Each chunkloader can load up to 81 blocks in a square with the block in the center loaded chunk. It has options for 1×1, 3×3, 5×5, 7×7, 9×9.

To use BetterChunkLoader you need an Iron block for online only chunkloaders and a Diamond block for offline chunkloaders. To activate the chunkloader you will need a stick.

• Place down the block, anywhere is fine just be aware of the chunk borders so you are loading the expected chunks. (press F9 to see chunk outlines)
• With stick in hand right click on the chunkloader you want to activate. Remember Diamond for offline and Iron for online only.
• Select the appropriate option for the number of chunks you want to load. After this step it should tell you Chunk loader created. You're good to go!
