Model exporting

I've done all that, and It's still there. They're both taken from the front, one is just with the camera tilted a bit. If I move the camera down, the gap appears and when I move it back up, it's fine again. I'll see if it's in game too. I'll have to finish the textures first.

Edit: nevermind, I just noticed all the other textures are see-trough. I can see the wall coming trough the upper wooden thingey. Is this normal?

2nd edit: How do I have to call the files? I've tried wall_wall.dds and wall_wall1.dds but modelview gives me an error: failed to create .mat for wall_wall1.dds
