Ok, I've been playing around with Steve Cox' UVMapper and I think I've
got the hang of it, but I still can't get the textures to render
correctly in POV.  I use obj2pov to convert the object file to a POV
mesh.  Do I need a different program to do this or is there something
I'm doing wrong?  I open the obj file in notepad and insert the comment
that tells obj2pov to look for an image map and it doesn't complain to
me, but when I use the image map in POV, it's all distorted again, even
if I use uv_mapping.

There is a glitch somewhere, but the solution is to reverse the image map
by putting it upside down. I guess that scale <1,-1,1> put in the texture
statement should do the trick, or you can just reverse it in a image
editor.

  Does it convert the uv-mapping as well?
  I think you should use 3DS2Pov:

-- 
main(i,_){for(_?--i,main(i+2,"FhhQHFIJD|FQTITFN]zRFHhhTBFHhhTBFysdB"[i]
):5;i&&_>1;printf("%s",_-70?_&1?"[]":" ":(_=0,"\n")),_/=2);} /*- Warp -*/

Obj2pov was created to support uv-mapping and conversion to
UV-Pov/Superpatch/Megapov's uv-aware mesh format (not mesh2). There are some
cases where the obj to 3DS conversion doesn't work properly (at least with
freeware tools) so obj2pov is still a viable option until someone comes up
with a 100% reliable obj to mesh2 converter.
