I thought I already posted this message. I'll try again. I tried doing what you said, I changed the material to "Object Top" (which really messed up the appearance of the water), moved the material along the X axis using three keyframes (-90 units, 0 units, 90 units), and when I rendered it, the water stood still for a moment, then moved erratically along an axis which was definately not the one I wanted it to move along. Needless to say, it STILL isn't working. I hope there's a way to solve this problem, because it doesn't look like there is. Akril
