Hi Dave,

I am at work so I can't test it right now, but just reading through that
file it looks like you do have coincident surfaces going on with the base
of the cone and the plane. The cone has its base at <0, 0, 0> which is then
translated to <-8, -1, 17>, while the plane is defined at y = -1.

Either move the cone up a small amount:
cone
{
  <0,0,0>, 5.5, <0,11,0>, 0
  translate <-8, -1, 17>
  translate 0.01*y /* add this line to move the cone up from the plane */
  texture {
    ...
  }
  ...
}

Or move the plane down:
plane
{
  y, -1
  texture
  {
    ...
  }
  translate -0.01*y /* add this line to move the plane down from the cone */
}


I will have a closer look when I get home, but I think this might be it?
