BlueMap Folia Regions

A Paper plugin that visualizes Folia's threaded tick regions on BlueMap's web map in real time.

Overview

Folia splits the Minecraft world into independent regions that tick in parallel across multiple threads. This plugin renders those region boundaries as polygon overlays on BlueMap, giving server administrators a live view of how their world is partitioned.

Each region marker displays:

• Number of sections and chunks
• Entity and player count
• TPS (Ticks Per Second)
• MSPT (Milliseconds Per Tick)

Markers refresh every 5 seconds automatically.

Requirements

• Folia or Canvas server (1.20+)
• BlueMap plugin installed

Installation

1. Download the latest release.
2. Place the .jar file into your server's plugins directory.
3. Restart the server.

The "Folia Regions" marker set will appear on your BlueMap (hidden by default — toggle it on from the map sidebar).

Building

./gradlew build

The compiled jar will be in build/libs/.
