About this mod Author’s original text

SeedSeer

A tiny utility that reveals the world seed of any Valheim world — client-side, with an optional dedicated server mode.

SeedSeer answers one question every Valheim player and server admin eventually faces: "What seed is this world running?" Install it on your game client and you'll see the seed of any world you join — including dedicated servers you don't control — because every Valheim client receives the world seed to generate terrain locally. Optionally install it on your dedicated server too, and your players can request the seed in chat with /seed.

🌟 Features

🌱 Client-Side Seed Reveal (Works on Any Server)

  • Spawn Message: The first time your character spawns into a world, the seed appears as an in-game message (e.g., [SeedSeer] World seed: "MyWorldSeed" (hash: -123456789)). Toggle with ShowOnSpawn in config.
  • seed Console Command: Type seed in the F5 console at any time to print the current world's seed to the console and HUD.
  • Dedicated Server Friendly: Connecting to a dedicated server? Valheim sends the server's world seed to every client — SeedSeer displays it, even if the server runs no mods at all.
  • Log Output: The seed is also written to BepInEx/LogOutput.log on every world load.

🖥️ Optional Dedicated Server Mode

  • Server Console & Log: When installed on a dedicated server, the seed is printed via ZLog to the server console and LogOutput.log at world load.
  • /seed Chat Command: Any player can type /seed (or!seed) in chat and receive the world seed back as a private whisper — no console access needed.
  • Optional Admin-Only Restriction: Set AdminOnlyCommand = true in config to limit /seed replies to players in adminlist.txt (default: off, everyone can request).
  • -seed Launch Argument Verification: If the server is started with a -seed argument, its value is logged at plugin load so you can confirm the server received the seed you intended.
  • Audited: Every /seed reply is recorded in the server log with the requesting player's name.

⚙️ Configuration

All settings live in BepInEx/config/com.jubaroo.seedseer.cfg:

  • ShowOnSpawn (Default: true) — Client-side: show the world seed as an in-game message on first spawn into a world.
  • AdminOnlyCommand (Default: false) — Server-side: restrict /seed chat command replies to players listed in adminlist.txt.

📦 Installation Instructions

Prerequisite: You must have BepInExPack Valheim (v5.4.2202 or later) installed before installing SeedSeer.

Using a Mod Manager (Recommended):

  • Open your preferred Valheim mod manager.
  • Click the Install with Mod Manager button on this page, or search for "SeedSeer" within the manager's download interface.
  • Ensure BepInEx is enabled.
  • Launch the game — the seed appears when you spawn into a world.

Manual Installation (Client):

  • Click the Manual Download button on this page.
  • Extract the downloaded.zip archive.
  • Move the SeedSeer.dll file into your \BepInEx\plugins\SeedSeer\ folder.
  • Launch the game!

Manual Installation (Dedicated Server — optional):

  • Extract the downloaded.zip archive.
  • Move the SeedSeer.dll file into your dedicated server's BepInEx/plugins/SeedSeer/ folder.
  • Start the server — the seed is printed to the console at world load, and players can use /seed in chat.

🌐 Compatibility & Multiplayer

  • No Server Required: The client-side reveal works on vanilla and modded dedicated servers alike — the server does not need SeedSeer installed.
  • No Client Required: If you only install it on your dedicated server, players need nothing; they can still request the seed via /seed chat.
  • Gameplay Safe: Purely informational — does not alter gameplay, world generation, or network traffic.
  • No Dependencies: Requires nothing beyond BepInEx.

Install & use Install: BepInEx plugin

  1. The archive from playbuff is the mod itself — usually a BepInEx plugin (a .dll or a plugin folder once unzipped).
  2. Recommended: use a community mod manager (such as r2modman) — pick this game, import the mod, and the manager sets up BepInEx and its dependencies for you.
  3. Manual route: install the BepInEx loader in the game folder, then drop the unzipped .dll or plugin folder into BepInEx/plugins/.
  4. Launch the game — the BepInEx console logs every plugin it loads; seeing this mod in the log means it is installed.

Mods with listed dependencies need those installed too, or they will not load. Options are usually changed in-game or in the plugin's config file. In multiplayer, the host and every client need the same mods installed.
