I could write a book about this, but to make it short, what most users of a 3D system like Blender want when they get to the shading/rendering part of their work is to simply: - pick an object in the scene - pick a pre-made rich and complicated shader (wood, glass, tar, etc...) from a huge library of shaders expressed in a standard form (as in: that will work with whichever render, be it cycles, luxrender, moonray, etc...) - drop it to the object without having to screw around for hours with texture scaling, rotation, uvs - rinse and repeat until all objects in the scene are shaded Very few people have the skills/knowledge and patience to put their own shaders together themselves by assembling basic nodes into a large and complicated shader tree. There has been some (feeble) attempts to build standard libraries of Shaders around Blender: https://github.com/LuxCoreRender/LoL https://github.com/LuxCoreRender/LoL https://www.youtube.com/watch?v=mCShkpW1c2w https://www.youtube.com/watch?v=mCShkpW1c2w These are: - hard to use - not always free - not standard and portable across renders In practice, assigning materials to a large scene in Blender is still a giant, time-consuming PITA.
