Anime Girl is designed to be used Preview Mode, as well as rendered. At least, that's what I assume, from the promos. The documentation isn't that great. The readme doesn't even have the usual list of files. Just instructions on how to use the developer rig to add her morphs to clothing.

I've played a little with Anime Girl, and it seems Superfly is a lot more finicky when it comes to lighting. And you can't really predict what it will look like when rendered, while Preview and Firefly are a lot more forgiving.
