Thanks, I already checked that out and your right there is some good info in there but it does not tell you how to change the overall shape of the iceberg, at least not in the way I need to. I would like to be able to create a tooth shape model but then be able to apply a terrain to it so get the look of an iceberg. Also, how can I create a water line so that it looks like we had a camera half in the water and half out?
