Based on [**Complementary Reimagined**](https://modrinth.com/shader/complementary-reimagined)

Supports Distant Horizons AND PBR!

[WIP] Amethyst Shaders are a modified version on [**Complementary Reimagined**](https://modrinth.com/shader/complementary-reimagined), with quite a few tweaks to suit our visual style. **It is an Official Amethyst Group Project, made by gamerbenyt.**

**Amethyst Shaders** is in a **very Early Alpha state**, and has many bugs. If you encounter any bugs, please [**create a ticket**](https://github.com/gamerbenyt/amethyst-shaders/issues/new) on the **Amethyst Shaders Support Github**.

**Modifications:**
– **Daytime sky is more blue**
– **Clouds have a thick shiny outline to them (does not reflect world outline preferences)**
– **All blocks are more vibrant**
– **The Nether is more contrasty (eg. brighter blue in soul sand valleys)**
– **The End has brighter beams (the fog-type thing) and more stars**
– **The End has a brighter blue-ish-purple sky**
– **Rain adds visible light rays to light-emmiting blocks (eg. nether portal)**
– **Modified pixelated shadows, included in the default profile.**

Our Developers say that they prefer the Reimagined style, as that is what Amethyst Shaders is based on, but there is an option for the Unbound visual style, like normal Complementary.

### Notice:
Though Amethyst Shaders is based on [**Complementary Reimagined**](https://modrinth.com/shader/complementary-reimagined), it **WILL NOT** be getting updates when Reimagined does, and the only updates that will be brought over from [**Complementary Reimagined**](https://modrinth.com/shader/complementary-reimagined), is their updated license, though updates to the license are very rare. We include the Complementary License and follow it, but you must also agree to [**Our License**](https://github.com/gamerbenyt/Amethyst/blob/main/LICENSE)

### Don’t give us the credit!
**Amethyst Shaders is based on [Complementary Reimagined](https://modrinth.com/shader/complementary-reimagined), and we have only modified it to our liking! Go support the [Complementary Team](https://www.patreon.com/emingt)!**

## Amethyst Shaders 2.3 Out Now!

## Compatibility
Amethyst Shaders was build and playtesting using [**Iris**](https://modrinth.com/mod/iris) but should have some compatibility with [**Optifine**](https://optifine.net/home), as [**Complementary Reimagined**](https://modrinth.com/shader/complementary-reimagined) works on [**Optifine**](https://optifine.net/home). We cannot guarantee that all features will be functional, or function correctly on [**Optifine**](https://optifine.net/home), but most people use [**Iris**](https://modrinth.com/mod/iris) nowadays anyways, so it should be no problem.

Aeon

# AEON

Minecraft shaders intended to emulate the graphic design style of early tech, as well as that of certain retro sci-fi, dithered, and other minimalist styles.

Massive thanks to Alex Charlton for their webpage on “Dithering on The GPU”. The code from there is the backbone of this shader.

Adaptive Outline

### This is a vanilla shader with a stroke.
The stroke brightens the light areas and darkens the dark areas.

Remaster by TwentySeven

Thank you for using my shaders! The base shaders are a heavily modified [https://modrinth.com/shader/base-shader](https://modrinth.com/shader/base-shader) to be basically exactly like acid shaders!

I just thought adding my own functions and making the editing process easy would
be a nice little upgrade. I have loved acid shaders since 2016, and have always wanted to learn how to make something similar.

5 years later (2021), I actualy looked inside the shader, and realized it was way easier than I thought it was.
I tried to make something, but never got far with it.

But now, (Late 2024), I actually know what I am doing. I know GLSL, I know how to utilize a workflow, I know what I have to do.
I have to make Acid Shaders fully user friendly.

So I did! just edit the common.glsl file, there’s more information there.

(Note at 9/19/52) Thank you Yahiamice for trying out my shader, I kinda wish you check out the shader settings though, but I’m glad my goal of causing motion sickness succeeded anyways!!!!!11!1!1

Aberration

Aberration is a shader that focuses on the PvP aspect rather than visuals. Most shaders target cinematics, but I wanted to make something that fits the extremely fast paced pvp style (especially crystal pvp).

The shader is designed to work with my own texture pack, “Neon End Crystals,” but it also works with vanilla and most other standard texture packs.

It has a neon theme, giving end crystals unique textures and animations, resulting in really cool effects! It also gives you the option to enable custom arrow effects, such as the Void Halo and more…It does all this whilst having virtually no impact on FPS.

Notice: Please dont use this if you have specific eye conditions or are reactive to flashing lights.

2KS

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!
