A huge thank you 🙏

Quanta Shader exists only thanks to **Javier G. Cimarras (`javiergcim`)**
and his amazing project **[MakeUp Ultra Fast]**.

All the heavy lifting — the lighting model, the shadows, the water,
the sky, the clouds, every clever optimization that makes this shader
fast — is his work. This project is just a small, respectful fork:
renamed, cleaned up, and slightly tweaked.

If you like Quanta Shader, please go and support the original author
first. He deserves all the credit. ❤️

PosterizationShader

## **PosterizationShader – Artistic Posterization Shader**

Transform your Minecraft into a stylized poster with this lightweight shader pack!

**What is posterization?** Posterization is an artistic effect that reduces the number of colors in an image to discrete levels, creating a unique visual style with clearly defined color bands instead of smooth gradients.

**Features:**

– Customizable posterization effect (4-32 levels)

– Maximum performance – virtually no impact on FPS

– Full compatibility with Optifine and Iris Shaders

– Supports Minecraft 1.16+

**Configuration:**
Change the POSTERIZATION_LEVELS parameter in the shaders.properties file:

– 4 – Extreme posterization (very few colors)

– 8 – Medium posterization (default, recommended)

– 16 – Light posterization

– 32 – Barely noticeable posterization

**Installation:**

1. Install Optifine or Iris + Sodium

2. Place PosterizationShader.zip in your .minecraft/shaderpacks/ folder

3. Activate the shader in video settings

**Technical Details:** The shader works by quantizing the RGB channels of each pixel at the final rendering stage, which allows for high performance while creating a unique visual effect.
Perfect for:

– Screenshots and artistic content

– Players who want a unique visual experience

– Low-end PCs (shader is very lightweight)

Pixel Rework

Pixel Rework is a polished shaderpack that keeps Minecraft’s vanilla identity intact while improving visual clarity, lighting balance, and overall atmosphere. It focuses on clean, stable rendering with natural-looking daylight, smoother shadow transitions, clearer skies, and carefully tuned water behavior that avoids extreme distortion. The pack is designed to feel familiar, not over-stylized: colors stay true to vanilla, performance remains practical, and visual upgrades are applied with restraint so the world still feels authentically Minecraft.
