Exporting a vehicle, makes it go nuts in game

[nnano]

Hey, lately i’ve been noticing really strange thing happening, to be more presice, 3/5 vehicles i worked on, had this problem. When i import a working vehicle, then change one small thing, like delete something or make something smaller, i export the file, launch the game, and vehicles goes crazy, it’s starts floating, if it can even drive, it’ll go only straight, and etc. A video showcasing what’s happening —> https://youtu.be/WFE3vdEsh80?si=YY7jiSorYtiXTUOH it’s like it has it’s own new f7cked up centre of gravity, i guess it’s something with axes maybe??? Honestly no idea, never happened before, but now happened to 3 vehicles

make sure you export both model.yft and model_hi.yft files as their hierarchy (objects set) have to be identical.
If you deleted a part that had a collision, then this part/collision might have been referred from a configuration file.

I advise to reimport model back into zmodeler and take a look - may be some part or collision is in a wrong hierarchy branch?

When i was deleting something, it was purely cosmetic, something that didn’t have a collision, and when i was cheking this truck (that’s shown in the video) all collisions were in their places, hierarchy in .yft and _hi.yft is identical as well

And well for example we take a car that had only pure cosmetic object deleted, it worked fine before, i was changing some things in it a day before (deleting something, adding something, changing UV) and the file wasn’t locked or something. Things like these just started happening out of the blue

What kind of items you have in your hierarchy? You can see that in zmodeler log after export. Limit is 127 and maybe that's why it acts like that.
Do you have licensed Zmodeler? Those cracked versions mostly are fucked up so I hope you're not using one of those.

Of course licensed haha, item limit is not really a possible thing, maybe on truck, but on another vehicle where i deleted 8 items, making the hierarchy item count smaller, it wouldn’t make sense. Honestly i thought maybe problem is with axes, or collision settings, but again, if it worked fine before, and i just changed 1 small thing, what could’ve cause the problems. Could be because of import settings maybe, but again, only 3 out of 5 vehicles acted strangely like this, so wouldn’t make sense. Honestly im confused

the first shot I would to is to import and export with no changes at all.

Fixed the truck, no idea how. Restarted my pc (meaninf restarting zmod as well), imported, checked chassis [COL], reset axes to parent, ungrouped (it was a group), attached the parts togheter, made it a collision part again, exported, now it works. I’ll check other cars a little later.

I do have 1 idea.

I usually leave my pc in deep sleep mode, while zmod is on, so sometimes i dont revalidate my license and keep working with it for several days, maybe it caused that.

may be. the non-licensed version (if something is detected) will make a zero mass vehicle on export.
