Hi

Glad someone else has the same problem :)
I was reasonably succesful with "blued steel" springs in pov 3.0 and
3.1 but 3.5 won't play. With radiosity they tend to have a red cast,
even using a pigment or reflection with red 0.

You should be able to see the difference here:

sorry)
and stix3v5.jpg, 3.5 and 93k.

For 3.5 I used this which still needs working on
texture{
    pigment{ rgb <0.2,0.5,0.9>*0.8 } // Adjust for radiosity.
    finish {
        brilliance 2
        diffuse 0.2 // Radiosity doesn't like 0
        metallic
        specular 0.5
        roughness 0.05
        conserve_energy
        reflection{ 0.05, 0.3 metallic } // Try <0,0.15,0.3>
    }
}
