Can't you could do it in another way, e.g.


  texture {
    pigment {
      color rgbt <0.8, 0.8, 1.0, clock>
    }

and then run the clock variable in the anima.ini file from 0 to 1 ?



In the case the item has also an IOR, the material would fade away, but the
objects would still refract the light. In your case the light ray from
inside the machine parts. Could look a bit weird.
If so, you DO have to change the interior to e.g.

interior {
 ior 1.5 - 0.5 * (clock > 0)
     //     ===> or whatever the original value was
}
