Learning shaders in Ue4

I am currently studying computer graphics and I have already done some very basic shader stuff with OpenGL such as Phong shading, terrain and deferred rendering.

But when I look at some more complicated shaders that the community is making I have absolutely no idea what is going on most of the time.

Any recommendations to get started?

I found a video series for UDK Shaders from Eat3d which I have started to watch. It is probably not 100% the same in Ue4 but I think it should help me to get acquainted with the terminology.

Here are some useful links :wink:

Unreal Engine 4 Documentation | Unreal Engine Documentation -> you will find more such sites when you search in the documentation

Oh wow this is just what I needed Material Expression Reference | Unreal Engine Documentation

I must have missed it.
