Coat and Sheen Layers
In V-Ray 5, we have implemented a new Coat layer for the V-Ray generic material, which makes it easy to add a shiny polished character to your materials, such as metallic paint, carbon with coating, certain types of plastics, varnished wood, and more. This can significantly speed up your shading workflow, and in addition, get you even faster render results using the Coat parameters, than with traditional workflows such as using a Blend material.
See the Generic Coat and Generic Sheen pages for more information.
