Blender export after editing nodes problem

[Maku]

Took myself together and started discoveryng Blender again. I imported zeta .truck file to edit some nodes, for example i did small axle lifting just for testing and see if Blender export works (had lot's of problems with it in the past) And what happent next is on the screen. It seems im using wrong settings or something for export, im not quite sure. Just in case i'll add console log and blender screens.

The red faces are the submesh. Open your .truck file and search for submesh and remove the textcoords line

submesh
texcoords

Thanks, it works. But theres also a second problem, when i enter the car, game screen goes black and basicly crashes, is it possible that edited nodes cause some sort of conflict or it doesnt work the way i did, simply selecting nodes and draging them a bit ?

E: I noticed that exported truck file doesnt have lines like this:
;r mirror
submesh
cab

But unmodifed truckfile still has them, so it means i have to put those lines back manuali ?

Keep in mind that beam group are canceled when you export. Probably it deleted the set beam default...
You can just try to copy the new node location into the original truck file if you just moved the nodes so that beams aren't modified

I tought so.

Thanks for your help

E: Now the car explodes. And about truck file, for example i'll take random line :
Original line looks like this : 130, 1.89, 1.37, 0.65, l 1.7

Exported line looks like this : 130, 1.890000, 1.370000, 0.650000, n

Do i need to delete those 0's ? And end of the line there is ''n'' after exporting, should i keep the ending like original file has ''l 1.7'' ?

I'll put screen, guz mayby im doing something wrong in Blender, but basicly what i did i just selected whole axle nodes and draged it a bit down, and then exported.

E 2: Changed node options, and car works now, still something is a bit messy and also few lines are wird:
137,
143,
149,
151,
153,
154,
155,

And they might cause this weird thing with two wheels ?
