The plate is decorated with an image map derived from Steven Abbots' 
Knots3D program.  The left stem is UVmapped bimap, the right stem is 
procedural.

The stems look much better now, but the grapes still have that solid 
look to them.

I agree, the image is great but it doesn't look real.

hi jim,

beautiful work!  just awesome.  the one thing i think that
is a lil off on the grapes is the same thing you run into with
teeth...  they are translucent to a degree.  you can see inside
a bit.  like somebody said, they seem too "solid".

but thats just a tiny issue.  the picture is beautiful as is.

that is a sweet image... when you finish it and have a good composition,
(meaning the "art" of the scene is comeplted as well as the models,
etc.) I'd render a large image and submit it to the galelry of some
print 3d mags.  Expect publication, and MENTION POV! :)

  Really nice. Only the problem about that solid aspect... can't you apply 
some kind of faked subsurface scattering? I think it's the only detail 
missing: perfect for the rest!

Thankyou...
believe it or not, the whole thing began when I wanted to play with the
"subscattering"
code others had posted:

#declare m_red_grape = material {

        #declare Color= rgb <.50,.15,.11>;

        #declare factor= 1.25;
        texture {       //create veining
                        pigment { radial frequency 80 turbulence .25
                                         color_map {
