# ZombieHorrorShader
**ZombieHorrorShader** is a lightweight post-processing shader pack for **Iris** and **OptiFine** designed to turn your Minecraft world into a gritty, suspenseful zombie apocalypse.
Instead of requiring heavy custom resource packs or complex mod setups, this shader handles everything dynamically. It alters the game's colors to create a cold, desaturated, horror-movie aesthetic while automatically forcing the eyes of hostile and passive mobs to glow blood-red in the dark.

## Features
* **Atmospheric Night Lighting:** Deep shadows are lifted slightly with a cold, pale-blue "ambient moonlight." This keeps the night incredibly spooky and suspenseful while ensuring the terrain remains navigable and playable.
* **Sickly Movie Palette:** The game's colors are desaturated and shifted toward a pale, greenish-grey tone. Warm lighting from torches, lanterns, and fire remains vibrant, creating a stark visual contrast.
* **Automatic Red Glowing Eyes:** No resource packs required! The shader automatically isolates the eyes of key mobs and forces them to glow bright, emissive red in the dark:
* *Zombies, Skeletons, Strays, Husks, Drowned, and Wither Skeletons*
* *Creepers*
* *Pigs, Cows, Sheep, and Chickens*
* **Smart Pixel Targeting:** The glowing eye feature uses model height and color-detection checks to ensure only the actual dark pupils of the mobs glow, preventing any red bleeding on their bodies, legs, or armor.
* **Vignette & Film Grain:** A subtle, animated VHS-style film grain and a dark vignette frame the screen to create a claustrophobic, retro horror atmosphere.

## Performance
* Because this shader operates purely on a lightweight post-processing and entity rendering pipeline, it has an incredibly minimal impact on performance (FPS), making it highly optimized for lower-end systems and large modpacks.
* Compatible with standard vanilla and modded zombie entities from popular mods (such as *Rotten Creatures*, *The Graveyard*, *Mutant Monsters*, and *Born in Chaos*).
