Terrain commands (terrain.*)
The real Rust Console-Edition terrain.* + env.oceanlevel generation commands, at their stock defaults. Changing one reshapes the preview (coast, beaches and biomes respond). Approximate, not Facepunch's exact gen. Single tab only.
Paste commands
Paste Rust commands or a map URL and it fills the fields + renders. Understands server.seed / server.worldsize and any terrain.* / env.oceanlevel command, in boot, a / b / c or ?seed=&size= form.

Generate your first map

Pick a seed or roll a random one — terrain, biomes, cliffs and beaches render in seconds.
