Low quality (part of a) texture

[Jernej]

When texturing an object, a blurry low quality patch of texture appears in the middle of an otherwise high quality texture.

The images used are not blurry and the camears are perfectly aligned.
The object itself has about 12 milion poligons. The preset for texturing is in the attachments as well as a picture of the described problem.

This is not the only object i'm currently working on that has this problem.

Any help would be appriciated.

It seems lika a UV problem where the part that is blurry is really small in the UV space compared to its "real" size. At least that is what I assume based on my examination of the mesh UVs
