Zephyr Starlight

⚠️ Disclaimer: This shaderpack is an early work-in-progress so bugs, missing features and performance issues are to be expected.

## Features

* Accurate ray-geometry intersection
* Path traced diffuse, reflections and sun shadows
* Temporal anti-aliasing and upsampling
* Normal & specular mapping support
* Physically based sky rendering
* Hillaire multi-scattering approximation
* Sparse irradiance cache for diffuse multi-bounce approximation
* Reflection motion vector calculation (no TAA ghosting on reflections)
* Spatiotemporal denoising
* Camera effects: motion blur & depth of field
* Post-processing: auto exposure & chromatic aberration

## Compatibility / Mod Support

* GPUs: NVIDIA, AMD
* Minecraft – version 1.21 and above
* Iris – version 1.8.0 and above
* Optifine – not supported
* Distant Horizons/Voxy – not supported (planned)
* OrthoCamera – supported but still broken in a few cases
* macOS – not supported

## Performance Tips

* Sample count: This directly affects the quality of the lighting. Higher sample counts show less noise and more detailed lighting/reflections at the cost of performance. Keep this at 1 for the best performance.
* Diffuse Lighting > Denoising Passes: The amount of passes used for diffuse lighting denoising. Even though not as high as sample count, this has a performance impact too. You can still get decent lighting with just 6 passes most of the time, but a pass count of 8 is recommended for the best lighting. You can set this to 0 if you’re fine with the noise.
* If you are in a completely closed room with no outdoor light entering it, set Shadow Samples to 0. This will disable sunlight.
* Irradiance Cache > Update Interval: The maximum amount of frames that are allowed to pass between updates of the same part of the irradiance cache. Lower values cost more performance, but result in more responsive lighting and less noise in reflections.

Vulkanite Demo Pack

# Vulkanite Demo Pack

This is a demo shaderpack for https://modrinth.com/mod/vulkanite-mod. It needs an RT capable GPU (10 series and up on Nvidia, 6000 series and up on AMD).

## Warning

This pack is only a demo, meaning it’s not really intended for gameplay purposes, but as a future reference for developers and a technical showcase. Please don’t report issues related to the look of the pack.

You _have to_ use a PBR capable resourcepack, otherwise the shader won’t work properly.

## Features

The following features were implemented

– Path traced lighting with configurable bounce amounts
– Reprojection and Infinite standby accumulation options
– Rudimentary PBR texture support
– (Bad) auto exposure
– Water reflection, refraction and fog support

## Contributions are welcome

VTXS Screen Space Demo

![VTXS](https://cdn.modrinth.com/data/cached_images/c05f89e29f7fe27d7e4917ca90e55d2c8788c43f_0.webp)

The VTXS project was born to challenge the modern graphics trend of smearing everything with TAA and upscaling. The philosophy behind VTXS is that everything stays perfectly sharp, regardless of camera speed.

## Screen Space Demo
This shader introduces a lighting system developed exclusively for VTXS.

Each emissive pixel visible on screen illuminates the scene and casts shadows.
The noise level is low enough for real time gameplay without requiring denoising. However, a denoiser is still present as an optional feature.

While being a demo this shader is intended to be used for gameplay, so all features necessary for a complete and playable experience are planned.

### Implemented Features
– Screen Space Path Tracing
– Physically Based Atmosphere
– Full roughness range specular reflections
– Volumetric clouds
– Godrays
– Subsurface Scattering
– Variable penumbra shadows
– Bloom
– Eye adaptation
– Screen Space Raytraced Refraction
– GBAA Anti-aliasing

Big thanks to [jbritain](https://modrinth.com/user/jbritain) for making vloumetric clouds for VTXS!

It is highly recommended to use a PBR resource pack, as the integrated PBR system is very limited.

The shader now works on Intel GPUs, however, there may still be issues. Please report any issues in my [Discord server](https://discord.gg/5zg5XuhCBk).

VanillaPuddingTart

**This pack uses the vanilla shader system, it’s not compatible with Iris or Optifine!**

**To use the pack you need to enable the _Fabulous!_ graphics mode in the video settings.**

# VanillaPuddingTart

VanillaPuddingTart (an abbreviated and then incorrectly unabbreviated version Vanilla Path Tracing) is a resourcepack that adds global (non-screen space) lighting effects to the game, such as:

– Colored light emitting blocks
– Bounced lighting
– Metals and specular effects
– Realistic sun lighting
– Realistic block shadows

## Using texture packs

The pack comes with a built-in texture pack but if you have the time it’s recommended to use a third party one.

Texture packs need to go through a conversion process to work with VPT, please follow [this guide](https://blog.balintcsala.com/posts/vpt-setup/) if you want to do this. This process is heavily RAM-limited, so packs with large textures might fail (I recommend at most 128x).

## Compatibility

1.) The pack is _incompatible_ with any mods that might change how the game draws stuff, notable examples:

– Optifine
– Sodium
– Rubidium

2.) Because of the nature of vanilla shaders the only supported version is the last major release (e.g. 1.20). The pack may work on older versions but it’s not guaranteed to.

3.) The minimum supported resolution is 1024×768 and the maximum is 3840×2160, going below the minimum or above the maximum in either direction (e.g. 1000×768 or 3840×2500) will cause glitches.

## Known issues

Please don’t report these:

– Water is broken (will be fixed later)
– A handful of blocks don’t have built-in support
– Lava is broken (will be fixed)
– Lava doesn’t emit light (probably can’t be fixed)
– The end and nether doesn’t work (probably can’t be fixed)
– Emissive parts don’t always follow the rotation of the blocks

## Early access

Early access versions are available one month before the public release for patrons.

Ultimate Nausea

I was messing around with shaders and made this. Good luck.

This shader makes objects that are far away appear to spin. This was done by applying the sine and cosine functions to the distance from the camera to each vertex.

WARNING: The larger your game resolution, the less inventory visual bugs there will be!
