What is the Kappa Shader?

A 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.

Where can I download it?

Either here or via my website (link below).
