AstraLex started as a BSL edit and turned into the most option-dense pack in the ecosystem. Vivid colour, strong bloom, cartoon-leaning skies, and a settings menu that borders on absurd — there are toggles here for effects most packs never expose at all. If you enjoy tuning a shaderpack as much as playing with one, this is the playground. All Rights Reserved, so download it from LexBoosT's official page.

How to install AstraLex Shaders

1. 1Install a shader loader for Minecraft 1.16.5 – 26.2 — Iris (pairs with Sodium) or OptiFine. AstraLex Shaders is a shaderpack, so it needs a loader to run.
2. 2Download the AstraLex Shaders .zip from the button above — keep it zipped. Its licence doesn’t permit re-hosting, so that button takes you to the official modrinth.com page — always the newest build, straight from the author.
3. 3Drop the .zip into your .minecraft/shaderpacks folder (%appdata%\.minecraft\shaderpacks on Windows, ~/Library/Application Support/minecraft/shaderpacks on macOS).
4. 4Launch the game, open Options → Video Settings → Shaders, and select AstraLex Shaders.
