Hey guys!

I want to get a light to Fade in and out, basicaly like those lights on top of a tower or antena,

I try this:

make a poly sphere
color = white
translucent = white
ambient = light
glow = 1.0970

and then set a keys manually to the transparency to make it disappear and appear. But i also use an area light and i need that to fade in and out with the light also.

Is there a way to make this lights oscilate automaically and not by setting the keys manually to fade in and out?

Thanks in advance!!
