    Actually, they don't really mean anything. Think of them as coordinates, a bit like how we use X, Y and Z to detail a 3D environment. The letters don't stand for a particular word. Also, there are actually three components to them, which some people omit for simplicity's sake. The full components are actually U, V and W. If you put that alongside the other coordinates you get U, V, W, X, Y, Z.

    Hopefully you get the idea.

    Actually U & V is used when referring to texture maps in order to distinguish them from the X, Y, & Z of mesh geometry (there is no W axis since texture mapping is 2D).

    The W coordinate is used for normalization. While it is indeed a 2D texture map, it's still mapped to a 3-dimensional plane, where the W coordinate is required.

    and after these two have stopped playing, a UV map is the texture template used to produce a texture map. Different figures have different UV maps. They are generated on a 2d Plane, from the 3D geometry, to lay the "skin" out in such a manner as to optimise making the texture map. U denotes one direction and V the other. (or upright and vertical, if you prefer)

    Ahh, yes... I kind of got carried away there. I read the post as 'what does UV stand for' rather than what they actually are.

    Anyway, the reason you've probably heard about people changing UV's is because Genesis can swap UV's unlike most figures. This means that you could use a Generation 4 texture (Such as Victoria 4) on Genesis, simply by changing an option. Because it can swap UV's, it's much more versatile.
