big_hoovie: Tried that before - nogo.(works better if the cylinder tracks the camera - then you can use the camera controls.) I think the light effect IS angle dependent. metaballs? no gotem.(3.1). interesting effect. From your description,"...sunk the camera into the positive metaball...", you used the positive metaball as a lens - whether you want to call it a lens or not is up to you. A good effect either way. gotta go. "kink of the hill" is on and I have to go shoot the TV, hit mute or change the channel.
