21 real-world heightmaps of Kings and Saint John, New Brunswick, Canada, about 10 x 10 km each at 1.23 m, true 1:1 scale. 9 demo scenes, Built-in/URP/HDRP.Unity 2022.3 and above. Built-in, URP and HDRP in one package.▶ Full 4K video showcase: https://youtu.be/u3q4axM0XTcThe rugged hills, lake chains, highland ponds and farm valleys of Kings and Saint John counties in southern New Brunswick, Canada, at their real size, at 1.23 m resolution21 heightmaps of Kings and Saint John counties in southern New Brunswick, Canada from real-world elevation data (DEM). Rugged hills and ridges, chains of lakes in long valleys, ponds on the uplands and farm valleys of southern New Brunswick. Each map covers 9.997 x 9.997 km (about 10 x 10 km, 100 square km) at 1.23 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 INSIDE21 heightmaps - 16-bit PNG, 8129 x 8129 px, relief from 138 m to 374 m per map2 x 2 Unity terrains per map - 4097 samples each at the map's own 1.23 m spacing (one heightmap cut into 4 tiles that share their edge pixels); the unused 64-sample strip at the edge is cut away with terrain holes3 demo levels x 3 render pipelines - 9 ready scenes to fly or walk through: Lake Chain, Rugged Hills, Highland PondsTerrain Builder - one click turns any heightmap into a real-scale Unity terrainNew Brunswick Lowlands ground look - 8 ground layers in 4K (meadow, forest floor, dry earth, scree, rock, gravel, bog, lake bed)Shore water - transparent lake chains, highland ponds and streams: clear at the shoreline, the bed visible in the shallows, darker water further out, rivers that follow the valley downhill, a thin moving shore film and wet ground just above the water, in Built-in, URP and HDRPForest floor, fields and bogs - the ground of the demo levels is painted from the real shape of each map: forest floor on the slopes, fields on the valley floors, bare rock only on real walls, bogs on the wet flats✦ FEATURESExact scale - size and height range are in every file name and inside every PNG, and the builder reads them for you1.23 m resolution - river bluffs, terraces, gullies, stream channels, field edges and shorelines are in the data itselfAnti-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 walls show real rock texture instead of vertical streaks; flat ground is unchangedVerify - compares every terrain height with the original pixels✦ PERFORMANCENative 3840 x 2160 - no upscaling, demo scenes in player builds: HDRP 146-186 FPS · URP 132-194 FPS · Built-in 204-430 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 > Lidar Terrains > Project Setup switches on terrain holes, and Shore Water Setup the depth and opaque textures the water reads, in your pipeline asset with one click. The Built-in Render Pipeline has no post-processing, so the Built-in demo levels look simpler than the URP and HDRP ones.✦ USE CASESOpen-world games · flight and driving simulators · hiking, fishing 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.Heightmaps - 21 x 16-bit greyscale PNG, 8129 x 8129 px: 21 maps of 9.997 x 9.997 km (about 10 x 10 km, 100 square km) at 1.23 m per pixelRelief - 138 m to 374 m per map (lowest point of each map at 0)Unity terrains - 2 x 2 terrains of 4097 samples per map, terrain holes for the exact edgeHeight precision - one height level is about 0.4 cm on the flattest map and about 1.1 cm on the map with the largest height rangeDemo content - 3 map prefabs of 2 x 2 terrains (one prefab works in every pipeline) + 9 demo scenes (3 per pipeline)Ground textures - 8 New Brunswick Lowlands ground layers + the shared ground layers, 4096 x 4096 albedo, normal and maskWater - transparent lake and river surfaces whose colour comes from the real water depth (depth texture), soft shorelines, travelling waves and river flow, for Built-in, URP and HDRPShaders - anti-tiling, world-aligned terrain shaders with side projection on steep faces (triplanar) for Built-in, URP and HDRPEditor tools - Terrain Builder, Project Setup, New Brunswick Ground Textures; PDF documentation includedCompatibility - Unity 2022.3 and above; Built-in, URP and HDRP
