So here's the deal. It seems there's a bug in the way Poser sometimes handles normals. It doesn't always show up but it has been around awhile. We've recently discovered it thanks to a similar issue on the new figures. It's something we're working to resolve but it has been my experience that in many cases the issue is not with the model (though sometimes it is, which makes it harder to narrow down). So if you're seeing a black spot on your mesh in Poser but not in any other program, it may be a Poser error...or not. Which isn't really helpful, I know but I wanted to let you know our programmers are looking into it.
