Procedural Islands 8K & 4K – 62 Terrains

62 procedural heightmaps at exact 1:1 scale - 29 8K maps (16 km) and 33 4K maps (8 km): mountain islands in the sea, calderas, fjords and inland lakes. 9 demo scenes for Built-in, URP and HDRP.

• Heightmaps - 62 x 16-bit greyscale PNG: 29 8K (about 8097 px, 16192 m) + 33 4K (4001 px, 8000 m), 2 m spacing
• Height range - 281 to 780 m per map, lowest point at 0
• Terrains - 8K: 2 x 2 Unity terrains of 4097 samples (shared edges); 4K: one terrain of 4097; unused edge cut with terrain holes
• Precision - Unity's 32,767 height levels (at most half a level from the pixel)
• Ground layers - 8 terrain layers, 4096 x 4096 albedo / normal / mask
• Shaders - anti-tiling terrain shaders for Built-in, URP and HDRP; lake and sea water shader for Built-in and URP
• Water - HDRP water surfaces (lakes and ocean), shoreline foam ribbons
• Demo - 9 scenes (3 levels x Built-in / URP / HDRP), fly / walk camera
• Performance - native 3840 x 2160: Built-in 327+, URP 199+, HDRP 81+ FPS
• Tools - 8K & 4K Terrains Builder and Setup windows, documentation PDF
• Unity - 2022.3 and above

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

✦ ALSO IN THIS SERIES

• Procedural Ridged Mountains 8K & 4K - 54 Terrains
• Procedural Terraces 8K & 4K - 51 Terrains
• Shared tools - all packs share one Core and one tools folder, so several packs never duplicate them
