Uv wrap - wrong

Hello

I’m working on creating 3d models for games (axes, staffs and swords) and found an intriguing problem.

I select the texture normally and it gets right in object mode and Edit mode, when I go to UV edit this appears normal without needing to give unwrap. When I export these templates to the correct extensions and add the texture path the generated file pulls only parts outside the texture tga.

When I give unwrap it plays nonsensical coordinates.
