Hi,
There is no background, only the fish and the wave which is in front. I guess Im not describing what I want to do. I want to animate the fish jumping out of the water (the transparent bkg) and when it dives back, the wave layer that it over laps will mask it, but the wave is transparent too, so the fish as it dives back into the water, will be partially masked by the wave layer (which is transparent) until the fish disappears. I want to do it this way in case I want to put the animation on a blue bkg or a red one or whatever.
Is that more understandable?
I drew a picture
