Team Map Sync

Team Map Sync

Players on the same team share one map: what anyone explores shows up for everyone, plus shared map markers. Works with Host World and dedicated servers. No other mods required.

Features

• Live shared exploration: what a teammate uncovers appears on your map within a few seconds, wherever you are. Terrain changes they see (mined walls, new buildings) are synced too.
• Catch up after being away: the server keeps one merged map per team. When you join, it fills in everything your team explored while you were offline.
• Your earlier exploration counts: when you join a team (or install the mod into an existing world), the map you had already explored is shared with the team.
• Team markers: tick Share with team when editing a map marker. Teammates see it within seconds, and edits and deletions sync. Unticked markers stay personal.
• Built to stay out of the way: the server only relays already-compressed data; decompression, merging and saving run on background threads, and transfers are bandwidth-capped.

How to use

• Everyone (server and every player) installs the mod.
• Create or join a team in game. Sharing is per team; players without a team are not affected.
• Explore. To share a marker, open the marker editor on the map and tick Share with team. New markers remember your last choice.

Notes

• Leaving or switching teams keeps the map you already have; the old team's shared markers are removed and the new team's map is sent to you.
• A team can have up to 500 shared markers.
• The team map is stored by the server in its data folder (teammapsync/<world ID>); your personal map files only receive the shared tiles.
• Pure black map tiles count as unexplored, the same as in the base game's own map files.
