sildurs-shaders.github.io
What it is
Sildur’s Vibrant Shaders is a Minecraft shaderpack extension for the GLSL shader mod, now part of OptiFine. Its Vibrant shaders change the game’s lighting with volumetric lighting, bloom, ambient occlusion, and reflections; the project describes them as maintaining high performance. Free Vibrant downloads include Lite, Medium, High, High-Motionblur, Extreme, and Extreme-Volumetric lighting. Enhanced Default keeps Minecraft’s vanilla appearance while adding shadows, reflections, and godrays, and is described as lightweight and customizable. Fabulous shaders use Minecraft’s built-in shader function and require the Fabulous graphics setting in Minecraft 1.16 or newer. The packs are designed for graphics cards and computers including Macs. Downloads list Minecraft versions 1.7.10 through 26.3, plus Distant Horizons and Voxy support. Installation guidance recommends Iris and Sodium and also provides an OptiFine route. The downloads page lists Vibrant Shaders v2.02, dated September 15, 2026, as the latest Vibrant update.
