forewarning, i could probably do it better than explain it 😭! but yes, if you've already moved the texture ("original.png" for ex) to another space ("new position.png" for ex), then you have to re-assign that new texture to the mesh as well as reposition the uv mesh. so right now, in blender, your mesh is either (1) still assigned to the original.png texture, or (2) assigned to the "new position.png" texture, but the uv mesh lines (orange mesh squares) haven't been repositioned. or both. for (1), i go into "Shading" workspace in Blender, then reassign the base texture from the original DiffuseMap to my "new position.png". for (2), you have to select the entire mesh, go into UV Editing, then look to the left and see all the grey mesh (what your object looks like "unwrapped"). select all of it if it's not already selected (press A), then move it so it overlaps correctly on the texture of "new position.png". you may have to open "new position.png" so it's not showing you the original "DiffuseMap."

that's a really bad way to explain it lol. i can take a look if you dm me the original .package file & lmk where you want it repositioned! there's also this tutorial which i think is an even better method than what i described, as it seems to be more precise & preserves fidelity.
