It's being "sold" as a feature for game development and along with the other game development oriented features just doesn't seem to work (props exported lose all materials/textures for example). So I guess they repurposed it with the 2014 Game Dev edition and continued in that vein with Poser Pro 11 - albeit not very well. Very annoying to spend money on something for certain features only for those features to be useless for their intended purpose.
