Making a Varnished wood Shader

[thinksink]

no one's got info on this?

Well, I don't know any step by step stuff, but... Get a lot of good reference photos, where the wood and the varnish looks the way you want it to look in your render. Keep asking yourself what makes the material look the way it does? How reflective is it? How shiny? How glossy? How bumpy? etc... I guess there are no short cuts, but just good analysis and trial and error. Good luck.

Just set up a slightly reflective shader with some subtle roughness in the bump map :shrug:

The key thing to model is the blend between the wood and the varnish layer on top. Not sure exactly how you'd rig this up but you basically want to use a fresnel with an index of refraction somewhere between 1.5-1.7 to blend between the plain diffuse layer (the wood) and the reflective varnish layer.

If you want to get really complex you could give the varnish layer a very small diffuse component with a yellowish colour that comes in at glancing angles, to model the effect of seeing through a greater amount of varnish.
