from 56.3 m to 496.6 m3 demo levels x 3 render pipelines - 9 ready scenes to fly or walk through: Coastal Inlet, Escarpment, Hills & LochansTerrain Builder - one click turns any heightmap into seamless real-scale Unity terrainsScotland moorland ground look - 7 ground layers in 4K (meadow, forest floor, dry earth, scree, rock, gravel, lake bed), painted automatically from slope, landform and heightWater - sea and lochs: mirror lochs that reflect the surrounding hills, with gently moving ripples and deeper water towards the middle; the sea stays an ocean with a rolling swell, in Built-in, URP and HDRP✦ FEATURESExact scale - size and height range are in every file name and inside every PNG, and the builder reads them for youAnti-tiling terrain shaders - every layer blends three texture sizes by viewing distance, so no repeating patternsCliffs without stretching - textures are projected from the side on steep faces, so cliffs show real rock texture instead of vertical streaks; flat ground is unchangedSeamless 2 x 2 tiles - each map is split into 4 terrains of 4097 samples (Unity's limit) that share their edge pixelsVerify - compares every terrain height with the original pixels✦ PERFORMANCENative 3840 x 2160 - no upscaling, demo scenes in player builds: Built-in 240-318 FPS · URP 120-142 FPS · HDRP 143-174 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.
