Okay, thanks.
I'll probably have the lo res version done tomorrow sometime. I'm not real sure what to do with it after that, how to transfer the UVs to the high res version. I don't know if UVL will do that or not. I've never tried such a thing before.
Although I do know I could simply subdivide it once in Lightwave and it would at least give the appearance of subdividing the UVs too, and any textures will remain intact.
I'm not sure that's the right way to go about it though...
