MapSyncer-for-XaeroWorldmap

The mod runs on a server and syncs the areas players have explored into each client's Xaero's World Map. Xaero's World Map is required on the server, and the mod is built to work with pre-generation tools such as Chunky, which are recommended alongside it. It supports dedicated servers, integrated servers, single-player worlds and LAN sharing. On an integrated server, the map cache already stored by the host is reused, which avoids converting it a second time.

Scanning can work by dimension. Dimension arguments accept the overworld, the nether, the end or any mod dimension ID such as twilightforest:twilight_forest. A downward scan reads the heightmap, while a fixed-height scan covers a set band of Y levels. An incremental update adds only newly explored chunks, and a dimension scan covers a whole dimension at once. The mod also works with the Xaero's World Map Minimap.
