The UVs are not perfectly symmetrical. That's a glitch. I didn't have the tools at my disposal to create symmetric UVs. The mesh, however, should be. I'm using the mirror function in Wings to make it so. If anyone finds an asymmetry in the original mesh, please tell me. It's a bug, and needs to be fixed.

The asymmetries that Poser creates I can't help with. pjz99 has been complaining about these for a long time, and apparently the good folks at Smith Micro are trying to fix it now. At the moment, the best solution I can see would be to use the original mesh from the geometries folder. For head morphs, it might be possible to export via DAZ Studio and load the morphs into Poser, but I haven't tried that yet - or use MorphLoader or MorphLoaderPro in DAZ, which is what I do.

General advice: don't trust anything Poser spits out. If you need to use Poser exports, check them very, very carefully. I'm serious. There are so many chances to mess things up it's not even funny anymore.
