41 maps of Siberia's high ranges in midwinter, with up to 1,638 m of relief on one map
Sharp ridges, deep couloirs, rock walls and the talus below them - the steepest ground of the series. The maps come from real-world elevation data (DEM) of Siberia in Russia and keep every original pixel: 8129 x 8129 px at 2 m, 16,256 m per side, 264 km².
✦ ROCK AND SNOW, RESOLVED PER PIXEL
On a wall, snow and rock meet in a thousand small places. The material decides between them pixel by pixel, in all three render pipelines:
- Ledges - snow lines follow the beds of the rock across a whole face
- Ribs and couloirs - rock stands out on the ribs, snow fills the couloirs between them
- Two rocks - dark bedded rock and pale grey granite, mixed by the Pale Rock setting
- Talus - block fields under every wall, their gaps filled with snow
✦ ABOVE THE TREE LINE
- Wind slab - hard wind-packed snow with a satin sheen on the open slopes
- Sastrugi - wind-carved ridges, drawn in world space along the wind, with no visible repeat
- Scoured ridges - thin snow with grass tips and stone tops on crests and windward slopes
- Sheltered hollows - soft matte powder in the lee and on the valley floors
✦ FILES AND TERRAINS
- 41 heightmaps - 16-bit greyscale PNG; relief from 865 m to 1,638 m
- True scale - 2 x 2 Unity terrains of 4097 samples per map, 8,192 m per tile, edge samples shared
- Honest precision - Unity stores terrain heights in 32,767 levels: 26.4 to 50.0 mm per level on these maps
- Demo - 3 maps as 9 scenes (Built-in, URP, HDRP): Curved Range, High Peaks and Long Mountain Valley
- Layers - eight winter ground layers at 4096 px
✦ TOOLS
- Terrain Builder - any of the 41 heightmaps becomes a set of terrains in one click (full / half / quarter detail)
- Siberia Winter Ground - paints selected terrains from their own shape: wind, crests and hollows, slope, sun side, roughness, drainage, tree line
- Four presets - High Ranges, Mountain Valleys, Uplands and Plateaus, Lakes and River Plains
- Build and Paint - heightmap PNG in, painted map out
- Restore Terrains Before The Last Paint - disk-backed, works at any size; Ctrl+Z on small terrains
- Not only these maps - the painter works on any Unity terrain
✦ 4K PERFORMANCE
