Old Lighter
by cintlex
Old Lighter restores the older lightmap renderer for Minecraft Java Edition, bringing back the earlier light colour curve on Fabric and NeoForge.
What it does
The game's lightmap engine was rewritten in a later release, which changed the default light colour brightness curve. This mod reproduces the curve used in the older renderer, as a nearly one-to-one copy of the old colours, while the end flashes and the data-driven light tinting of the new engine are kept.
The mod uses a hybrid approach. It reintroduces the old lightmap without breaking the newer features, and it does not reintroduce MC-225088 or alter night vision, wither dimming or the nether and end colours. A resource pack is bundled with the mod and loads automatically, so no separate setup is needed. Without that pack enabled, lighting will not look correct, so players should keep Mod Resources and resource packs enabled.
Old Lighter needs Fabric API, with a minimum version of 0.145.1 for 26.1, and it works with newer Fabric API builds. The mod is compatible with major optimization mods such as Sodium. It is client-side only and runs on the client without a server install. Builds cover 26.1 – 26.2 on Fabric and NeoForge, and the code is open source under the GNU General Public License v3.0 only.
Key features
Older lightmap curve
Recreates the lightmap renderer as it worked before the engine rewrite, with the older colour and brightness curve.
Tint-based light model

Preserved end flashes
End flashes and the nether and end colours stay in place, while the rebuilt curve replaces the new default.
Bundled resource pack
A bundled resource pack loads automatically, and the lighting is only correct with that pack enabled.

## Info Mojang rewrote the lightmap engine to use UBO's in 1.21.9, switching from a fixed cubic curve light renderer to a more customizable tint based model. While this is great for creators, it unfortunately changed the default color and brightness curve in vanilla we've been used to since Beta 1.8. This mod uses a…
