How to choose your 7 Days to Die map, world size and seed

Set World on the Settings tab, Game Settings page. For a random map also set Random World Seed and Random World Size. Restart the server. Switching maps starts a separate save, and your old world stays on disk.

The maps

Switch the map

1. Open your server in the panel, click the Settings tab, then Game Settings.
2. Choose the map in World.
3. For Random map from your seed, type a Random World Seed and choose a Random World Size.
4. Click Restart now.

Seed and size

• Random World Seed: any word or number, up to 32 characters: letters, numbers, spaces and _ . -. The same seed and size always build the same map, so a friend who knows them can see it too. A new seed builds a different map.
• Random World Size: Small (6144 m), Medium (8192 m) or Large (10240 m). A bigger map takes longer to build and gives players more to explore.

Both are used only with Random map from your seed.

The first start of a random map

The first start with a new seed or size builds the terrain, which takes several minutes. Do not stop the server while it does. The map is stored in .local/share/7DaysToDie/GeneratedWorlds, so later starts reuse it.

What happens to your current world

Each map keeps its own saves, in .local/share/7DaysToDie/Saves, one folder per map with your Save Name inside. Switching World starts a fresh world on the new map and leaves the old one where it is. Set World back, with the same seed and size for a random map, to play the old one again.

Characters belong to a save, so players start new characters on the new map.

To restart on the same map instead, see How to start a new world on your 7 Days to Die server. For every setting, see 7 Days to Die server settings: every option explained.
