I agree that my texturing knowledges still need a lot of improvement...
I took a closer look to Woods.inc,  and realized it was not that easy
to "manipulate"! I think the best way of getting good finishes with woods

is by applying layered textures with filterings... Is it ?!
Thank you for your comments,

As you said, layered textures are often quite difficult to manipulate.  Of
course they have the enormous advantage that you combine the different
layers in various ways to achieve many different effects.  

Turning off reflection should not be a problem though.  

Using nested pigments with pigment maps is often a good alternative to
layered textures.  In megapov you also have things like pigment_pattern
and displace warps that offer even more possibilities.

I will try another shot about this "everythin..." model. I understand the
problem about putting too much reflection on a varnished wood floor...
may be 0.025, not much! (I put 0.22 on my image) ... I thoutht Woods.inc
used nested pigments!

Awesome table.

Many people do not know the sheer possibilities of CSG, but you do need to
know your math.

Well, I don't know much mathematics beyond basic trignometry and 
pythagorean theory, but I can usually eventually cudgel my brain into 
figuring out how to do something in CSG.  For some reason I have a 
pathological aversion to triangle meshes.

One slight niggle I have about the image is that to me, the glasses seem 
slightly out of scale with the table.

Bye for now,
     Jamie.

In fact,  I have to do another rendering about this model.
I have posted the source of the table ( not the floor and the glasses )
on the text_scene_files forum;  you can have a look at this stuff if you 
want.
