Lines, UV Mapping doubts.

[c-sanchez]

I'm practicing with the texturing, UV Mapping, although I seemed simple at first, I see some complicated things, or do not quite understand yet.

to explain to me better I'll will use an example with this "table"

A basic, simple, model


the problem(?) with smooth shading

why this happens?

on Ultimate Unwrap3D (3ds exported from Wings3D)

As far as I can assume, these lines should NOT appear.
the "squares" on top are simple extrudes.

As always, thank you very much for the help.

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.

Try highlighting your object and in RMB menu choose Auto Smooth

c-sanchez, just in case you are lazy to try the approaches. (my turn, )
- The left column your probable initial mesh;
- The middle column the presented mesh;
- The right one is your mesh with hard edges set (easy way is use Auto Smooth as suggested by Radi).
The rows are flat shader; smooth shader using One light; smooth shader using Two lights;

Yeah, the edges hard or auto smooth option are good
Thank you very much for the replies guys, and i'm sorry for my delay in respond.

Heh sorry, Sometimes I have no idea what category to post topics.
