Uru Rendering Problem

Hey everyone. I'm working on my first Age and I'm using Bryce to make my terrain by following the Bryce terrain tutorial along with the First Age tutorial for the UV mapping and other stuff. However, when I go into Uru to test it, the terrain bleeds through and I can see other parts of the terrain.
I don't know why its doing this. Please help!
Thanks in advance.
