British Columbia Lakes & Rivers Real-World Terrains 16 km²

• Heightmaps - 32 x 16-bit greyscale PNG, 4033 x 4033 px: 32 maps of 4.032 x 4.032 km (about 4 x 4 km, 16 square km) at 1 m per pixel
• Relief - 56 m to 1,367 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 0.2 cm on the flattest map and about 4.2 cm 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 - 8 British Columbia Lakes and Rivers ground layers + the shared ground layers, 4096 x 4096 albedo, normal and mask
• Water - 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 HDRP
• Shaders - anti-tiling, world-aligned terrain shaders with side projection on steep faces (triplanar) for Built-in, URP and HDRP
• Editor tools - Terrain Builder, Project Setup, British Columbia Ground Textures; PDF documentation included
• Compatibility - Unity 2022.3 and above; Built-in, URP and HDRP

The long valley lakes and great meandering rivers of British Columbia, Canada - steep lakeshores, river deltas, oxbow lakes, cut banks and gravel bars - at their real size, at 1 m resolution

32 heightmaps of the lakes and rivers of British Columbia, Canada from real-world elevation data (DEM). Long, deep valley lakes under forested mountainsides, river deltas, a great meandering river with oxbow lakes, scroll bars and high cut banks, and lake-dotted wetlands of British Columbia. Each map covers 4.032 x 4.032 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

• 32 heightmaps - 16-bit PNG, 4033 x 4033 px, relief from 56 m to 1,367 m per map
• One Unity terrain per map - 4097 samples at the map's own 1 m spacing; the unused 64-sample strip at the edge is cut away with terrain holes
• 3 demo levels x 3 render pipelines - 9 ready scenes to fly or walk through: River Meanders, Mountain Lakeshore, Long Lake
• Terrain Builder - one click turns any heightmap into a real-scale Unity terrain
• British Columbia Lakes and Rivers ground look - 8 ground layers in 4K (meadow, forest floor, dry earth, scree, rock, gravel, bog, lake bed)
• Shore water - transparent long valley lakes, a great meandering river with oxbow lakes, wetland lakes 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 HDRP
• Floodplains, cut banks and shores - the ground of the demo levels is painted from the real shape of each map: forest floor on the slopes, riverside meadows and wet hollows on the floodplains, pale silt on the cut banks, sand and gravel along the water, bare rock only on real walls

​

✦ FEATURES

• Exact scale - size and height range are in every file name and inside every PNG, and the builder reads them for you
• 1 m resolution - cut banks, scroll bars, oxbow lakes, deltas, gravel bars and shorelines are in the data itself
• Anti-tiling terrain shaders - every layer blends three texture sizes by viewing distance, so no repeating patterns
• Cliffs without stretching - textures are projected from the side on steep faces, so 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 - the demo scenes are made for native 4K in all three pipelines, pixel error 3 on every terrain

​

✦ 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 · 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.
