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 {
[0.00 rgb Color/1 ]
[0.07 rgb Color/1 ]
[0.08 rgb Clear ]
[0.92 rgb Clear ]
[0.93 rgb Color/1 ]
[1.00 rgb Color/1 ]
}
}
finish { specular .05
diffuse .7
roughness .02
reflection 0
}
}
texture { //create darkening toward the end of grape
pigment { gradient y scale 14
color_map {
[0.0 rgb <.30,.1,.85>*Color transmit .10 ]
[1.0 rgb <.30,.2,.65>*Color transmit .70 ]
}
translate y*7
}
finish { specular .05
diffuse .7
roughness .02
reflection 0
}
}
texture { //bloom on skin of grape
pigment { dents scale 1.5 rotate 10 pigment_map {
[ 0 rgb Clear ]
[ .10 rgb Clear ]
[ .49 LightBlue transmit .97 ]
[ .51 LightBlue transmit .97 ]
[ .90 rgb Clear ][ 1 rgb Clear ] } }
finish { specular .05
diffuse .7
roughness .2
reflection 0
}
}
texture { //bloom on skin of grape
pigment { dents scale 1 pigment_map {
[ 0 rgb Clear ]
[ .10 rgb Clear ]
[ .49 LightBlue transmit .97 ]
[ .51 LightBlue transmit .97 ]
[ .90 rgb Clear ][ 1 rgb Clear ] } }
finish { specular .05
diffuse .7
roughness .2
reflection 0
}
}
texture { //bloom on skin
pigment { dents scale .5 pigment_map {
[ 0 rgb Clear ]
[ .10 rgb Clear ]
[ .5 LightBlue transmit .99 ]
[ .90 rgb Clear ][ 1 rgb Clear ] } }
finish { specular .05
diffuse .7
roughness .2
reflection 0
}
}
interior {
media {
//scattering { 1, (1-Color)*factor extinction
1/factor }
scattering { 1, Color*factor extinction 1/factor }
absorption rgb (1-Color)*factor
emission Color*factor
intervals 1
samples 5
method 3
}
}
}

Thing is, fake grapes often fool me.

There is for me a slightly metallic cast to them. Maybe it's the color
saturation is not quite enough. Tweaking is tedius because this scene
constantly crashes my system.

Thanks for your compliments. Yes the transparency is tricky to pull off.

Maybe brighter lighting that can show off the grapes transparency and 3S
would help?

Maybe some (stronger?) backlighting to bring the translucency out?

I actually like the not-so-realistic presentation. This looks like an still
life oil painting. Very nice!
