Train Cars are Flipping....Help

[Mr Maison]

I'm making my first train and tested it a couple of times in the game. When the train gets closer to view, the cars begin to do somersaults. If I zoom out far enough, the LOD is on the tracks just fine. Anyone know why this would happen? I thought I saw a post about this somewhere but forgot.

FYI, I did make a LOD that have 134 tris, and the main model is a bit high at around 2,400. I couldn't go lower for this model. I really tried. For the test I used a solid light grey color for the both model and LOD so it's not UV mapped yet.

I haven't made a train before, but I know with the car models, the wheels can't be connected to the main car body. Plus, the wheels are the only part that touches the ground plain. That's how the game knows what part to rotate as the wheels. Maybe it's similar with train cars as well.
If the wheels are connected to the main car body, it will do the flips like your train cars are doing.

I was actually fixing that as you were writing your post. Thank you. That's exactly what the problem was.

I feel really bad as the info is right in the Wiki http://www.skylineswiki.com/Asset_Editor . Wheels have to be detached from the rest of the body. The game engine recognizes whatever makes contact with the ground to be a wheel so it will rotate. If your wheels are attached to the body, the whole vehicle will rotate.

I had the wheels attached to everything else following the one solid model rule but missed this detail about vehicles.
