Lightweight Skybox Shader
A minimal, high-performance skybox shader focused purely on atmospheric beauty with almost zero performance cost.
Summary
Ultra-lightweight skybox shader that replaces the vanilla Minecraft sky with a clean, cinematic night sky featuring dense stars, soft nebulae/aurora streaks, and subtle volumetric light rays. Designed for maximum FPS (especially on low-end and mobile devices) while still delivering a premium atmospheric look.
Description
This is a pure skybox-focused shader — no complex lighting, shadows, or water effects. It only touches the sky, making it one of the lightest visual upgrades available.
Features:
Dense, sharp starfield
Soft multi-colored aurora / nebula streaks (greens, purples, and blues)
Subtle volumetric light rays and glow around bright celestial points
Clean night-time atmosphere with smooth color gradients
Extremely low overhead — ideal for low-end PCs, integrated graphics, and mobile
Perfect if you want a beautiful night sky without sacrificing performance. Just drop it in and enjoy the view.

Install Iris (with Sodium) or OptiFine for your Minecraft version: shaders need one of them.
Download the .zip file from Modrinth. Do not unzip it.
In Minecraft, open Options, then Video Settings, then Shader Packs, and click Open Shader Pack Folder.
Drop the .zip file into that folder, pick Celestia in the list and click Done.
Shaders are heavy on the graphics card. If the game gets slow, pick a lower profile in the shader settings.
