England Levels, Heaths & Weald Real-World Terrains 16 km²

• Heightmaps - 40 x 16-bit greyscale PNG, 4033 x 4033 px: 40 maps of 4.03 x 4.03 km (about 4 x 4 km, 16 square km) at 1 m per pixel
• Relief - 15 m to 241 m per map (lowest point of each map at 0)
• Unity terrains - one terrain of 4097 samples per map, terrain holes for the exact edge
• Height precision - one height level is about 0.5 mm on the flattest map and about 7.3 mm on the map with the largest height range
• Demo content - 3 map prefabs (one prefab works in every pipeline) + 9 demo scenes (3 per pipeline)
• Ground textures - Wetland and Heath (8 ground layers) + the shared ground layers, 4096 x 4096 albedo with smoothness, normal and mask
• Rock beds - a bed table per demo map, read by the terrain shader in Built-in, URP and HDRP
• Water - Shore Water: transparent lake surfaces, only on level water of the demo maps (lakes only, no rivers), coloured by the real water depth (depth texture), for Built-in, URP and HDRP
• Shaders - anti-tiling, world-aligned terrain shaders (hex-tile stochastic sampling, three texture sizes blended by viewing distance, ground variation at four sizes) with side projection on steep faces, rock beds and plane-mapped fine relief, for Built-in, URP and HDRP
• Editor tools - Terrain Builder, Project Setup, Shore Water Setup, England Ground Textures; PDF documentation included
• Compatibility - Unity 2022.3 and above; Built-in, URP and HDRP

Levels, heaths and Weald country of southern England - flat wetland levels, pitted heathland, limestone gorges and ghyll valleys at their real size, 4 x 4 km per map at 1 m

40 maps of the levels, heaths and Weald country of Somerset, Devon, Dorset, Hampshire and Sussex, made from real-world elevation data (LiDAR DTM, 1 m). Flat drained levels cut by ditches and rivers, islands of higher ground, sandy heathland with old pits, limestone gorges and quarry faces, and the small fields and steep stream valleys of the Weald - with up to 241 m of relief on a single map. Each map covers 4.03 x 4.03 km (about 4 x 4 km, 16 square km) at 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.

​

✦ WHAT'S INSIDE

• 40 heightmaps - 16-bit PNG, 4033 x 4033 px, relief from 15 m to 241 m per map
• One Unity terrain per map - one terrain of 4097 samples per map; the unused 64-sample edge strip is cut away with terrain holes, lowest point at Y = 0
• 3 demo levels x 3 render pipelines - 9 ready scenes to fly or walk through: Levels River, Limestone Gorge, Heath Pits
• Terrain Builder - one click turns any heightmap into a real-scale Unity terrain
• Wetland and Heath ground look - 8 ground layers in 4K: meadow, woodland ground, mud, limestone scree, limestone, sand, reeds, heathland
• Late summer on the levels and heaths - the ground of the demo levels is painted from the real shape of each map at 1 m: meadow on the flat levels, reeds along the ditches and in the mires, mud on the river banks, heathland and sand on the heaths and in the old pits, limestone and scree in the gorges and quarries, and woodland ground in the steep stream valleys of the Weald

​

✦ LEVELS AND HEATH GROUND

• No visible tiles or seams - every layer is read with hex-tile stochastic sampling at three sizes, aligned to the world and blended by viewing distance, with ground variation at four sizes on top - no repeating pattern up close, in the middle distance or from the air, and no seams between terrains
• Rock beds where the rock is bedded - each demo map has its own bed table that the terrain shader reads: limestone gorge and quarry faces show beds and ledges, the sandstone of the heaths and the Weald keeps its own colour
• Painted from the real shape at 1 m - flat ground and the map's own drainage find the levels, ditches and mires, local relief finds the heath pits, slope finds the gorge faces and steep stream valleys, and the 1 m data finds the field parcels and their boundaries
• Fine surface relief - lumps and hollows finer than the height data on the near ground, plane-mapped so they never stretch down steep faces, fading out with distance

​

✦ FEATURES

• Real-world maps at 1 m - 4 x 4 km (16 km²) of real ground per map, at 1 m between samples: flat levels, drainage ditches, heath pits, limestone gorges, vales and ghyll valleys are in the data itself
• Exact scale - size and height range are in every file name and inside every PNG, and the builder reads them for you
• Steep faces without stretching - textures are projected from the side on steep faces, so tors, scarps and quarry walls show real rock texture instead of vertical streaks; flat ground is unchanged
• Verify - compares every terrain height with the original pixels

​

✦ PERFORMANCE

• Native 3840 x 2160 - no upscaling, demo scenes in player builds: HDRP 90-144 FPS · URP 66-110 FPS · Built-in 114-185 FPS (RTX 3090)

​

✦ DEMO CONTROLS

Mouse 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 ABOVE

Built-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 CASES

Open-world games · walking, flight and driving simulators · survival, exploration and countryside games · cinematics · terrain studies. The heightmaps also work in other tools: 16-bit PNG, north up, size and height range in the file name.
