Aurelia Shaders pour Minecraft 1.21.1, 1.21

Aurelia

Golden hour, all the time.

Aurelia is an original shader pack with a warm, cinematic mood and a vibrant palette — soft light, long shadows, and color that glows without blowing out. Built from scratch, tuned by eye, and it runs on both Iris and OptiFine.

Features

• Soft PCSS shadows — variable penumbra, colored tinting through

stained glass

• Global illumination + ambient occlusion — one-bounce GI that

keeps interiors and cave mouths grounded

• Emissive light spill — torches, glowstone, lava, and nether

portals wash light onto the blocks around them

• Volumetric sky — raymarched clouds, god rays, and morning ground

fog

• Water worth swimming in — waves, screen-space reflections,

caustics, teal depths, and regional water colors

• PBR two ways — full labPBR resource-pack support, plus integrated

PBR for vanilla blocks: reflective metals, polished stone, and glowing ore veins (coal embers and Nether ores included)

• Biome atmosphere — per-biome tinting and particles: fireflies,

falling petals, spores, blowing sand

• Cinematic image pipeline — filmic tonemapping, auto-exposure,

soft bloom, TAA

• Quality of life — held-item dynamic light, entity-shadow toggle,

four performance profiles

Requirements

• Minecraft 1.17 – 1.21+
• Iris 1.6+ (recommended) or OptiFine HD U
• The default HIGH profile targets high-end GPUs — use MEDIUM or

LOW on weaker hardware, ULTRA for screenshots

Installation

• Install Iris (recommended) or OptiFine.
• Drop Aurelia-v1.0.0.zip into .minecraft/shaderpacks/ —

don't unzip it.

• Options → Video Settings → Shader Packs → select Aurelia.

Iris or OptiFine? Both work. Iris is recommended: better performance and full regional water detection (OptiFine gets a limited version).

My FPS is low. Switch to the MEDIUM or LOW profile in the shader options, or lower the shadow map resolution.

Does it work with resource packs? Yes — any pack. With a labPBR pack you also get real normals, smoothness, and metals.

Can I use it in videos/screenshots? Yes, freely. Credit with a link to this page is appreciated.

Can I reupload or bundle it? No — see the license. Link to this page instead.
