# Continuum RT

This a fully Ray Traced/Path Traced Minecraft shaderpack. It is intended for high end machines and features many cutting edge graphical techniques. It is also currently in Early Alpha.

## Planned Features
- Fully Path Traced Lighting (AO, GI, Reflections, Shadows, etc.)
- PBR Material Support (POM, PBR Specular, PBR Diffuse) 
- PBR Photometric Lighting System (PBR HDR Lighting) 
- PBR Camera System (Exposure, Grain, Motion Blur, DoF) 
- ACES Color Grading with configurable LMT
- PBR Volumetrics (Clouds, VL, Water Fog) 
- Volumetric Clouds with proper Aerial Perspective Atmospheric Scattering
- Dynamic Weather and Wind Systems
- High Quality and Highly Configurable TAA (Temporal Anti-Aliasing)

## Requirements
- High-end hardware (Nvidia GPU's are preferred at this time, AMD support may be lacking or nonexistant, and Intel HD is not officially supported at all at this time. Hardware compatibility may change as development progresses. Current reccomended specs can be found on our site.
- Minecraft 1.14.4
- **Optifine HD U F5** or **later**. Make sure you have the latest Optifine before you complain about anything. You can get them [here](https://optifine.net/downloads).
- A relatively new Nvidia driver version (if you're using Nvidia GPU), you can find the latest [here](https://www.geforce.com/drivers). This has not been tested with AMD much, but getting a somewhat new AMD driver might be a good idea as well. 

## Installation
- Watch [this video by FernFox](https://youtu.be/t5QFNc9rhNc), using RT in place of 2.0.4.

## FAQ
- If the shader does not function correctly (shows a black or white screen, doesn't work, etc), make sure you are adhering to the requirements; not using Intel HD Graphics, and using the proper Optifine version(s).
- Please do not report this or other missing features as bugs. We are well aware of them and are working to implement them.
- Do NOT set the Shadow Quality setting in video options > shaders to anything but 1x. RT needs it to be at 1x to properly function.

## Known Issues/Bugs
- Entities and noncubic blocks (stairs, slabs, grass, etc.) render and are affected by lighting, but cannot affect lighting/cast shadows.
- Visual noise can still be extreme in some circumstances. Denoising/filtering is still being worked on.
- Some autocam issues when looking at objects that have near/pure black.
- Water looks like Vanilla MC water but with some odd shading.
- No Nether/End support.
- Slight issues with light ghosting and ghosting effects on edges of screen. These are related to reprojection/filtering and are also being worked on.
- Poor/no AMD GPU compatibility. Testing for this will likely occur near the end of Alpha or in Beta. 

## Rules  
- This shader costs money, don't share it.
