Valheim 1.0 Seed Viewer & Map Generator
Generate and inspect procedural 10,000m radial world maps in your browser. This tool maps out continental biomes, boss sacrificial stones, trader locations, and the 1.0 Deep North glaciated polar boundary.
1.0 World Seed & Biome Map Viewer
Deterministic 10,000m radial procedural simulation. Fully client-side, zero latency, updated for Deep North 1.0.
How World Generation Works in Valheim 1.0
Every world in Valheim is a flat circular disk spanning 10,000 meters in radius (20,000 meters in total diameter) centered at coordinates (0, 0). When a player inputs an alphanumeric seed, the game hashes the string into a 32-bit integer seed value. This integer initializes multiple octaves of coherent Simplex and Perlin noise to calculate terrain elevation, humidity, temperature gradients, and vegetation distribution.
Radial Biome Bands
- Meadows (0m – 1,500m): Temperate starter center containing the Sacrificial Stones altar.
- Black Forest & Swamp (1,500m – 5,000m): Dense fir forests and coastal sunken lowlands.
- Mountains & Plains (3,000m – 7,000m): High-altitude snowy peaks (>120m) and golden plains.
- Mistlands (5,000m – 9,000m): Jagged crags shrouded in ancient mist.
Polar Latitudinal Extremes
- Ashlands (Z < -6,000m): Boiling volcanic southern sea and boiling waters.
- Deep North (Z > +6,000m): Glacial polar expanses introduced in 1.0, home to Kall Fimbulbringer.
- The Great Void (> 10,000m): Endless ocean waterfalls tumbling into the cosmos.
- Save System 1.0: Chunk-based serialization prevents save file corruption.
How to Use the Map Coordinates in Game
You can navigate directly to any coordinate displayed in the viewer using Valheim developer console commands:
- Press F5 in game to open the developer console.
- Type
devcommandsand press Enter to enable cheat mode. - Type
goto [X] [Z](for example,goto 250 -180) to teleport directly to the coordinates. - Use
findbiome DeepNorthto confirm the nearest polar border.
