MapFogCleaner
Automatically fills in small, fully-enclosed fog-of-war gaps on the map as you explore, so tiny unrevealed specks don't clutter an otherwise fully mapped area. Large unexplored zones are left untouche

About this mod Author’s original text
MapFogCleaner
Tidies up your map by automatically clearing tiny, fully-enclosed fog-of-war pockets left behind by the way exploration actually works in Valheim — following paths rather than sweeping every square meter. Those little grey specks sitting inside otherwise fully-revealed terrain get filled in on their own, while genuinely large unexplored areas are always left alone.
How it works
Every few seconds, the mod scans the map's fog data for connected patches of unrevealed area. Any patch small enough to fit within the configured radius gets revealed automatically, exactly as if you'd walked through it — it's real exploration progress, not just a visual trick, and it persists with the rest of your map data. Patches larger than the threshold (oceans, unexplored biomes, anything meaningful) are never touched. The scan is spread across multiple frames so it won't cause hitching, even on worlds with a very large, high-resolution fog map.
Configuration
Available via ConfigurationManager (F1) in-game, or the config file BepInEx/config/sopmehua.valheim.mapfogcleaner.cfg:
- Enabled — turn the mod on/off.
- MaxIslandRadius — the largest enclosed fog patch (approximate radius, in meters) that will be auto-filled. Default 100. Raise it to clean up bigger gaps, lower it to be more conservative.
- ScanInterval — how often (in seconds) to scan for new small patches. Default 4.
- HideCloudShadows — hide the moving cloud shadows on the large map and minimap. Purely visual, doesn't affect fog-of-war or exploration. Default off.
Notes
This only affects your own local exploration data, the same as normal walking-based fog clearing — it doesn't sync anything over the network and doesn't need anyone else to have the mod installed.
Install & use Install: BepInEx plugin
- The archive from playbuff is the mod itself — usually a BepInEx plugin (a .dll or a plugin folder once unzipped).
- 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.
- Manual route: install the BepInEx loader in the game folder, then drop the unzipped .dll or plugin folder into BepInEx/plugins/.
- 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.
