How do I install Dynamic Brightness?

Install the matching mod loader (Forge, Fabric or NeoForge) for your Minecraft version. Download the .jar. Put it in the .minecraft/mods folder and launch that loader profile. Opens on Modrinth — not every file is mirrored on our own servers.

What Minecraft version does Dynamic Brightness work with?

The listing gives Minecraft 1.21, 1.21.1, 1.21.2, among others. This is the version stated by the author or source site, not something we verified ourselves.

Dynamic Brightness

Which build do you need?

This mod ships a separate file for every mod loader and every version of the game. Pick both, then download — the wrong build installs fine and then does nothing in the game.

I don't know my version or loader

Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.

No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

Idea

Do you set the brightness to maximum to see better in caves?
After that all shadows on the surface are almost completely lost?
This mod is designed to fix that!

Features

Eye Adaption - brightness adapts to the environment.

Configuration

Customizable with Cloth Config:

Eye Adaption Range - How much the brightness will change depending on the environment
Eye Adaptation Speed - How quickly will the brightness adapt to the environment
Dynamic Light Impact - How strongly will Dynamic Light mods affect dynamic brightness

Integration

Future plans

More Dynamic Lights support
Probe visible light sources

Frequently Asked Questions

Can I set the brightness to more than 100%?
No. There never will be an option for that. Main idea is to bring back ambient shadows where it will not impair visibility. And not to cheat. That allows you to use mod in multiplayer.
Does it work with shaders?
Partially. It works with installed Iris, but may not work with enabled shaders due to custom light handling in shader packs.
