If one is doing ray tracing on that, I have heard that all surfaces will
look as though made out of plastic. If one wants surfaces of different
textures, like wood, ceramics, etc., one supposedly needs to have surface
elements that are capable of suitably dispersing the light; reflections
alone should not be enough. Real life objects disperse the lights, which in
its turn is reflected/dispersed onto other objects. This is what make
something look real.
