Parallax Texture Problem

Just started messing with parallax textures. I made a test file to see how it the different textures worked/look together. However I’m having a very strange issue with floor/ground objects coming appearing in front of everything in player mode. Like I said I’m new to parallax and understand next to nothing about the node tree I’m using. Any pointers or tips would be greatly appreciated. I’ll attach file as soon as possible.

Well, what node tree are you using? Just a screenshot of it will be fine, or upload the blend to an external site. Without it, it’s hard to tell what’s going in.
