How to change the map seed in Rust

Add +server.seed 1337 to the server's launch options to generate a different procedural map. Each seed and world size pair makes its own map.

server.seed

Sets the seed for procedural map generation; each seed and size pair makes a different map.

+server.seed <number>

Examples

+server.seed 1337

Generate the map for seed 1337.

+server.seed 12345 +server.worldsize 3500

Seed and size together.

Arguments

numberRequired: Whole number used as the generation seed.

What it does

The same seed and world size always produce the same map, so you can preview candidates on map sites before a wipe. Set it on the launch line; a new seed means a new map and therefore a map wipe.

The game's own description: Seed value used for procedural world generation; changing this produces a completely different map layout

Run it on your server

Type it in the server console or send it over RCON; admins can also use the F1 console in game. To keep a setting, run server.writecfg after changing it, or put it on the launch line as +name value.
