I'm currently reading Principles of Three-Dimensional Computer Animation by Michael O'Rourke. He has a nice section on lights that I found informative. On the subject of point lights he says, "Unlike a real light bulb, however, a point light does not have any size or any shape. In other words, it has no geometry at all. [sic] You only see the effects the point light has on objects in the scene [sic]. Hierarchically grouping a light becomes espically important if you want to have an actual light-bulb model in your scene. [sic] ...you define a point light to be located at the center of this geometry... [sic] Finally, to make the bulb geometry and the point light stay together, you hierarchically group them." pp. 89-90. I'm guessing that since the point light is not a physical thing, it does not reflect, only real objects reflect. So that is why the method kurzr demonstrated works, the light is put into a real object, which in turn can be reflected. Just a semi-educated guess. jon
