Reverie
Reverie is a minecraft shader with a semi-realistic, dreamy style. It features a physically based atmosphere and advanced indirect lighting techniques.
Support for both **Distant Horizons** and **Voxy** is available, with more mods coming in the future.
### Dynamic weather system
Weather elements such as cloud cover, fog, and wind direction adapt dynamically based on biome, season, and altitude. Still, having every location always look the same would feel repetitive. To keep things fresh, these parameters are slightly randomized every time the shader loads, so each day looks unique, much like in the real world!
### Powerful & Customizable
Reverie has a streamlined customization system. Most light colors are customizable (with more to come). If you’re performance constrained, then rest assured. Set the profile to ‘Toaster’ and enjoy good performance (60fps on my laptop’s integrated graphics) with minimal visual compromises.
### Beautiful screenshots
The built-in screenshot mode freezes the weather, so you can get your shots lined up just right! Enable cinematic effects like depth of field, lens flare or chromatic aberration, to get the vibe you want exactly. Reverie also has advanced color balancing options, as well as several tonemappers to choose from.
### Requirements
– Iris 1.8 or higher.
– Minecraft 1.21+ (older versions might work)
### Hardware compatibility
– Nvidia: works
– AMD (windows): works
– Intel (windows): unkown
– Mesa: works
– Mac: broken, and cannot be fixed
### Issue reporting
If you’re running into problems, head over to [GitHub](https://github.com/thecmk/reverie-shader) and report them.

Rethinking Voxels
# Rethinking Voxels
This shader is an edit of [Complementary Reimagined](https://www.complementary.dev/reimagined) that aims to be decently fast (when compared to path tracing shaders) while having block lights cast sharp shadows.
### Notes
The lighting system is not perfect. Occasional sudden brightness changes are a side-effect of the way it works and cannot be completely removed without hurting performance or removing sharp shadows from light sources. To do the latter, disable `Per-Pixel Lighting` in the `Rethinking Voxels Settings`.
This shader is developed on Iris, using an AMD graphics card on linux, and it is also tested on an NVidia graphics card on linux. While it usually works on other platforms, bugs that appear only there are not caught by my testing and hence they take longer to fix. To use this shader pack, the Iris shader loader is required. Beta 18d and older versions also work on OptiFine.
### Contact
If you need support, please join the [shaderLabs discord server](https://discord.gg/8wT5KxF4TZ), where this shader has a channel (#rethinking-voxels-gri573).
### Partnership
I have entered a partnership with Ember, a Minecraft server hosting provider. This is because Ember hosts the complementary SMP server and has provided a better hosting experience / customer support than the previous hosting service, and because they reached out asking about it. If you need to host a Minecraft server and wish to support Rethinking Voxels’ development at the same time, do check them out! Using the promotional code `RETHINKING` in a first-time purchase will redirect 70% of the first month’s fee to me as well as give you a 10% discount.

