I am just starting to use Vue 6 Infinite and this is really the first 3d program that I have used. What I need to do is create an iceberg that is in a shape that kind of looks like  a tooth. I have a couple of tutorial on creating icebergs, and I know how to edit a terrain with the terrain editor, but I did not see how I could actually change the overall shape to make it more tooth like? is it possible to do something like this? Or if I had some one make me a tooth shape model in Maya, could I import that shape as a terrain? I am kind of under the gun to create this image and I have only about a week to figure out how to do this, so any advice would be appreciated. One last thing, I want to create this image so that you can see half of the iceberg under water and the other half above the water. What would be the best way of going about getting this look?
