Place an object in the level and set this code :-

Code:

---

action metal_object
{
my.metal = on;
my.albedo = 70;
sun_light = 50;
while(1)
  {
   my.pan += 2*time;
   wait(1);
  }
}

---

You should be able to see a sun spot on this object as if its
a metallic object lighted by the sun.Read the manual for more info !
