About this Mod

This mod is an addon for JourneyMap that allows you to divide the map into regions and assign them names and colors.

Panels showing the 3 frontier shapes and the list with collections

Version 3

Big changes are coming in this new version. The features already implemented are Path as a new shape, Collections for organizing frontiers, and an API so that anyone can create a plugin that interacts with MapFrontiers.

The API is published as SNAPSHOT and its design is not yet finalized.

From this version onwards, Forge Config API Port is no longer needed.


 

Features

  • Vertex Frontier: A single polygon in any shape you want. Use the left mouse button to drag vertices. Use the right mouse button to open the menu where you can add and remove vertices.
  • Chunk Frontier: A group of chunks that you can add and remove individually with the right mouse button.
  • Path Frontier: A trail of markers. Use the left mouse button to drag points. Use the right mouse button to open the menu where you can add and remove points.
  • Collections: Organize your frontiers into collections. Make them visible on the map when you zoom out.
  • HUD: Next to the JourneyMap minimap, you can see which frontier you're within. You can edit appearance and screen location in settings.
  • Banner: You can assign any banner you have in your hand to your frontiers. It can be displayed on the map and in the HUD.
  • Permissions: In settings, players with OP permissions can change who can create, modify, and delete global frontiers.

 

Client or Server?

The mod is optional on both sides. It is placed on the client for the player who wants to see and use the frontiers. It is placed on the server so that global frontiers can be created (which can be seen by everyone who has the mod on their client) and so that personal frontiers can be shared with other players.


 

Current limitations

  • Doesn't support vertex frontiers that intersect themselves.
  • JourneyMap moves Minecraft effect indicators with the minimap. MapFrontiers doesn't do that so they end up in front of the frontier indicator.

Frequently Asked Questions

MapFrontiers server crashes on startup – what to do?

Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (26.2). You can switch loaders with one click in the panel.

Is MapFrontiers compatible with fabric and forge and neoforge and quilt?

MapFrontiers officially supports fabric, forge, neoforge, quilt for Minecraft 26.2, 26.1.2, 26.1.1. Note: Forge and Fabric mods are NOT cross-compatible – pick one loader and stick with it. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with MapFrontiers – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if MapFrontiers consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
