Lines, UV Mapping doubts.

Hi c-sanchez
You can put this kind of question in the Interface & Usage session. (I'm going to move it to there later )

That's something you will always notice when you use n-gons and see it in an OpenGL viewer.
If you will not smooth it or will render it in a proper application for that you probably will notice this effect is less perceptible, but you would get better result making the edges hard.

Try and see the result.

Anyway a would suggest you to avoid n-gons.
