Hello.

I'm trying to animate a light to show it off then on by have a blue sphere made of glass with a light in it.  For the first 25 frames the light is on then the next 25 frames the light is off.  However, when I render the small animation the light does not show to go off and on.  This approach has worked for me in moving objects but this time I an not moving something I am only changing a property of it.  How do you animate the changing of a vue object property that has nothing to do with movement?
