Procedural Islands 8K & 4K - 62 Terrains

62 procedural terrains for Unity - mountain islands in the sea, calderas, fjords and inland lakes. 29 large 8K maps of about 16 x 16 km and 33 4K maps of 8 x 8 km, all at exact 1:1 scale, with a realistic ground look: dark grey rock, snow on the high tops, alpine meadows and real water.
WHAT YOU GET
29 8K heightmaps - 16-bit PNG, about 8097 x 8097 pixels, 16.2 km per side
33 4K heightmaps - 16-bit PNG, 4001 x 4001 pixels, 8.0 km per side
Natural heights - 2 m between samples, each map's height range set for its relief (281 to 780 m)
9 demo scenes - 3 levels in Built-in, URP and HDRP, each with its own low side sun

ONE-CLICK TERRAIN BUILDER
Any map, finished - ground textures, snow, lakes, sea and shoreline foam in one click
Snow line control - snow on the high ground, lower on north-facing slopes, bare rock on steep faces
Lakes - basins fill automatically to the depth you choose; islands get a sea to the horizon
Exact pixels - no resampling: every terrain sample is an original heightmap pixel

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

PERFORMANCE
Native 4K - Built-in 327-389 FPS, URP 199-229 FPS, HDRP 81-150 FPS in the demo levels
Setup window - one button for the few project settings a package cannot carry
