What is the Kappa Shader?

A Minecraft shaderpack that aims towards a realistic, but also authentic look. So it is not plainly using physically accurate vales and equations like many other packs do. Instead, while still using many accurate calculations, it is tweaked to reproduce what you could observe in nature, which usually goes beyond just having equations to describe most phenomenons. A version of this pack with path-traced lighting also exists in the shape of KappaPT.
