Adds dynamic lights to Minecraft as the most feature-complete and optimized dynamic lighting mod.
The most feature-complete and optimized dynamic lighting mod.
It's dark outside, extremely dark...
You can't see a lot in the darkness, you wish you had a torch,
or a lantern to hold and see in the light...
And this is now possible with this mod as it adds dynamic lights to the game.
You can see in the darkness thanks to your torch now!
This mod adds dynamic lights to Minecraft. Dynamic lights are lights created by an entity holding an
item which makes light as a block, or created by an entity on fire, etc.
Searching other mods to replace OptiFine? Check out this list!
Dropped items which already emit light as a block, will also dynamically emit light!

Light is emitted when entities hold light emitting items.


Any entity on fire will emit light!


Creepers can make their imminent explosions more apparent through a progressive emission of light!

The infamous glow squids finally glow in your world!

Wait... what? Lasers?! They do pack a punch...

Fireflies particle will emit light as they fly!

As of v4.0.0.


Using this mod is very simple!
On Fabric, install it in your mods folder along with Fabric API and ModMenu, (and Sodium if wanted for better performances).
On NeoForge, install it in your mods folder (and along with Sodium if wanted for better performances).
It will work as-is. If you want, you can configure the mod through its settings screen by heading to the video settings or via the mods list.
