Gamma for NeoForge
by b1nt1n
Gamma for NeoForge lets a player brighten dark caves, night areas and scenes running a shaderpack by flipping a client-side toggle, with no detour through the video options.
What it does
The mod offers two brightness modes. The main fullbright mode forces the vanilla lightmap to its maximum, while the Brightness mode works on the lightmap and can be set to boost the vanilla brightness or gamma value safely. A separate Night Vision mode applies the normal visible effect and refreshes it before the vanilla ending flicker starts, so it does not flicker during regular play.
Modes and the toggle key are set in a client-side config file, and a key switches between Brightness and Night Vision while the game runs. Previous brightness settings are restored when the effect is turned off. Shader behavior varies with the shaderpack, since the Brightness mode still uses Minecraft's vanilla lightmap, and the mod is useful for mining, exploring, building, taking screenshots and playing with shaders where the normal brightness slider is not enough.
Installation needs only NeoForge and the mod's single file for 1.21.1. The mod is client-side only, so servers do not need it and players do not need a server-side install. Gamma for NeoForge is released under the MIT License and is not open source. Its latest file, 1.0.4, was published on 2026-06-05.

How it compares
Simple Fullbright is client-side only, open source under the MIT License and published for Fabric, Forge and NeoForge across 1.16.5 – 26.3. Per Dimension Brightness Control is client-side only and open source under the GNU General Public License v3.0 only, covering 1.19 – 26.3 on Fabric, Forge and NeoForge, and it can set brightness per dimension. GimmiFullBright is server-side only, is not open source, uses the MIT License and is built for NeoForge 1.21.1 – 1.21.5, so it works on a different side from Gamma for NeoForge.
