Procedural Mountains & Rivers 8K - 37 Terrains

37 procedural terrains for Unity - snow peaks, rocky highlands and river gorges. Every map is about 16 x 16 km at exact 1:1 scale, with a realistic ground look: grey rock, snow on the mountain tops, alpine meadows and real water.

WHAT YOU GET
37 heightmaps - 16-bit PNG, 8097 x 8097 pixels, 2 m between samples, about 16.3 km per side
Natural heights - each map's height range set for its relief type (391 to 710 m)
3 relief folders - Mountains (13), River (10), Rocky Landscape (14)
9 demo scenes - 3 levels in Built-in, URP and HDRP, each with its own hand-tuned lighting


ONE-CLICK TERRAIN BUILDER
Any map, finished - ground textures, snow, lakes and shoreline foam in one click
Snow line control - lower on north-facing slopes, bare rock on steep faces
Lakes - basins fill automatically to the depth you choose
Exact pixels - no resampling: every terrain sample is an original heightmap pixel (2 x 2 Unity terrains per map)


REALISTIC LOOK
8 ground layers at 4K - meadow, pasture, forest floor, stony earth, scree, grey rock, snow, lake bed
No visible tiling - re-assembled textures plus anti-tiling terrain shaders
Realistic water - HDRP water surfaces with reflections and shoreline foam; own lake and sea shader for Built-in and URP
