Starlight Legacy

Which Minecraft do you have?

Every version of the game needs its own build. Pick yours, then download — the wrong build installs fine and then does nothing in the game. This mod is built for Fabric only.

Minecraft 1.15–1.15.2Newest
Minecraft 1.14–1.14.4

⬇ Download for 1.15–1.15.2 ⬇ Download for 1.14–1.14.4

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.

Starlight Legacy

An unofficial backport of the Starlight mod for Minecraft 1.14.x and 1.15.x

Starlight was developed for higher scale dedicated servers, as they suffered performance problems due to how ungodly slow the light engine was. The only solution was to create an extremely invasive mod which rewrote the entire light engine. I ported the mod to fabric so that I can update it during snapshots, and decided that publishing it for all users, especially client users, would be beneficial. However, it does have the downside of being an invasive mod: Being invasive didn't affect higher scale servers because they run on Bukkit.

Further reading on the technical details of how Starlight achieves its performance can be read here: TECHNICAL_DETAILS.md

If you're looking for 1.16+, check out Starlight's Modrinth page or GitHub, and consider supporting the mod's original creator, Spottedleaf
