Universal PBR Uber-shader

Alexander Samsonov presents a new PBR shader that offers a number of high-end features.

I've created this physically based uber-shader because I wanted to get rid of endless struggle and repetition when creating shaders. So if you ever noticed that you keep messing up with random values to create believable material insted of focusing on more important textures then you'll probably find this shader very useful. Additional 24 presets of various real life materials will give you a quick start up!
