Unfortunately, as you are aware, as she is sold, she is not rigged.
Why they would do that, well you would have to ask the vendor about it?
How much work there is in making her into a usable character, I don't honestly know.
You will have to wait for the input from someone knowledgeable in that area.
That said, I would put in my usual 500 points for her as a proper usable G8.1F character.
this is just a 3D scan, there's no easy way to make a G8/9 character out of her. means a lot of tedious manual work for days ... good luck to find someone who is willing to punish himself 😄
It's a 3D scan as already stated, they can be found at places like humano3d and other websites. The offerings usualy range from people working, running, fighting, nudes, and other various clothed and unclothed poses. All you do is import the usually flat scan into your scene and place it where you like. They can't be posed in any way.
He also offers the OBJ version which is a non rigged prop. Again these are HD scans converted and probably purchased from another vendor or scanned in his own studio.
From the vendors page. "Bring your wildest erotic female fantasies to life!" LOL! Anyone know who's wife it is? :p
