Atmospheric Shaders – NEW LOGO

[](https://kcbhosting.com/aff/Gaboouu)

# Atmospheric Shaders

Atmospheric Shaders is a shader pack focused on sky rendering and lighting.
It is designed to work with SimpleClouds and keeps visuals close to vanilla while improving atmosphere behavior.

## What it changes

### Sky and lighting

The sky uses smoother gradients and better horizon blending.
Light diffusion and sky color transition more gradually across the day.

### SimpleClouds integration

Clouds react to time of day and lighting conditions.
They are visually blended into the sky instead of appearing as a separate layer.

### Weather awareness

Sky brightness and color shift based on weather and biome context.
Storms and clear weather produce different ambient tones.

### Visual style

Colors are kept balanced.
Bloom and post effects are limited to keep the image readable and stable.

### Day and night transitions

Dawn and dusk transitions are smoother with more natural color shifts.

### Performance

Effects are conservative and lightweight.
The pack is intended to remain stable and usable on a wide range of systems.

## Planned changes

Cloud visuals will be refined further.
Water and fog behavior will be improved.
Sky scattering and sun coloration will be adjusted.
Some visuals may later react to weather data such as storms or humidity.

## SimpleClouds compatibility notice

If you are using this with SimpleClouds, be aware that there are many incompatibilities.

Before going to the comments saying that this mod does nothing, read this.

Mods like Alexs Caves, Immersive Engineering, Distant Horizons and others break the fragile balance of the rendering pipeline.
This results in depth and scene composition issues.

I have been working on a fix for a long time but have not found a proper solution yet.

If you are comfortable with GLSL or Java and think you might have an idea, feel free to help.

ASCII Shader

## ASCII Shader intends to make Minecraft render only with ASCII characters!
Current features include:

– Color Customisation for, background, dark, and light colors
– Using the in world colors as the text color
– Post proccesing effects like bloom, sharpness, and tonemapping
– Line detection including multiple line detecting modes and performance settings
– Premade color profiles

There is maybe something I want to add to the customizability this (for now at least) should be enough!

If you find any bugs or incompatibilities, you can always report them, it helps me and others out.


### 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 ASCII Shader and put it in the shaderpacks folder.
Get back in the game, and choose ASCII_Shader in the shaderpacks menu. (Refresh the menu if it doesn’t appear)

Arc

A shader for Iris & Optifine that aims to providing realistic visuals with very minimal performance loss. Almost every effect/feature can be fine-tuned for the ideal balance between performance and quality. This project is still in beta but will be reaching initial release very soon!
 
### Features
– HDR
– Full PBR support
– Dynamic, direct, colored block lighting
– Volumetric fog/lighting
– Automatic exposure
– Screen-space reflections
– Water waves & refraction
– Supports distorted and cascaded shadow mapping.
– Depth-of-Field
– Bloom

Also contains special support for [PhysicsMod](https://www.curseforge.com/minecraft/mc-mods/physics-mod) ocean waves & snow!

### Resource Packs
Supports LabPBR and OldPBR texture formats; The default setting for materials is “vanilla”, which hard-codes a limited set of PBR material values for the original Minecraft textures.

The recommended resource pack is [Patrix](https://www.patreon.com/patrix); when used make sure to set the shader setting for Material Format to “Patrix”, as it uses a special combination of OldPBR and LabPBR formats.

### Compatibility & Support
For best results use Iris 1.6 or later; however most features should work with Optifine or Oculus. If you have any suggestions or requests, you can reach out to me on the [ShaderLabs Discord](https://discord.gg/9CRwrfYU).

## Installation
1. Download the Alpha Piscium shaders for Minecraft from [Modrinth](https://modrinth.com/shader/alpha-piscium) or [GitHub Release](https://github.com/Luna5ama/Alpha-Piscium/releases).
2. Install [Iris](https://www.irisshaders.dev/download) shader loader.
3. Open the Minecraft launcher and choose the Iris profile you just created with the version you’re playing.
4. Launch Minecraft.
5. Go to **Options** → **Video Settings** → **Shader Packs**, then click **Open Shader Pack Folder**.
6. Move the downloaded ZIP file into this folder (`.minecraft/shaderpacks`).
7. In-game, select the newly installed pack from the shaders list. (If you select a shader pack using Iris, its filename will turn yellow.)
8. Click **Done** or **Apply** and the shader will be loaded.

## FAQ
– **No lighting at night**: Please use PBR resource packs. For vanilla style, SPBR is recommended. Otherwise, try Patrix.
– **Can’t load shaderpack**: Please use Iris with version 1.7 or higher.
– **Everything goes dark when turning back**: This is due to the limitations of screenspace techniques. There isn’t a perfect way to fix this.
– **Intel GPU**: Alpha Piscium uses cutting-edge graphics technology. Unfortunately, Intel doesn’t maintain their OpenGL driver well, so Intel GPUs are not supported.
– **AMD GPU**: Check if your GPU driver is newer than 22.7.1. If older, please update your driver.
– **Other loading errors**: Press Ctrl+D in Iris’s shaderpack selection screen, then reload the shaderpack. Make an [issue](https://github.com/Luna5ama/Alpha-Piscium/issues) with the error message and the relevant files in `.minecraft/patched_shaders` as shown in the error message.

Allium Shaders

# Allium Shaders


Allium is an edit of [Complementary Unbound](https://modrinth.com/shader/complementary-unbound) focused on bringing my creative vision to life. Emphasizing the beauty in colors and effects, all while staying as performant as it can be. With Allium, I hope to deliver a unique style and aesthetic that pushes my creativity to it’s limits.

v2.0 has received a massive overhaul on it’s overall look, feel and atmospherics. Even though this shader is fairly young and hasn’t received much updates, I began to feel as if the appearance was not going in a direction that I had originally intended. So I’ve spent the past couple of months revisioning what Allium should be, and what should have been. Although it’s not perfect, I have been fairly happy with how it has turned out and wanted to share it with you all. Cheers! 🙂

### Huge Thanks
– Emin for using [Complementary Unbound](https://modrinth.com/shader/complementary-unbound) as the base shader
– Query for their wonderful LUT code from [MollyVX](https://rutherin.netlify.app/mollyvx.html)
– Xonk for their RTGI and RTAO implementation

### Disclaimer
This shaderpack includes code that was generated or assisted by Artificial Intelligence. While all code has been tested for functionality and performance, users should be aware that parts of the logic (e.g., GLSL functions or noise algorithms) were created with the help of generative AI tools.

Makes your Minecraft world look like it was filmed with an old 2000s camera – nostalgic vibes and retro atmosphere 🙂

I’ve been doing my projects and stuff, but at some point I fell in nostalgia, remembering these days playing with old cameras as a kid and these records with a lot of bloom and noise…
I decided to quickly make a Minecraft shader doing similar thing.

I hope, I’ve done my job!
