Cheers Klaus! Gonna have to look into that, HLSL is as fine for me as Cg or GLSL 
Now that is kinda weird 
Most likely not since UE4 is all deferred, but that’s cool.
BTW I did find the Shader Dev page by now… still reads strangely cryptic to me right now but probably a matter of getting into “the UE4 way” of thinking…
Also noticed something built-into the sample projects called a “Skylight” but impossible to tell if that only works as pre-baked lighting or also dynamically (if so, how, as spherical harmonics or what…) it’s all a bit black-boxy right now for me
