ROFL, just found out this is a freebie and after having a quick look at it you can ignore most of my last post, the part about "clueless" is spot on though. Newbies I tend to point out where they went wrong and how to correct it, Pro's or people who should know better tend to get it in the neck from me, which is why I keep getting in trouble over at DAZ.

fuLLm00n1 is a double sided disc, it loads in face down, X rotate 90 will show the back of the disc and an upside down UV, X rotate -90 will show the front with a right way up UV, going by your textures at any rate.

fuLLm00n1_nbf is half a double sided disc, problem is you removed the wrong side, you removed the front instead of the back, X rotate 90 and in DS setting vertical tiles to -1, can't remember if it's U scale or V scale in Poser that's vertical but setting the right one to -1 will fix it.

So no need for custom UV's, just a better understanding of how things work in DS and/or Poser.
