Hi Tim,

IMHO the suggested color is too coarse (is this the right word?). It needs to be
more blotchy. My suggestion is:


#declare Pearl_Light_Gray=
texture{
pigment{
bozo
    color_map {
        [0.2 rgb <0.55, 0.55, 0.57>]
        [0.5 rgb <0.6, 0.6, 0.62>]


    }
scale 10
}
finish{
metallic
    ambient 0.6
    diffuse 0.5
    brilliance 3
    reflection 0.05
    phong 7
    phong_size 20
}
}

The "bozo" makes it blotchy - if it looks very strange try changing the "scale".
I rendered a small model with this color and I'm quite satisfied:

I hope that helps.
Leg Godt-
Sven

(...) Hi Sven, Thank you very much it looks very accurate. I think it's a great improvement and I'll add it to my colour definitions. Tim (18 years ago, 20-Jan-06, to lugnet.cad.ray)

Hi all, I was wondering if anyone had a get texture defnition for pearl grey (like the 1x2 bricks with grilles in the Santa Fe cars). It seems to have quite different properties to other Lego colours. Thanks for any help, Tim (18 years ago, 18-Jan-06, to lugnet.cad.ray)
