This program has probably been discussed before but I haven't
found any information on it. The basic problem is that when I have an
object with both a normal applied and reflection turned on I get
strange, ugly artifacts. Well, I'll include the source so you can see
for yourself. I'm using v3.02 for Win 95.

#include "colors.inc"

#declare theta=2*pi*clock

camera{
 location 3
 look_at 0
}

light_source{
 <5*sin(theta),5,5*cos(theta)>
 color White
 spotlight
 radius 15
 falloff 70
 tightness 50
 point_at 0
}

sphere{
 0,1
 texture{
  pigment{color Yellow}
  finish{
   reflection 1
   specular.8
   roughness .006
  }
  normal{
   bumps .6
   scale .3
  }
 }
}

plane{
 y,-1
 texture{
  pigment{
   checker color Red, color Blue
  }
 }
}
