SEUS (Sonic Ether’s Unbelievable Shaders) Path Tracing Shaders (PTGI HRR 2.1+ E12) is an incredible project to create a shader for minecraft with light ray tracing, this makes the game just incredibly realistic and very colorful, the game will have realistic dynamic shadows, direct sunlight, beautiful reflections and generally physically correct light.
Ray tracing allows you to physically correctly calculate the behavior of light in space, reflection from surfaces also gives its own effects, which makes the lighting extremely realistic and beautiful.
Shaders are being actively developed, but a lot has already been implemented and the game looks just incredibly beautiful, although you will have to pay for such beauty with the power of your video card, and it needs a very productive one.
The shader still has problems, some bugs and glitches when combining light sources, but just look at the screenshots and you will understand everything.
I recommend installing textures and a mod from the same developer
