I'm stuck. How can you get a underwater scene to show water movement.

have attached two images. One scene and the background seperate.

What do you mean - bubbles? Clouds of silt? Or are you wanting the rippling lines of light from caustics through the waves?

The rippling lines of light... or a cheat effect

Generally it's faked, using soem kind of gel light - a spot light (usually) with a mask so that it shines through only the ripple pattern. There are severals ets like thuis in the store though I think most are 3Delight.

Thanks Richard.

I can only render in 3Delight as laptop has a hissi if I try in Iray.

Look up the word "caustics".

I'm trying to get a decent "ripples" effect working in Iray, but between Athmocam, ocean surface and Gobos, there somehow doesn't seem to be a way to make it work. Plain Athmocam&Gobo works fine, but enter the ocean surface into the picture and all you get is muddy waters...

I'm still experimenting, though.
