Thanks, this seems to work perfectly. More code than I anticipated, but 
oh well. I'll have to see if I can modify the exporter to allow for it 
natively.

A new issue I'm finding is that all the uv_mapping textures seem to be 
mirrored in either u or v , so I'm having to go through and scale them 
with a bit of trial and error. I'm assuming this is the fault of the 
exporter not doing the right-handed coordinated (milkshape) to 
left-handed (povray) correctly.
I'm not holding my breath, but could there be a way of not needing to do 
this by hand, either through scaling the mesh or something? It seems 
that whichever direction is closest to being in-line with z (either u or 
v) needs to be mirrored for the texture to work correctly.
