Lux Comapnion
by SappyEddie
Lux Companion lets each player wear a glowing companion that follows them through the world and emits dynamic light.
What it does
Seven built-in archetypes are available, including Fairy, Drone, Wisp, Swarm, Worn, Lantern and Beacon, each with its own idle animation and hover-based, physics-driven motion. A companion can be recolored with full RGB tint or quick-pick presets, resized, repositioned and rotated through transform sliders, and set to a Steady, Orbit or Agile behavior profile. Press L at any time to switch its light off.
Companions cast real light through LambDynamicLights, so caves, ravines and late-night builds are lit by the companion itself. The Companion Workbench, opened with O, handles these choices, and custom companions can be added by dropping a GeckoLib model, texture, animation and optional glow mask into the luxcompanion/companions folder. Creating a companion from code is a separate step the author notes as required.
Lux Companion is client required and server optional, so players install it and can enjoy a server without asking the admin. It runs on Fabric and NeoForge for 1.21.1 and is released under All rights reserved, so it is not open source. The file version is 1.0.0 for both loaders, published 2026-07-04.
