Cursed Shader pack

This Shader Pack makes things look Totally Cursed!! (SuperMJ767 I’m Looking at you) It looks SUUUPER cursed, as the name suggests. Check out the gallery if you want to know what it looks like. This pack needs Iris shaders to run.

Cursed Fog

CTR VCR

The CTR VCR shader brings the nostalgic feel of old CRT monitors and VHS tapes to your Minecraft experience, adding subtle but impactful visual artifacts and distortions. Inspired by the retro charm of analog technology, this shader introduces static noise, light distortions, chromatic aberration, scan-lines, and more to give the game a vintage, glitchy aesthetic. While these effects evoke a sense of retro realism, they are finely tuned to ensure they don’t overwhelm the visuals, making the shader perfect for regular gameplay. Enjoy the blend of modern gameplay with a retro-futuristic vibe that keeps the world immersive, stylish, and entirely playable.


### Uncut gameplay using the shader (v0.0.1) in Nostalgic Craft v0.1.3o

—

The shader effects were originally a GLSL shader written for Unity in 2023, but were ported to minecraft shader.

Crusher

This shader can reduce both color count and resolution of the image (each function can be toggled on/off for your liking, see gallery for previews)
# Colors
Decreases the amount of colors that is displayed on the screen. This limits each channel to a certain number of values (the value set in settings + black).
For example, if you set the color amount to 2, each color channel will now be able to be at only 0, 127 and 255.
You can also toggle between RGB and HSV modes to change how colors are changed.
## Dithering
This option applies 4×4 bayer matrix dithering to the image which makes the colors appear much smoother but introduce more flickering. Obeys color count and pixel size
# Pixels
Enlarges pixels and in turn decreases the resolution. The large pixels do not average the color of underlying normal pixels, rather pick the color of the top left pixel.
**Larger pixel sizes might create flickering on farther objects**
# Anti-flicker
Decreases flickering on large pixel sizes by averaging colors inside pixels. May decrease performance.
# Corruption
You can enable corruption to make your game look like the universe is getting shut down. **DO NOT USE** if you are photosensitive, it creates **LOTS** of flashing lights.

Fun Fact: this option originated as a failed implementation of the anti-flicker feature, and one of my friends suggested it to be added as a separate option

“I don’t know why anyone would want to use these lmao” – Developer

Download if you dare, but don’t say we didn’t warn you. This isn’t about making Minecraft pretty – it’s about making it horrifying.

CRT Shader

### CRT Shader aiming to give Minecraft a retro style!
Current features include:

– Imitating Pixels
– Lens Distortion
– Chromatic Aberration and Bleed
– Posterization
– Scan Line

### Customization
While there still are limitied options I aimed to add as much customibitlity as possible giving you the ability to tweak most features to your liking 😀

### Warnings

This shader should work with Optifine and Iris from 1.8.9 – 1.20.1, if you encounter any issues you can allways report them 😀

Also from experience this shader does strain your eyes if you play with it on for hours on end.

The appearance may not be the best in images as it is best experienced in game.

### Installation
– First you need to install either OptiFine or the Iris mod to be able to load shaderpacks. (Choose Iris if you are unsure)
– Then you need to launch the game, and get to the Shaderpacks/Shaders menu in Video Settings.
– Open the shaderpacks folder by clicking the button in the menu.
– Download the CRT Shader and put it in the shaderpacks folder.
– Get back in the game, and choose CRT_Shader in the shaderpacks menu. (Refresh the menu if it doesn’t appear)

CRT Monochrome Shaderpack

# CRT Monochrome Shaderpack

> *”End of Line.”*

**CRT Monochrome Shaderpack** is a lightweight GLSL shader pack for Minecraft Java Edition (Iris/OptiFine) that replicates the high-contrast, phosphor-display aesthetic of early 80s computing.

It replaces standard rendering with a strict two-tone wireframe/threshold visualization, simulating a monochromatic CRT monitor inside the game.

## 🖥️ Visual Style

### The “P1″ Phosphor Aesthetic
By default, the pack utilizes the **”P1 Apple Green” (#33FF33)** color scheme, mimicking the high-persistence green phosphor monitors of the Apple II era. The world is rendered as a stark contrast between illuminated geometry and a pure black void.

### CRT Emulation
The pack includes a fully procedural CRT post-processing stack:
– **Screen Curvature:** subtle geometric distortion to mimic a curved glass tube.
– **Scanlines:** Horizontal beam lines that scroll slowly with time.
– **Chromatic Aberration:** Slight RGB channel separation at the screen edges.
– **Vignette:** darkening at the corners to simulate tube depth.

## ⚙️ Technical Features

– **Depth-Based Rendering:** Uses Sobel Edge Detection and luminance thresholding on the depth buffer to generate outlines and solids.
– **Optimization Friendly:** Extremely low GPU overhead. Disables standard lighting, shadows, and PBR calculations.
– **”Hall of Mirrors” Fix:** Includes a custom Sky Shader module that forces a depth buffer clear. This prevents the “smearing” artifacts common when using optimization mods (like Radon/Sodium) that disable vanilla sky rendering.
– **Driver Support:** Compatible with both NVIDIA and AMD GPUs (OpenGL 3.0+).

## 🎛️ Configuration

While the default is Green, the pack is fully configurable via the **Shader Options** menu in-game.

### RGB Color Channels
You can manually mix the phosphor color using 0-255 sliders.
– **Classic Amber:** R: 255, G: 176, B: 0
– **Macintosh White:** R: 229, G: 251, B: 255
– **Neon Purple:** R: 214, G: 3, B: 220

### World Settings
– **Contrast Threshold:** Controls the sensitivity of the edge detector (higher = darker world, lower = more noise).
– **Void Distance:** Sets the strict cutoff distance where the grid fades into black.
– **CRT Effects:** Sliders to adjust or disable Curvature, Scanline Intensity, and Aberration.

## ⚠️ Known Issues & Troubleshooting

### The “Hall of Mirrors” (Smearing) Effect
If you see the screen “smearing” or trails following your movement, your Depth Buffer is not being cleared correctly.
– **The Cause:** This usually happens with high-performance custom clients or mods that disable the vanilla sky rendering to save FPS. Without the sky pass, the command to clear the previous frame’s depth data is never sent.
– **The Fix:**
1. Ensure **Sky Rendering** is enabled in your client settings.
2. If you are a developer using a custom rendering engine, ensure the depth buffer bit is cleared at the start of the frame.

### Items appear as “Blobs” or lack detail
If hand items look like solid blocks of color:
– Adjust the **Contrast Threshold** in the shader options.
– Lowering the threshold will make the detector more sensitive to smaller depth changes, revealing more detail on close-up objects.

## 📥 Installation

1. Download the `.zip` file.
2. Place it into your `.minecraft/shaderpacks` folder.
3. Launch the game using **Iris** or **OptiFine**.
4. Select **CRT Monochrome Shaderpack** from the Shader list.

*Note: For the best experience, ensure “Render Regions” is enabled if using OptiFine.*
