UV Mapping in MDL

Well I know UV Mapping goes in TVertices, and they are positions of faces vertexes on image u & v. But I think faces can't share vertex because then uv mapping would be impossible... so they are cloned then? or don't?
Could someone please clarify?

UV mapping is the position of the *vertices* on a 2d plane instead of 3d space. It's a completely different coordinate set; essentially, every vertex has five coordinate values. The U and V coords are the only values used in UV mapping; the X, Y and Z are using for the vertex's actual position in 3D space.

yes i knew that, but 1 pair of UV per vertex, and vertex is used by two faces, and how do you guess which one face uses that vertex coords... I seen that many times in other games vertex must be cloned...

The faces are connected on the UV plane in the same way they're connected in 3D space.

So you can't have 2 faces using parts of textures far from themselves?

Not if the vertices are welded.

welded? ;/

... Take a step back, try to make some models and get some hands-on experience before you try to understand *how* it does it.

Two or more vertices can be "fused" into one. And of course one vertex can't be in more of one place in the uvmap.
