Hi Sansal,
Confirm last version of Pack3d have a bug. I don't have knowledge for to analyze what is.
I have rework bismark uv and the gun in bottom of ship, have change node position. But with old version, I think the first version of Pack3d, it's fine. Probable this version have other problem but this case no.
This my work

In this site the paint schemes of Ship

Here the problem have the first time, with new version, the last, of Pack3d (but old version, do not export obj with unit multitexture)
Bye and Good Work
