Flux Dynamic Light

A lightweight, high-performance, and lag-free dynamic lighting addon built specifically for Minecraft Bedrock Edition (1.21.x+).

Tired of placing hundreds of torches while mining in dark caves? Just hold a torch, lantern, or any light-emitting item in your hand or off-hand, or toss it into a dark ravine, and watch the world illuminate around you smoothly in real time.

Achievement Friendly: does not disable Xbox Achievements/Trophies. Freely usable in survival worlds, Realms, or long-term playthroughs while still earning achievements.

Highlights

• 100% Achievement Friendly: no experimental toggles needed, safe for achievement-enabled worlds.
• No Experimental Toggles Required: no need to enable Beta APIs, Holiday Creator Features, or any other experimental toggle. Just activate the packs and play.
• Centralized Lag-Free Engine: built with an optimized single-loop scheduler and smart player-priority suppression, so dropped items and multiplayer lighting won't cause block-update lag or stutter, even on large servers or Realms.
• 100% Vanilla Safe Menu: the settings menu is accessed with a regular vanilla stick named fluxmenu (or via /scriptevent flux:get_config), no risky custom items that break on game updates.

Features Overview

• Dynamic Hand Lighting: walk around dark caves with light seamlessly following you.
• Full Off-hand Support: hold a pickaxe or sword in your main hand while lighting up caves from your off-hand.
• Quick Off-hand Switch: right-click/hold a light source into the air to instantly swap it into your off-hand.
• Dropped Items Lighting: toss torches or glowstone down ravines or deep pits to inspect the bottom before jumping down.
• Smart Light Prioritization: automatically prioritizes the brightest source between mainhand and offhand, preventing flickering between nearby players and dropped items.
• Interactive 2-Level Settings UI: complete control over light settings, active dimensions, dropped item limits, and auto-offhand mechanics.
