ChunkLoader
A Valheim mod that adds an Observation Column capable of keeping chunks loaded even when no players are nearby — similar to Chunk Loader blocks from Minecraft.
About
ChunkLoader allows farms, breeders, smelters, windmills, and other world systems to continue operating while every player is away.
Each Observation Column keeps its surrounding area loaded. By default it loads a 3×3 grid of chunks (9 chunks total), but this can be changed in the configuration to load only the center chunk.
The column consumes fuel while active (default: Thunderstone). Once fuel runs out—or the loader is manually disabled—it stops keeping chunks loaded and its emission changes to indicate the inactive state.
Features
- Keep production running while players are away.
- Continue processing crops, animals, furnaces, windmills, and other world objects.
- Configurable fuel system.
- Configurable per-player placement limit.
- Supports loading either 1 chunk or 9 surrounding chunks.
- Toggle Chunk Loaders on and off without destroying them.
- Visualize the loaded area with configurable color and duration.
- Remaining operating time is shown directly on the minimap pin.

Configuration file:
BepInEx/config/com.Frogger.ChunkLoader.cfg

How Fuel Works
Each fuel item powers the Chunk Loader for the configured amount of real time.
A Chunk Loader remains active only when:
- it is enabled, and
- it has fuel (unless Infinite fuel is enabled).
Disabled Chunk Loaders consume no fuel and do not keep chunks loaded.
Minimap
Every Chunk Loader is displayed on the minimap.
- Active Chunk Loaders use the active icon.
- Disabled or out-of-fuel Chunk Loaders use the inactive icon.
- Active loaders display their remaining operating time as the pin label.
Installation
Install the mod on both the server and all clients.
Configuration is controlled by the server to ensure all players use the same settings.
