Texture offset between Painter and Unity

Hello everybody,

Sorry for my english, i am just french and not graphist.

I try to export textures to Unity. When i import the previous exported texture from painter, it don't be aligned on the geometry like on Painter. I see an big offset.

When i export the mesh from painter and use it with Unity, all is good, the texture is in the good place.

I wouldn't like to export mesh objet from painter. I just wan to export texture from Painter.

How can i do this ? Where i am wrong ? It is possible ?

Thx
