I tweaked it some more and finally got this:
isosurface {
function { f_rounded_box(x,y,z,0,0.85,0.85,0.85) - f_noise3d(x*5, y*5,
z*5)* 0.05 }
contained_by { box { -1 , 1} }
max_gradient 25
pigment {
gradient y
color_map {
[0.00 color Gray90]
[0.20 color Gray30]
[0.40 color Gray80]
[0.60 color Gray20]
[0.80 color Gray10]
[1.00 color Gray80]
}
turbulence 0.75
scale <1,0.1,1>
}
finish {ambient 0.4}
scale <0.3,0.1,0.3>
}
That was the look I was trying to achieve. Thanks for your help!
