Still frustigated.

On a suggestion from reddit, I tried using texture bake in Blender. That has it's uses, but this isn't one of them. It basically just bakes the uv-mapped texture onto another identical uv-mapped image. Useful, if you're trying to speed up procedural noise or add shading from a complex model onto a low-poly version; not so hot if you're trying to repro the texture image.

Back to povray.

Turns out Wings3D has a direct povray exporter. This seems to export the geometry successfully, and at least the code, to my highly inexpert eye, seems to include fun things like uv-mapping vectors and indices. It just doesn't seem to successfully export the uv-mapped textures. I haven't found a workaround yet that actually works. Crud.

I've just downloaded a java obj2pov app from github(that was a nightmare). I'll give that a try. Hopefully it will export a working uv-map.

Barring that, I'm hoping for some povray advice or possibly another tack.

Thanks TTYL
