WorldPreGenerator

World Pre-Generator

Pre-generate Valheim world zones before exploring them. The mod uses the game's

ghost-zone path and works in controlled batches, so the world can be prepared while

the host follows progress.

Benefits

• Reduces pauses and processing spikes caused by generation during exploration.
• Leaves terrain, locations, and structures ready before players arrive.
• Keeps map exploration and exploration-related achievements tied to manual play.
• Saves progress at configurable intervals, allowing an interrupted generation to

continue later.

• Provides independent checking, time estimates, and safe cancellation.
• Binds the routine to the active world name and cancels automatically when returning

to the menu.

• Allows only one generation at a time; checking can follow an active generation.
• Displays which zones have been generated on the M map without revealing hidden

terrain.

• Restricts the map grid and management controls to the host or an authorized admin.
• Works in local worlds, multiplayer hosts, and dedicated servers. In a dedicated

connection the modal sends actions to the server, which keeps the counters and

generates the dedicated save.

*The grid shows zone state without revealing hidden terrain: green means generated and

yellow means still missing.*

package layout

The ZIP uploaded keeps README.md, manifest.json, and icon.png

at its root. The screenshots are also included in images/ for local previews and

offline distribution. The README uses absolute HTTPS image URLs because

does not resolve relative links to files inside a package page:

Do not move the screenshots into BepInEx/plugins. If you replace the hosted images,

keep direct HTTPS URLs that return PNG files and update the two Markdown links above.

Installation

• Install BepInExPack Valheim.
• Extract the contents of this ZIP into the Valheim folder.
• Confirm that the file is at BepInEx/plugins/WorldPreGenerator/WorldPreGenerator.dll.
• Start the game through your mod manager.

BepInEx Configuration Manager is optional. When installed, it exposes the mod options

inside the game.

How to use in game

• Enter the world as a local player, host, or administrator.
• Open the pause menu with ESC and select Pre-generate world.
• Check Complete world, or clear it and enter a radius in metres.
• Click Check zones to update the generated and missing zone totals.
• Click Generate missing zones to start the cascade.
• The progress bar, counters, and estimated time update every 5 seconds.
• Use Close to hide the modal while generation continues. Use Cancel to stop

generation and save the progress already completed.

The host can check zones while a generation is active. Checking never starts a second

generation.

When leaving the world, the routine is cancelled before the scene changes and saved

progress is preserved. When entering another world, the modal state and counters start

clean; use Check zones to read that save's state.

Map grid

Enable Map grid in the modal and open the map with M:

• green: zone already generated;
• yellow: zone still missing;
• transparency is reduced under fog to preserve the unexplored map;
• the grid shows generation state only and does not mark the map as explored;
• only the host or an authorized administrator can enable and view the grid;
• on a dedicated server, colors come from a compact snapshot of the server's

authoritative save state; generated zones appear green even if the client has not

loaded them locally;

• points-of-interest icons stay hidden until the area is explored manually when

HideUnexploredLocationIcons is enabled.

Dedicated server

Install the plugin in the dedicated server's BepInEx/plugins folder as well. The

server version must show Loading [World Pre-Generator
