    First of all, I will say that I am not a modeler by any means, and I don't understand the lingo used.

    I hear a lot of people of this forum talk about UVing a model. What does that mean? Is it like and ultraviolet light baking kind of thing, or is it something completely different than that?

    Also, why is UVing a model important to the final product? What's the difference between an object that has been UVed and one that hasn't?

    Sorry if this is kinda a stupid question, I just want to know what it means so that I can vaugly follow progress of certain mods and official vehicles and so on.

    Put simply. UV'ing a mesh actually determines which bits of a texture file appear where on a mesh.

    Ok, one more question then.

    Why does it take so long? Do you have to input the coordinates for each texture manually?

    Just a bit of a fine art to get it all lined up and working real nice. Far from a straightforward process.

    Ok, so I know SixSixSevenSeven, kinda stated what this is, I figured I could add a few pictures to the explanation since I had them laying around on my hard drive.

    UV mapping is basically the process of making the 3D mesh into a 2 dimensional plan so that you can easily add textures to the different parts. The object shown is a cab for a truck, and is modeled with tris, the first picture shows all of the object in 3d, while the second shows where they are mapped. Simple mapping doesn't really take a whole lot of time, but to achieve a decent, easily modifiable image can become difficult as the poly count increases.
    The object:

    Where they are mapped:

    Hope this might help a bit more. :)
