Loosely based is the term I would use, Matching looks is pretty rough with the poser models that I use (v4's face doesn't react well when attempting to match someone up to a real life person). To do the renders, I have a "script" of 250+ poses that I did by hand for every move... lots of work. I have roughly 350+, but use 250 of the best, it takes about 4 days of rendering, 24 hrs a day to render a match, so I figure it was easier to package just 1 vs 1 simulators.
Open for suggestions for another one. Although at the time of posting this, I had 6 downloads, so maybe it's not necessarily something popular which I can understand.
