How Valheim world generation works
There is no single "Valheim map." Every world is generated procedurally from a seed: a short text string you type when creating a world, or a random one the game rolls for you. The seed and world-generation version determine a new world's layout. Updates to existing worlds and mods can affect locations, so the seed alone does not guarantee a match to an older save.
Under the hood, your seed text is converted into a single 32-bit number, and that number drives the entire generator. That means there are about 4.29 billion possible Valheim worlds (232). Each world is a finite disc roughly 10,000 meters in radius, with the ocean dropping off at the edge. You always spawn near the center in a Meadows biome, beside Eikthyr's sacrificial stones.
Performance and loading times
World generation runs in your browser. The first time you generate a map it downloads the map engine, so the initial load depends on your internet speed. On a fast connection this takes a few seconds. On a slower one it may take longer. Once the engine is cached, switching seeds regenerates the map without downloading the engine again. Overall speed also depends on your device: a desktop or laptop with more RAM will render faster than a phone or older machine.
What the viewer shows
The viewer previews the following layers. Current-game accuracy remains unverified, and individual trees, ore nodes, and runtime creature encounters are not mapped:
- Every biome: Meadows, Black Forest, Swamp, Mountain, Plains, Mistlands, Ocean, plus the Ashlands (always to the far south) and Deep North (always to the far north).
- Boss altars: where to summon Eikthyr, The Elder, Bonemass, Moder, Yagluth, The Queen, and Fader.
- Points of interest: the traders Haldor and Hildir, burial chambers, swamp crypts, frost and troll caves, infested mines, and Fuling villages. Toggle the broad categories and click a marker for its predicted coordinates. Frost and troll caves currently share the Caves filter.
- Coastlines and rivers so you can plan a base, a harbor, and your early sailing routes.
- Two views: flat biome colors, or a “Full Terrain” relief view that shades the elevation so mountains and valleys read in 3D.
How to find your world seed
From Valheim's world-select screen, the seed is shown next to each world. Copy it and paste it above. If you start a new world, roll a Random seed here, preview the world, and reuse the seed in-game when creating a world. The seed is also stored in the world's .fwl save file if you ever need to recover it.
Frequently asked questions
How do I see the map for my Valheim seed?
Copy the seed from Valheim's world-select screen, paste it into the viewer, and select Generate. Copy map link shares that same world.
How many different Valheim worlds are there?
Roughly 4.29 billion. Your seed text is hashed down to a 32-bit number, and that single number determines the whole world, so there are about 2^32 distinct Valheim worlds.
Where do I find my world's seed?
On the world-select screen Valheim shows the seed next to each world. The seed is also stored in world metadata. Paste it into the viewer to preview the map. Save-file import is not available here yet.
Is the generated map exactly what I'll get in-game?
Accuracy against the current game release is not yet verified. World-generation versions, updates to existing saves, and mods can change the result. Runtime encounters such as sea serpents are not predicted. This viewer does not currently import saved-world locations.
Why doesn't the in-game map already show all this?
In Valheim the map starts black and only fills in as you physically explore. A seed viewer reveals the whole world up front, so you can judge a seed before sinking hours into it.
