Rainbow Shader is a fully custom, original visual overhaul for Minecraft Bedrock Edition, built entirely on Mojang's official Vibrant Visuals deferred rendering pipeline. Every value in this shader — sky color, lighting curves, color grading, water — was independently designed for this project. It isn't a fork or reskin of any other shader; it's built from the ground up using Mojang's public render-control JSON system.
β¨ Features
π Dramatic Multi-Hue Sky
Instead of a single flat color, the sky shifts through a rich, colorful gradient across the full day-night cycle — deep indigo-violet at night, soft magenta-pink before dawn, warm orange at sunrise, a fresh sky-blue morning, vivid cyan-blue at midday, and a rich violet-pink dusk fading into fiery orange-red at sunset. The result is a constantly evolving, dreamy, rainbow-like atmosphere that never looks flat or repetitive.
βοΈ Bold, Glowing Sun
Boosted Mie scattering creates a strong, soft bloom around the sun, especially dramatic near sunrise and sunset, giving every golden-hour moment a magical, glowing quality.
π¨ Rich, Punchy Color Grading
Saturation, contrast, and gamma are carefully tuned across shadows, midtones, and highlights using a proper Hable tone-mapping curve — colors pop and feel alive without ever blowing out or looking unnatural.
π Colorful Night Sky
Moonlight shifts between a cool blue and a soft teal-green tint across the night cycle, keeping night exploration atmospheric and visually interesting rather than flat and dark.
π Lively, Animated Water
Custom wave motion and a hand-crafted, uniquely tinted animated caustics texture (fully original, procedurally generated) bring oceans, rivers, and lakes to life with real motion and a soft colorful shimmer.
π Balanced Soft Shadows
Clean, soft-edged shadows keep the world grounded and three-dimensional without harsh, distracting edges.
π Works Across Every Dimension
Because this shader tunes the game's core lighting and atmosphere engine, it enhances the Overworld, Nether, and End consistently — no extra setup needed per dimension.
βοΈ Requirements
- Minecraft Bedrock 1.21.80+
- Vibrant Visuals experimental toggle enabled at world creation (cannot be turned on for an existing world — create a new world with it enabled)
- A device capable of running Bedrock's deferred rendering pipeline
π₯ Installation
- Tap the
.mcpackfile to import it into Minecraft - Go to your world's Resource Packs settings and activate only Rainbow Shader (disable any other shader/resource pack that changes lighting)
- Create or load a world with Vibrant Visuals enabled
- Enjoy — no sliders, no extra setup, it's active the moment you enable it
π‘ Notes
This shader uses smooth, physically-guided color transitions (via Mojang's lighting engine) to achieve its vivid, multi-hue look rather than painted sky textures — meaning it stays lightweight and fully compatible with the standard Vibrant Visuals pipeline.
