Server-side companion for mapping mods. Automatically sets world name in Multiworld mode - no more manual configuration and "world not recognized" messages.
Supported platforms: Fabric, Spigot.
Supported mapping mods: VoxelMap, Xaero's Map, JourneyMap, Rei's Minimap.
Functionality
This mod helps in a specific situation: where you connect to a server that has more than the 3 vanilla dimensions, mapping mods easily get confused and can either mix up the maps or ask you which one you're on. This can happen on many modded servers - but also vanilla servers if there are behind a proxy (Bungeecord/Velocity/etc).
This tool solves this problem by telling the mapping mod which world it's connected to.
Installation
Download a jar from the Releases section and drop it in your mods/plugin folder on the server side. If you're using a proxy (Bungecord/Velocity/etc.) make sure to have it installed on all servers.
The jar works on both Fabric and Spigot - cursed, I know.
Configuration
There's nothing to configure. The mod will automatically read the world name from
your server configuration (level-name on vanilla, dimension name on modded).
One common issue is that all your worlds are named world - you'll have to fix that
for the mod to operate correctly.
