The glaciated peaks of British Columbia, Canada - sharp ridges, cirques, talus slopes, alpine lakes and deep U-shaped valleys - at their real size, at 1 m resolution
38 heightmaps of the high mountains of British Columbia, Canada from real-world elevation data (DEM). Sharp ridges and summits, glacier-carved cirques, avalanche gullies, talus slopes, alpine lakes and deep U-shaped valleys of British Columbia's high mountains, with up to 1,787 m of relief on a single map. 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
- 38 heightmaps - 16-bit PNG, 4033 x 4033 px, relief from 1,060 m to 1,787 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: Alpine Ridges, Glacial Valley, Alpine Lake
- Terrain Builder - one click turns any heightmap into a real-scale Unity terrain
- British Columbia Alpine Peaks ground look - 8 ground layers in 4K (meadow, forest floor, dry earth, scree, rock, gravel, snow, lake bed)
- Shore water - transparent cirque tarns, alpine lakes and mountain 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
- Tree line, talus and snow - the ground of the demo levels is painted from the real shape of each map: forest floor below a tree line that follows the relief, alpine meadow and heather above it, bare rock on real walls and crests, talus below them, green avalanche paths and summer snow only in high, shaded hollows
✦ 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 - aretes, cirque headwalls, avalanche gullies, talus cones, moraines and stream channels 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.
