Weird issue after uv mapping

#1 Post by Raymond7cn » 22 Feb 2023 16:53

Dear Specialists,

I encountered an issue when unwrap uvw of the cabin's model for a truck (ws4900xd) I made recently.

1, I export the cabin part from Blender to FBX, There was no problem with this file that I just tested yesterday.
2, import it to 3ds max, unwrap the uvw map, export the work to FBX again
3, import it to Blender, edit texture as usual, export

Then it looked as these below when entered game:

It's ok from Outside:

You can tell that the exhaust and grill shouldn't be there, they belong to the chassis's locators, I just edited the cabin without touching anything else, Not to mention, it's only being abnormal in Interior view.

Then I checked again and again, export this file for many times, but still to no avail,
They almost have the same size of Blender file

The coordinates of root seems fine as well, However I observed that the pmg file of the one has uvmap has shrunk, whereas I still have no idea what's wrong with that.

The only thing I could think of is the coordinates of cabin or some locators within were messed up after i do the unwrap job, however, I'm pretty sure that I didn't move the model either in Blender or 3ds max, Besides, I don't understand why it's ok in external view but got problem in Interior's view.
I exported this file without unwrapping again, It turned to Normal, But I still have no clue there, I can send this two files to anyone who can help me on this issue, Thanks!

-- There is no error in game.log, BTW.

The hood is also part of the interior model. A separate model to the truck.pmg, so that may be one reason why they're different if you've edited the truck.pmg but not interior/model.pmg
If you suck at playing the trumpet, that's probably why.
