Well, you can use pretty much any figure you want. So your not limited to the very few poser figures. So that kind of blows the poser face room out of the water. Besides not being limited to poser. In fact. you don't even have to open poser to use it.

The texture that is generated need to be run through a paint program to get it cleaned up  a bit and the mirror morph is still lame. but over all, it works well.
 
If you practice with FS you get good at too. It's a tool and it does what it is designed to do.

Isn't there a demo to try and make up your own mind? It's like any software. Some some will hate it, some will gush over it and some like me think of it as another tool that gets you to where you want to go. So if there is a demo,try it and put more tha a couple of minutes into testing it before you decide if it is something you can use.
