Thanks ironbearxl, there's few bugs in my script. Skin's mirror tool works similar (select verts hit the mirror button), but is much more enhanced. I have tools that convert Physique to Skin and Skin to Physique, so I use them both.
Wow, you should return that book. Not only are they fricken idiots for even suggesting physique, they were completely wrong about both modifiers in their description. Both modifiers let you type in weights, which until Max 8 was one of the best methods for skinning game characters. It sounds like they're not even going to…
