The most feature-complete and optimized dynamic lighting mod.

πŸ“– What's this 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.

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).

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.

Frequently Asked Questions

Does LambDynamicLights - Dynamic Lights need to be installed on the Minecraft server?

No. Modrinth marks LambDynamicLights - Dynamic Lights as unsupported on the server side. Install it only in your local Minecraft mods folder. Your server can remain unchanged unless the mod page lists an additional dependency.

Which version and loader does LambDynamicLights - Dynamic Lights require?

Use a file for fabric, neoforge, quilt and your exact Minecraft version. Supported versions include 26.3, 26.2, 26.2-rc-2. Files for different loaders are not interchangeable.

LambDynamicLights - Dynamic Lights is not working – what should I check?

First check the Minecraft version, loader version and required dependencies. Put the .jar file in your local .minecraft/mods folder and remove older duplicates. Because this mod is client-side, adding server RAM will not fix it.
