two faces on the same plane!

[Melssj5]

How can I solve this:

when two faces of objects are exactly at the same plane it generates a crossing texture showing efect or something like that. I mean that sometimes you se one, sometimes you see another, or mixed? can I fix this without remodeling the map making it appear just one of them.

No, there's nothing you can do about this. It's called z-fighting...there's no way around this expect changing the model itself.
