Quote - Proper wood shaders depend on the lighting used.  Same with any shader.  Rarely is there a one-shader-fits-all-lit-scenes shader.  The instant you change the angle of a light, the jig is up.

maybe in poser. but not in normal 3D softwares.  

you use a shader and 3 important textures. and it should work in every situation.

 

color (color map)

microdetail (bump + displacement)

reflection map (specular map)
