About

Description

Server-side addon that shows FTB Chunks team claims on your BlueMap web map. See who owns what at a glance, with rich team info popups.

⚠️ 1.20.1 build requires Java 21 and BlueMap 5.12+. It will not work on Java 17 or older BlueMap versions.

What it does

Renders every claimed chunk from FTB Chunks as a colored marker on BlueMap
Both flat 2D and 3D extruded marker layers, toggleable per-map
Groups adjacent claims into single regions (no per-chunk marker spam)
Click a claim to see team info: name, color, members (online/offline), avatars, area, center coords
Live updates when chunks are claimed / unclaimed
Persists state across restarts so the map is correct immediately after server start
Works across all dimensions (Overworld, Nether, End, custom)

Commands

All under /blueftbchunks (requires permission level 2 / op):

Command	What it does
`/blueftbchunks reload`	Full memory flush, reload from disk, re-sync with FTB Chunks, re-render all markers
`/blueftbchunks data save`	Force a save of the current claim state to disk
`/blueftbchunks data init`	Clear data, reload from file, re-sync — without touching markers
`/blueftbchunks data status`	Show how many chunks / teams / dimensions are tracked, and time since last save

Config

Created on first run at config/blueftbchunks-common.toml:

# Toggle FTB Chunks integration entirely.

ftbChunksEnabled = true

# How often to re-sync with FTB Chunks (ms).

claimUpdateIntervalMs = 60000

# Wait this long after server start before first claim sync (ms).

# Increase if claims don't show up on restart.

startupDelayMs = 3000

Saved claim state lives in <world>/blueftbchunks/claim_data.json. Auto-saves every 5 minutes if dirty.

Notes

This is a fork / port of FTB Chunks for BlueMap by Fabra, originally written for NeoForge 1.21.1. This release is a backport to Forge 1.20.1 for servers on the 1.20.1 line who want claim visibility on BlueMap 5.12.
