So... I was wondering why in game a firetruck was going crazy. And then I opened it up in zmod and everything was messed up(as seem in picture). In open iv it looks fine. So In game i noticed that the gear doors were the problem they were missing. So i was wondering if anyone knows how to fix this.

It's too high poly for ZModeler to handle. I think import supports maximum of 64k polygons per mesh, otherwise it will look like this truck.

As far as I know, no. I can't find the topic on the ZModeler website anymore, I think Oleg confirmed there's no way.

I think it's dependent of poly per part. There are models that have more than this and are importable

Is zmod export more flexible, or how did this mod even get made?

As I said, the limit is per mesh, not for the whole model. I can't remember it exactly, but as far as I do, it was something around 64k, either polygons or vertices.

Yes. In my experience, export and z3d files worked absolutely fine, just not the import. It's highly recommended not to use such high poly cars ingame anyway, you'll likely get problems.
