But if the objects are part of other transplated CSGs?

#declare spheres = union{
  sphere{ -2*x, 1 pigment{ rgb<1,0,0>}}
  sphere{0, 1 pigment{rgb <0,1,0>}}
  sphere{ 2*x,1 pigment{ rgb<0,0,1>}}
}
union{
  object{spheres translate 2*z}
  object{spheres}
  object{spheres translate -2*z}
  normal{Norm}
}