RenderPearl
# Modern, lightweight shaders for Iris

RenderPearl is an incredibly lightweight shader pack using the latest Iris features and optional extensions on various graphics drivers, aiming to deliver pleasant visuals with excellent performance on modern hardware.
If you want to report a bug or give feedback/suggestions, the best way to do so is by opening an issue on the [GitHub issue tracker](https://github.com/Luracasmus/renderpearl/issues). I rely heavily on user feedback in bug fixing and design.
Trivia
This project started as a continuation of “Luracasmus Shaders” (which is why you might have seen it called “LS RenderPearl”), but modern versions share little to no code with the original project. The question remains as to whether the same shader pack remains throughout, when all parts are replaced.
The name “RenderPearl” is inspired by the Bedrock Edition [RenderDragon](https://minecraft.fandom.com/wiki/RenderDragon) engine.
## Features
LabPBR 1.3 compliance & material data
“Yes” indicates support for per-texel data.
| LabPBR 1.3 required component | From resource pack | Configurable nonstandard channels | Included/procedural |
| —————————– | —————————————– | ——————————— | ———————– |
| Albedo | Yes | No | No |
| Smoothness | Yes, or as linear or perceptual roughness | Yes | Yes |
| f0/reflectance | No | | Constant |
| Normal | Yes | No | Yes |
| LabPBR 1.3 optional component | From resource pack | Included/procedural |
| —————————– | —————————— | ————————————– |
| Hardcoded metal | No | No |
| Porosity | No | No |
| Subsurface scattering | No | Constant, only on translucent geometry |
| Emmissiveness | No | Yes |
| Ambient occlusion | Binary, per-block (from model) | Yes |
| Height | No | No |
* Smooth, colored real-time shadows and volumetric light using distorted shadow mapping.
* Colored block light with physically based reflections using a light list combined with vanilla lighting and average texture color.
* Ray traced, per-hand hand light.
* A wide range of highly optimized post-processing effects, including compute shader implementations of [FidelityFX Contrast Adaptive Sharpening](https://gpuopen.com/fidelityfx-cas/), [SMAA](https://www.iryoku.com/smaa/) 1x from [SMAA-MC](https://modrinth.com/shader/smaa-mc), automatic exposure and a variety of tone mapping operators.
* Customizable waves and water opacity.
* Built-in utility features such as light level visualization and a compass overlay.
## Mod & Resource Pack Compatibility
Most built-in PBR information, including light colors, material normals and roughness, are almost entirely procedurally generated and should therefore work perfectly with most resource packs and mods.
Integration with Distant Horizons and Voxy is supported on the latest Minecraft version, but experimental and very basic. Complete support is planned for a future update.
Support for mods that modify the Iris shader pipeline, such as Chunks Fade In, is experimental and may have issues, such as the shader pack failing to compile.
## Requirements
> If you have a decently modern non-macOS device it probably supports everything you need, but you might have to update your Iris and graphics drivers.
* **Iris** with support for features:
* `BLOCK_EMISSION_ATTRIBUTE`
* `COMPUTE_SHADERS`
* `CUSTOM_IMAGES`
* `ENTITY_TRANSLUCENT`
* `PER_BUFFER_BLENDING`
* `SEPARATE_HARDWARE_SAMPLERS`
* `SSBO`
* **Graphics drivers** with support for **GLSL 4.60.8+**.
* **Minecraft** of a version that is listed as supported by the RenderPearl release. The latest supported version is usually the most stable.
Driver Support
| OS | Drivers | Support |
| ——- | —————– | ——— |
| Linux | Mesa RadeonSI | Perfect |
| Linux | Nvidia | Very Good |
| Linux | Mesa Zink/RADV | Good |
| Linux | Mesa Zink/Nvidia | Unstable |
| Windows | AMD Adrenalin | Good |
| Windows | Nvidia Game Ready | Very Good |
Only the latest stable versions are tested. All other drivers are untested. Please report any issues that occur.
## Tuning & The Compatibility Menu
The default configuration and all values selectable with profiles are intended to work on all systems that meet the shader pack’s **Requirements**, though you may be able to achieve higher performance and quality by changing some of these options. Beware that some values may cause the shader pack to not compile, in which case you simply have to reset the option. These are usually marked with a red ⚠.
Implementation-Limited Options
> The usable values and effects of these options depend on your graphics drivers.
* **Light List Capacity** is limited by the amount of Local Data Share memory usable per work group on your GPU. Depending on your GPU and graphics drivers, and the features enabled by the 16/8-Bit Types option, you may be able to set this significantly higher than the maximum value selectable with profiles (though there is no reason to do so if the light list isn’t being filled completely, usually indicated by lights flickering, as it impacts performance negatively).
* **16/8-Bit Types** uses optional OpenGL/GLSL extension-provided half- and/or quarter-sized data types to reduce register, LDS and VRAM usage. Performance impact varies depending on hardware and drivers, as conversion between types has a cost, but operations with smaller types can be significantly faster.
* **Trinary Min/Max** performs trinary minimum and maximum operations in singular function calls using the optional `AMD_shader_trinary_minmax` OpenGL/GLSL extension, which may allow generation of more optimal instruction sequences. It’s recommended to use this whenever possible.
* **32×16-Bit Multiplication** performs multiplication between 32-bit integers and integers in the 16-bit-representable range using special functions provided by the optional `INTEL_shader_integer_functions` OpenGL/GLSL extension, that may be faster than regular 32-bit multiplication operators. It’s recommended to use this whenever possible.
* **Immutable Constants** marks all shader variables that can be immutable as constant, possibly enabling better optimizations. This feature is required by the GLSL specification, but still unsupported on some graphics drivers. It’s recommended to use it whenever possible.
## Design & Modding RenderPearl
RenderPearl’s source code is intended to be modifiable and re-usable. It’s written according to best practice to the best of my ability, but prioritizing performance over readability. If you have any questions about how it works, feel free to contact me on any platform.
Technical information can be found in [the GitHub repository](https://github.com/Luracasmus/renderpearl/blob/main/DEV.md).

RedHat Shaders
– About
RedHat is a shaderpack that for Iris and Optifine.
It is an edit of an old version of Chocapic13, and has many features.
RedHat’s main features are lighting effects such as Godrays (3D, or 2D, if you have a low-end machine), Shadows, Underwater Light Absorption, and many more.
The shaderpack features reflections too, and reflects some light on all surfaces, to make everything look more similar to the Minecraft trailers style.
There are many cinematic options such as Lens Flares, Depth of Field (Chromatic Aberration included), Grain, Tilt Shift, and others.
The colors, which change depending on the time, make everything more realistic yet they keep the fantasy vibe.
There are many effects related to movement as well. All foliage or hanging things such as lanterns wave. Along those there are Waving Hand and Waving Camera options too, configurable as well.
If that wasn’t enough, RedHat supports all versions from 1.7.10 up to 1.21, and it supports custom skyboxes!
Lastly, there are many atmospherics effects such as Fog and Clouds, Round moon and sun, and other things like PBR support, Auto-Exposure, Stars, and many, many other things.
There are a lot of ways you can customize the shaderpack, and make it look like the way you want.
– Requirements
GPU: Must support OpenGL 3.2 and have at least 1GB of VRAM. AMD, NVIDIA and Intel are all supported (You’ll have to decrease some settings to play smoothly with Intel GPUs).
CPU: Must have a minimum clock speed of 1GHz
RAM: Must have located at least 1.5-2GB of RAM to your game
OS: Windows (7,8, 8.1, 10, 11), Linux (Mesa drivers might lead to issues)
Shadermod: Optifine or Iris
MC Version: 1.7.10, up to 1.21
> Light Settings Recommendation: i3/i5 3-4th Gen, 4GB DDR3 RAM, GT 1030 2GB GDDR5
> Balanced Settings Recommendation: i5/i7 8-9th Gen, 8GB DDR4 RAM, GTX 1050 Ti 4GB GDDR5
> Heavy Settings Recommendation: i5/i7/i9 10th+ Gen, 16GB DDR5 RAM, GTX 1660 Ti 6GB GDDR6
If you use RedHat without meeting these requirements, then keep in mind you’ll take a risk.
RedHat is a pretty heavy shaderpack, thus do not expect it to be FPS friendly on the default settings.

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. ❤️
