Alright, I'm working on another new truck and I've run into a problem. I've got all the model work done and I loaded it in game to test it out and two of the faces on the right (passenger) bedside are missing in-game. I took a picture of the wireframe in Bin-Edit and Highlighted the missing faces in red. The red areas are two ditterent faces. The other lines inside them are from other faces.
I was wanting to know if there was any way to fix it without having to re-do the model (Rep-Fan's 1988 Cheyenne, by the way)
P.S. I'm having the same problem with the Problem Child truck though there is another face missing on the other side as well.
