After I mapped the texture of an object, some of the faces seem that does not have a correct texture mapping like the following image. I have tried to recalculate the normals but it does not help. Why? How to fix it?
When I select a face with texture mapped correctly, the area with texture background also displayed in the UV/Image Editor.
While when I select the face with texture mapped incorrectly, the UV/Image Editor cannot shows me the texture background.
