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

✦ PERFORMANCE

• Native 4K - Built-in 68-368 FPS, URP 146-235 FPS, HDRP 107-138 FPS in the demo levels
• Setup window - one button for the few project settings a package cannot carry
