How to fix a car's damage model?

I've had the same issues whith more than one car lately: it looks perfect ingame but, when you crash, weird things happen. The 2 more common are:
1. The driver's body detaches itself with the nosecone
2. The whole cockpit detaches itself with a tyre or suspension. So, instead of a loose wheel bouncing around the track, I get an entire car attached to it, flipping about - not very realistic.

I know it has something to do with the damage model or some zmodeler issue, so my question is: how do I solve these issues?

Thanks in advance

check if your objects (28 objects for lod0) are in alphabetic order.
You can easily do it by open the file.GP4 with GP4 Builder and do the Action/ sort car objects.
of course you have to save your file after this action.

Thanks, Gezere! It worked perfectly!

To answer the first one:

Check the driver's body in GP4 Editor and see if it is assigned as z_cockpit_*(maybe '_insert '

z_cockpit_insert object usually flies off when you crash. What is a solution? You can tide it up with any other objects, but z_cockpit_*.

And don't forget you must have 28 objects in your lod0; carefully detach a small face from any objects and assign it as z_cockpit_insert.

It will be better than what you have then However, I would prefer to keep the body as a separated part because I love modding

I have always used the body driver as the z_cockpit_insert object and when the car crashes, I see the body mapping flying away.I thought it was due to the fact I use lod_0 only because it doesn't happen with all the lods.
I didn't know the problem was link to the z_cockpit_*** objects. I will try to assign the body driver to another car part, next time.
So thank you very much for this explanation! Very useful

I use to put the driver body with the "cockpit" part.

Yes, it is one solution to fix the problem but if you want to keep it as a single object? You have to find another car object to assign the body driver Hmmm maybe to use one of the barge_board and to group the two barge boards in one.

the bargeboards still come off in a crash. something more difficult to break off like engine for example, may be better. Personally I attach it to the cockpit, but it does make it difficult to map around the cockpit area if you wanted to make a change

Right! That's one of the reason I want to keep it as a single object. And sometimes, I use the same body driver for other cars so it saves me time. Otherwise, I have to delete all the faces of the cockpit to isolate the body driver (because often mapped on the same texture than the cockpit so I can't select by materials). But you may be right.: with the engine object, it would be easier and more accurate.
Thank you for the advice

I prefer to keep the driver body as a separate object. I've been playing with the body's position lately and found some really realistic positions for every team. I even have Button's and Hamilton's bodies in different positions, since jenson is taller than lewis...
