The web page and readme state:-

"Cynthia loads into your scene and renders faster than most Poser figures.

If you're working on that huge project with a short deadline and need a Poser figure that wouldn't take hours to render, then Cynthia 1.0 is your choice!

Here are the items you get with your purchase of Cynthia 1.0:

    - Cynthia 1.0 figure
    - associated High-Res (4096 x 4096) textures files
    - associated geometry mesh

"

The free version comes with only 4 body textures each sized at 2048 x 2048 and one head parts texture sized at 1024 x 1024. No bump, no diffuse, no bells and whistles, just a basic set of low resolution maps. Enough so that you can preview the figure.

So the artist burned in some highlights into the low resolution preview, big whoop.

I feel that this figure has potential. I will certainly be looking into using it in more detail.
