Hi Kenmo, 

Apologies, didn't mean to frustrate you. 

Well, adding materials in Carrara is just like in C4D and Vue - drag and drop onto your object. Carrara a la it's precursor, Ray Dream, was one of the first programs to have drag and drop functionality of shaders - Poser was in the same family back then. 

We do have many user based tutorials as threads in this forum that can be tracked down with a search. But they are specific to a certain need, like creating a stone texture on an open box.

If you are trying to build a specific shader, please let us know what it is. Shader design can be one of the most complex things to learn in Carrara, not because it's hard, but because it's so versatile. 

Many folks here are well suited to help solve problems and questions (for free by the way, myself included) but mega-general requests are tough to do because there is no target, not end result. 

In fact, I barely scratch the surface of shader design in my series and it's about four hours long. If you're looking for a complete start to finish tutorial series on how to use Carrara that is free, I'm not aware of one.
