TreeCreator Shader is messed up (see picture). Why?

Hello! When I try applying a Nature/TreeCreatorBark shaded material to the tree trunk it sort of renders messed up. I can't figure out why is this. What do I need to set to make it render properly? http://i.imgur.com/liFf29w.jpg?1 I have ambient occlusion, which works fine on the Terrain trees, and the Terrain details, but the TreeCreator trees don't seem to render the texture properly. Please help
