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.

Hey @Bejaymac, thank you VERY much, THAT REALLY HELPS!

I see now, it's not a question of better understanding Poser or D|S nor the UV-Mapper but how my modeling-software exports meshes. =)

I used the VERY! old Cinema4D CE+6 to make that thing and the .obj-exporter (at least of old/er C4D-versions) does some crazy things. It seems, that it not only inverts the Normals (they have always to be inverted before exporting the mesh so that they later show to the right direction), but also Y and/or Z axes of the object. So I just have to figure out how to "prepare" the mesh before exporting. (or model this kind of things from the start in Blender..;)

Thanks again!
