Why is this UV Map face not displaying correctly? Edit 1
Here's the blender file:


Also here's a better image of the face in question

The texture of my model is not displaying correctly onto my mesh.

It revolves around the UV/Image Editor, I'm trying to get that face in the two panels of the first image on the right to show the texture as it does in the image on the left. (note that the image on the left is the right arm of the character and the other two are of left arm)





The dotted face in particular. Not sure if this helps but when I scale that face in the uv map, I've noticed the texture is flipped.
it's becouse your triangle is rotated. Let's i describe it in image:



your vertex number 1 is on position of vertex 3, n.2 on position of 1, n.3 on pos. 2.

so it look like all vertex on right place, but this places are wrong:



Selecting in mesh uv sync mode displays that one vertex is on different positions in UV.
