About this Mod
Chunk Loader
With Chunk Loader Datapack the Chunk Loader is added to the game. With it - surprise - you can permanently load chunks.
This means that you can be anywhere in the world, while the chunk in which the Chunk Loader is placed is still loaded.
In order for the Chunk Loader to load the chunk, it needs 3 Redstone Dust per minute. To fill, simply right-click and place it inside. As soon as there is no more Redstone dust inside, the chunk loader stops working and the chunk will be unloaded until new Redstone dust is added.

Chunk Loader server crashes on startup – what to do?

Chunk Loader officially supports datapack, fabric, forge, neoforge, quilt for Minecraft 1.21.1, 1.21, 1.20.1. Note: Forge and Fabric mods are NOT cross-compatible – pick one loader and stick with it. The Mado dashboard automatically detects incompatible loader combinations.
Server lagging with Chunk Loader – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Chunk Loader consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge.
