35 mountain maps from Iceland in deep winter snow - ridges, cirques and stepped basalt walls, 400 km² per map

Knife-edge crests between snow-filled cirques, valley walls built of stacked lava flows, plateau escarpments cut by long glacial valleys. Made from real-world elevation data (DEM) at 2.46 m per pixel; up to 1,715 m of relief on a single map, each map 20 km on a side.

​

✦ WHAT YOU GET

• 35 heightmaps - 16-bit PNG at 8129 x 8129 px, from 676 m to 1,715 m of relief
• Exact Unity terrains - 2 x 2 tiles of 4097 samples per map with no resampling; one height level is 20.6 to 52.3 mm
• Sawtooth Ridges, Deep Valley Peaks, Basalt Gorge - the demo levels, each in Built-in, URP and HDRP
• Verify - compares every built terrain with the original pixels

​

✦ MOUNTAINS IN WINTER

• Stepped basalt walls - every map gets its own bed table: dark lava flows with thin reddish layers between them, snow on each ledge
• Drifts where the wind drops them - gullies, cirques and lee slopes fill deep; crests and spurs are scoured to crust and rock
• Talus at the foot of the cliffs - dark scree with snow between the stones
• Paint any of the 35 maps - the Iceland Winter Ground painter gives every map the look of the demo levels, with one-click restore
• Clean steep faces - side projection keeps the rock sharp on walls instead of stretched

​

✦ MEASURED AT NATIVE 4K

• RTX 3090, player builds - HDRP 60-115 FPS · URP 62-129 FPS · Built-in 102-251 FPS

​

✦ REQUIREMENTS

Unity 2022.3 and above, with Built-in, URP and HDRP content in one package. The Project Setup window enables terrain holes in your pipeline asset. The Built-in demo levels have no post-processing and look simpler than URP and HDRP.

​

✦ GOOD FOR

Mountaineering and survival games, ski and snowmobile games, hiking and flight simulators, winter film backdrops.
