- 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.
