ChunkSync
by Vale1c
ChunkSync keeps block changes in step across neighboring chunks, so a placed or broken block shows up in the chunks next to it.
What it does
Placed, broken and updated blocks are copied into the adjacent chunks in real time. The behavior runs on the server, so players join without installing anything. Fabric API is required, and the mod is published for Fabric only, with a single build for 1.21.11, released under the MIT License and not open source.
Key features
Automatic block sync
Placing a block also places it in neighboring chunks, without any command or manual step.
Breakage and updates
Broken blocks and later block updates are mirrored across the same neighboring chunks as placements.
Vanilla client support
Players connect with an unmodified client, since all of the work happens on the server.
