There's 3D World, but that covers all 3D, not just Poser.

If you are looking for a good Poser related read, I'd recommend Denise Tyler's book called 'Practical Poser'. It's usually my first port of call, along with this forum, if I'm stuck.

My Poser 7 has been behaving erratically ever since I installed SR3; however, not everyone is having those same problems so I'm wondering if a Windows update at around the same time is the cause.
