I agree with everything said above. This is the same issue texture painting software runs into, but since we're tricking Poser into a texture painting role here, the usual affordances for working around the problem are not readily available.

Here's another test render with the HyperReal texture, this time after extending the texture, as DCArt puts it, in Gimp with the help of the erode function. So that's the postwork option I mentioned above, as opposed to the option of tweaking the conversion object produced by my script with the method so beautifully explained by FVerbaas.

Honestly, since I don't have that many textures lying around that I might want to convert to a different UV mapping, I'm quite happy with that solution for my personal use. Happy to do a bit of extra work though if anyone is keen on using this method in anger.

The script is on my github (same username as here) under the pydeltamesh repository just in case someone's curious. It's got the snappy name makeTextureTransferObject.py. :grin: Hit me up for the details on the process if you think it might be useful to you.
