car standing on end model problem?

Hi there I am having huge difficulty in setting up a car rig… I know I know explained loads of times before… but here goes:

I have been using the car)tutorial from here:

http://www.gotow.net/andrew/blog/?page_id=78

I can add more cars in fine using the source fbx included in the download. The problem occurs when I import my own models, I have tried to match build structure of the included fbx and I mirror the setup of the colliders, the issue I am having is when I add the player control script and run the file my car flips vertical? I have included a screenshot to hopefully trigger thoughts if people have seen it before.

In the shot I have paused the build so I can capture the action. I have trawled the forum looking for similar and I have also tried moving the box collider to stop the flip but still no luck.

Apologies if this is newb question as I am coming from a flash background with no experience of 3d models or importing etc.

Any help would be wonderful.

Thanks

What 3d program do you use? Max has a z up coord system, Unity is Y up… Also, do you reset scale/rotation before export?

You can make an empty game object, use it as the controller and attach the car to it (but not as good as exporting correctly)

Thanks Jay, I received the models so I will contact the creator in the morning.

Many thanks, that sounds like whats happening.
