Chunk By Chunk
Creates a world with a single chunk, and allows additional chunks to be added over time
The experiment went awry. The world is gone... sealed away or lost to the void. You just managed to activate a failsafe in time, saving but the smallest portion of the world. But there is still hope - perhaps the world can still be repaired - chunk by chunk.
Chunk By Chunk is a mod that starts the world with just a single chunk (16x16 column of world), but provides the ability to grow the world, adding additional chunks over time. Key to this are World Cores - found hidden at the bottom of each chunk. World Cores can also be used to build a World Forge, which provides the ability to refine raw dirt and stone into more World Cores.
There are two options for how the generated - missing chunks are either empty (making a skyworld), or are replaced with bedrock (sealing them).
In Forge and Fabric you can now configure Chunk By Chunk from the main menu, using the Mods... menu prior to creating a world to configure the settings for that world. For fabric this requires the Mod Menu mod. For Quilt this is not available yet. On first run a config file is generated in the defaultconfig folder that can be modified for the same effect.
