Chunky

Pre-generates chunks, quickly, efficiently, and safely

Features

Start one or several chunk generation tasks at the same time (if you want to leverage your CPU more)
Pause chunk generation tasks, saving them for later
Shows detailed information such as chunks processed, percent to completion, ETA, chunk processing rate, etc
Custom world shapes, and optional world border support with ChunkyBorder installed

Permissions

In order to use chunky you will need to either:

Be an operator on a dedicated server. To become an operator, someone with access to the server must run the command op <username> from the server console.
Be in a singleplayer world. In older versions of chunky you may also need to enable cheats for the world. This can be done during world creation, or by using the "Open to LAN" button.
