45 real-world heightmaps of Gloucester and Kent, 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. Real-scale terrains (1 unit = 1 m) built from the exact heightmap pixels.▶ Full 4K video showcase: https://youtu.be/kGcoiguTEDcThe gentle Acadian plain of Gloucester and Kent counties in north-eastern New Brunswick, Canada - winding rivers in steep ravines, wide raised bogs and rolling wooded hills - at their real size, at 1.23 m resolution45 heightmaps of Gloucester and Kent counties in north-eastern New Brunswick, Canada from real-world elevation data (DEM). The low Acadian plain of north-eastern New Brunswick: winding rivers in steep sandstone ravines, wide raised peat bogs with pools and gently rolling wooded hills. 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 INSIDE45 heightmaps - 16-bit PNG, 8129 x 8129 px, relief from 51 m to 220 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: Meandering Ravine, Bog Lake, Valley RidgesTerrain Builder - one click turns any heightmap into a real-scale Unity terrainNew Brunswick Acadian Plain ground look - 8 ground layers in 4K (meadow, forest floor, dry earth, scree, rock, gravel, bog, lake bed)Shore water - transparent winding rivers, bog pools and ponds: 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 150-169 FPS · URP 144-155 FPS · Built-in 283-352 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.✦ MORE NEW BRUNSWICK TERRAINSSame format, same tools, neighbouring counties:New Brunswick Restigouche Highlands - https://assetstore.unity.com/packages/slug/424572New Brunswick Madawaska River Valleys - https://assetstore.unity.com/packages/slug/424574New Brunswick Kings & Saint John Hills - https://assetstore.unity.com/packages/slug/424582Heightmaps - 45 x 16-bit greyscale PNG, 8129 x 8129 px: 45 maps of 9.997 x 9.997 km (about 10 x 10 km, 100 square km) at 1.23 m per pixelRelief - 51 m to 220 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 0.2 cm on the flattest map and about 0.7 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 Acadian Plain 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
