Alain thank you for your reply. Following your tips I have made something like
that (those are the initial lines from my scene):

#declare Milky =
texture{
    pigment
    {
     rgbft <1, 1, 1, 0.4, 0.5>
    }
    finish
    {
     diffuse 1.5
     ambient 0
     specular 0.2
     phong 0.4
     roughness 0.1
     reflection 0.05
    }}
#declare Texture=texture{Milky}

unfortunately it doesn't work (the elements keep their original texture) Did I
miss something?
