Iceland Mountains & Valleys Real-World Terrains 8 km

▶ Full 4K video showcase: https://youtu.be/PlDn3nLJ6rw

The gullied basalt mountains, cirques, snowfields and trough valleys of Iceland at their real size, at 2 m resolution

73 heightmaps of Iceland from real-world elevation data (DEM). Layered basalt mountains with deep gullies, cirques and plateau snowfields above green trough valleys and mountain lakes of Iceland. 72 maps cover 8.06 x 8.06 km (about 8 x 8 km, 65 square km) at 2 m between samples; 1 map covers 8.95 x 8.95 km (about 9 x 9 km, 80 square km) at 2.22 m. Every Unity terrain sample is an original heightmap pixel - nothing is stretched or resampled - and 1 Unity unit is 1 metre.

​

✦ WHAT'S INSIDE

• 73 heightmaps - 16-bit PNG, 4033 x 4033 px, relief from 660 m to 1,510 m per map
• One Unity terrain per map - 4097 samples at the map's own 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: Snowy Cirques, High Ridges, Mountain Lake Valley
• Terrain Builder - one click turns any heightmap into a real-scale Unity terrain
• Iceland ground look - 8 ground layers in 4K (meadow, forest floor, dry earth, scree, rock, gravel, snow, ice)
• Water - lakes with natural waves travelling across the surface, soft shorelines and deeper water towards the middle, in Built-in, URP and HDRP
• Snowfields - on the highest tops and plateaus in the demo levels

​

✦ FEATURES

• Exact scale - size and height range are in every file name and inside every PNG, and the builder reads them for you
• 2 m resolution - gullies, moraines, lava edges and canyon walls 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 cliffs 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 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 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.
