TrueLightFX Shader for Minecraft

TrueLightFX is a custom Minecraft shader based on the open-source Prismarine Shader. This shader aims to enhance the visual experience of Minecraft by adding realistic lighting, shadows, and atmospheric effects while maintaining good performance. With TrueLightFX, players can enjoy immersive gameplay with improved light dynamics, smooth water reflections, and vibrant colors—perfect for both low-end and mid-range systems.

Compatibility:
TrueLightFX might work with the Minecraft versions 1.8.2 – 1.19, but older versions may experience bugs and reduced smoothness. For the best experience, it is strongly recommended to use Minecraft 1.19 or newer.Also I dont recomment using optifine bc of some features that are very buggy on Optfine but on Iris they just work fine!Also please note that I would recommend you to only use Versions of the game where Iris&Sodium still get updates!
