How it works...
From step 1 to step 4 we built the basic shaders, the usual
Diffuse
and
Glossy
nodes mixed by a Fresnel value multiplied by a medium gray color.
From step 5 to step 18 we built the wood veins color, adding three procedurals to be
used as splitting factor for the two wood colors set in the penultimate
Mix
node; by
the last
Multiply
node we made the color more saturated.
From step 19 to step 23 we built the
Bump
node, made by a noise grain summed
to the veins values by the
Add
math node; we set a pretty low value for the
Bump
,
Strength
, but higher values, together with higher
Roughness
values to obtain a less
polished surface, are fine for different kinds of woods.
