I believe I have spotted the issue. I will fix them and re post them.
EDIT:
Yes those piece are just way to long. Even though the normals are facing the right direction for all the polys in the model program, in fact they are getting reversed in GameGuru now.
I cut up that section into 5 pieces and redid the normal direction and they come in fine.
So I will be taking care of all the large pieces the same way.
Also I hate those textures now. So much time to rework those, as they are photograph done. but I need to up the quality in that or they will be obsolete. I have a whole new road system I have been working on, but those were going to be intended for the store. Decisions, decisions.
I will post the fixed media soon for the huge pieces.
Thanks for your patients.
