Best way to edit texture UV in Nifskope?

[Mud]

I've been working on a little project using InsanitySorrow's collectible cards resources, and to do what I want I need to alter the card meshes' UV maps to fit my own textures. The textures used for my cards take up a space of 819x1024 in a 1024x1024 texture file, and being cards I want to ensure the UV maps match the corners of the cards as best as possible. What's the best way to do this? I know I can meticulously try to translate the UV map's points to where I want them to be, but that seems slow and not as accurate as it could be.

You could use 3ds or Blender and create a new UV map.
Or in Nifskope -> Right click on the mesh -> Texture -> Eport Texture.
Then you have a UV in TGA format.

Alternatively, Nifskope UV Editor can also be used.

However, the zoom factor is bad and you should only correct real details in the UV editor.
