📋 About This Mod

# ScalableLux A Fabric mod based on Starlight that improves the performance of light updates in Minecraft. ## Why does this fork exist? - Starlight is no longer maintained as a mod (https://github.com/PaperMC/Starlight/commit/cca03d62da48e876ac79196bad16864e8a96bbeb). - The performance of vanilla lighting engine is still a bottleneck for high-performance chunk generation. - The base Starlight is still (<https://gist.github.com/Spottedleaf/6cc1acdd03a9b7ac34699bf5e8f1b85c#light-engine-performance-changes-in-120-from-vanilla>), allowing the chunk system to scale beyond 24 threads. - Starlight's "stateless" design allows for parallel light updates, further widening the performance gap. It is still (https://gist.github.com/Spottedleaf/6cc1acdd03a9b7ac34699bf5e8f1b85c#is-starlight-obsolete). Therefore, it is still important for Fabric or other modded servers with plenty of players. ## What does this fork do? - Contains all the performance improvements from Starlight with additional bug fixes. - Optionally allows for parallel light updates, bringing significant performance improvement in high-speed world generation and heavy light updates scenarios.
