Believe it or not, I know nothing about deformers. I have heard you lot go on about them, but have never had the occasion to use them. I'm not sure if my Vicky 4 has deformers or not.

Sadly, most of my software learning has been "run & gun."

On my last rig I had Poser 7 loaded with all the legacy content. This rig I decided against that. I don't think I ever really used any of it last time. Some of it really could be useful, but I never did.
