Ultimate Brightness
Ultimate Brightness raises the in-game light level to a maximum of 1500%, so caves, underwater areas and nighttime scenes stay readable without torches.
What it does
Dark shadows are removed by the client-side brightness setting, which lights deep caves, underwater spaces and night-time environments evenly. Players can see everything clearly without first crafting or placing torches, a fullbright effect that the mod keeps lightweight. The mod runs only on the client, so a server does not need it and players join without changing anything on the server side.
The mod requires Polytone on every loader. On Fabric and NeoForge, the version of Polytone needed is the one for builds below 26.2, and builds from 26.2 onward use a different dependency set. Forge builds need OptiFine instead of Polytone. Files are published for Fabric, Forge, NeoForge and Quilt, with 33 release versions 1.14 – 26.3 and the latest file for 1.21.11 on Fabric, NeoForge and Quilt.
The mod was first published on 2026-08-13 and last updated on 2026-09-25. Its code is not open source and is released under All rights reserved.
Key features
Maximum brightness of 1500%
The brightness setting can be raised to a maximum of 1500%, far beyond the vanilla gamma limit.
Dark areas fully lit
Shadows in caves, underwater and at night are removed, so terrain stays visible without any light sources.
No torches needed
Players can explore dark spaces without crafting or placing torches, since the light is applied on the client.
Lightweight client change
The mod changes only how the client draws light, so it adds little overhead to the game.
