Could someone please post a short POV file that demonstrates UV mapping on a
mesh?  The MegaPOV Help file does not give a real good description of
exactly how to work it.

Do the UV coordinates range from <0,0> to <1,1> like they do in OpenGL?
Where <0,0> is the Upper left of image and <1,1> is the lower right?

There's one here :

AFAIK yes (but I could be wrong).

It looks a little more complicated than that. Some images work like that and for
some others it's the opposite on the v axis. I'm quite ignorant about this
because whenever there's a problem I just scale <1,-1,1> the image.

  I think that those coordinates just take the texture at the same
x-y-coordinates. So <0,0> takes the texture at <0,0,0> and <1,1> takes the
texture at <1,1,0>. I think you can also go further, so that <10,20> takes
the texture at <10,20,0>.
  If you are using an image map as texture, it will (by default) range from
<0,0,0> to <1,1,0>, so in UV-coordinates from <0,0> to <1,1>.
  So the answer is yes and no.
