​Siberia's taiga uplands and plateaus under deep snow: 36 true-scale maps for Unity, each one 16,256 m across

Rounded uplands, flat table lands and the scarps that drop from them, taken from real-world elevation data (DEM) of Siberia, Russia, at 2 m per pixel. The relief runs from 343 m on the gentlest map to 906 m on the boldest, and every map covers 264 km².

​

✦ WHAT WINTER DOES TO A PLATEAU

• Below the tree line - soft, dry powder lies deep and sheltered, without a single wind form
• On the open tops - the wind packs the snow hard and carves sastrugi, long ridges that run with the wind
• Along the scarps - dark bedded rock breaks through in steps, each ledge of its beds holding a line of snow
• Under the cliffs - block fields half buried in snow, only their stone tops showing

​

✦ THE NUMBERS

• Heightmaps - 36 files, 16-bit greyscale PNG, 8129 x 8129 px
• Scale - 1 pixel = 2 m = 1 terrain sample; no map is ever resampled
• Terrains - 2 x 2 per map, 4097 samples and 8,192 m per tile, seamless across the shared edges
• Heights - lowest point at 0; Unity keeps 32,767 height levels, 10.5 to 27.7 mm each on these maps
• Demo scenes - 9: Stepped Table Land, Range Front and River Plain and Ridges and River Valley in Built-in, URP and HDRP
• Ground layers - eight, in 4K: soft powder, thin scoured snow, wind slab, dark rock, pale granite, block field, clear ice and white ice

​

✦ PAINT THE OTHER 33 MAPS - OR YOUR OWN TERRAIN

The Terrain Builder turns any heightmap of the pack into terrains with one click (full, half or quarter detail). The Siberia Winter Ground window then paints them like the demo scenes. It needs no masks: it measures shelter and exposure for the wind direction you set, crests and hollows at several sizes, slope, sun side, roughness and drainage.

• Presets - Uplands and Plateaus is made for these maps; Lakes and River Plains, Mountain Valleys and High Ranges come with it
• Tree Line - one slider moves the border between sheltered powder and wind-worked snow
• Kurum, Rock Amount, Beds - more or fewer block fields, more or less bare rock, rock beds on or off
• Build and Paint - from a heightmap PNG to a painted map in one step
• Restore - the ground before the last paint is kept on disk and comes back with one button

​

✦ MATERIAL

One winter terrain material for all three render pipelines. Hex-tile stochastic sampling and several distance scales stop texture repeats, four scales of ground variation break up the white, steep faces are projected from the side, and on rock the snow is resolved against the stone per pixel, so ledges and ribs stay crisp. Powder is matte, wind slab has a satin sheen.

​

✦ FRAME RATE

Demo scenes in player builds, native 3840 x 2160 with no upscaling, RTX 3090: HDRP 149-158 FPS · URP 172-182 FPS · Built-in 291-353 FPS.

​

• Ground only - terrains, ground layers and tools; no plant or object meshes and no water surfaces
• Demo light - a low sun, 13 degrees up in the south, and long blue shadows
