I am working in After Effects CS3, and I need some help.
I have black text (.psd) on a black background, and I would like to create an effect where it looks like the light from a lighthouse sweeps horizontally over the screen, and when it "hits" the text it "appears" as black letters in the light. The best I have manged so far is to put a white text layer behind, use radial blur, and move the center. This however does not resemble the source of the light having a fix point (a lighthouse), instead it looks like the lightsource moves.
Anyone knows how I can do a "lighthouse ray of light"?
