Chunky (Forge)

Pre-generates chunks, quickly and efficiently


- 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


You will need OP to use commands.
On a dedicated server, type op <username> from the server console. If using single player, enable cheats.
