ScalableLux is a performance-enhancing mod for Minecraft, built upon the foundation of the renowned Starlight mod. Its primary purpose is to address and significantly improve the efficiency of light updates within the game's lighting engine. Vanilla Minecraft's lighting system can often become a bottleneck, especially during intensive processes like high-performance chunk generation or when dealing with numerous light sources. This mod aims to alleviate these performance issues, ensuring a smoother and more responsive gameplay experience by optimizing how light propagates and updates across the game world, making it a valuable addition for players seeking to push the boundaries of their Minecraft performance. This mod operates by implementing the core performance improvements found in Starlight and introduces its own enhancements, including additional bug fixes. A key feature is its optional support for parallel light updates, a design choice that dramatically boosts performance in scenarios demanding rapid world generation or experiencing heavy light updates. By leveraging a "stateless" design, similar to Starlight, ScalableLux allows for concurrent processing of light updates, which is crucial for scaling chunk generation beyond traditional limits and is particularly beneficial for dedicated servers that experience substantial player loads and stress on world generation processes. This means faster loading times and a more stable experience, even with complex lighting setups. ScalableLux is designed for broad compatibility, supporting Minecraft versions 26.1-rc-2, 26.1-rc-3, 26.1, 26.1.1, 26.1.2, 26.2-rc-1, 26.2-rc-2, and 26.2. It seamlessly integrates with both the Fabric and NeoForged mod loaders, offering unparalleled flexibility for various modding environments. The mod's installation is entirely optional on both the client and the server, providing users with the freedom to choose where and how they wish to implement its benefits. Whether you're a solo player looking for a personal performance boost or an administrator managing a bustling dedicated server, ScalableLux offers a tailored solution to enhance your Minecraft experience. To install ScalableLux, simply place the mod file into the `mods` folder of your Minecraft installation. For Fabric users, this folder is typically found within your `.minecraft` directory. If you are using NeoForged, the process is identical, with the mod file going into the designated `mods` folder within your NeoForged installation. Before launching the game, it is crucial to ensure that you have downloaded the correct version of the mod that matches your specific Minecraft version and chosen mod loader. Additionally, verify that you have the necessary mod loader (Fabric or NeoForged) already installed and correctly configured to prevent any potential conflicts or errors during startup, ensuring a smooth and optimized gameplay experience.
