Vshade is a node group collection developed for Blender. Do you think Blender’s shader system is too complicated? Do you think when I want create realistic materials, it is too hard in Blender and this takes me a lot of time? Do you think when I create complicate material, node setup looks like spider web and confusing? Do you think why Blender has not easy setup interface like other render engines, example Vray, Arnold, Corona etc? If you think like these, then Vshade is exactly what you are looking for.
