Sorry BB, but wood, and special finished wood is something I have to deal with in real life. And there all kind of finishing: beewax, oil, satin gloss lacquer, high gloss lacquer and so on. Perhaps it was some pavlov reaction that I replied, because you made a one solution statement. It was not ment as critic.

 I think that making a wood shader, is just like making a car-paint shader, there is not one solution, but there are many, because there are so many kinds of wood and with all different kind of finishing. A really high gloss wood shader is in my opinion, very difficult to make, because in real life it has about 10 layers of polished lacquer.

Everything I have seen on procedural, one node, wood shaders, especially poser, sucks. So you have to use a good photo as texture and a procedural shader for the finishing. IMHO, one can use a diffuse or clay shader with a blinn shader for oiled, beewaxed or satin-gloss wood because it doesn't have any reflections or highlights. A glossy shader for medium-gloss wood. But for high gloss wood you will indeed need a fresnell shader, as you stated, but I also think you need a kind of sss shader, because the layer of lacquer acts like a thin sheet of glass on the surface of the wood, just like some kinds of carpaints.

best regards,

Bopper.
