We've been trying to learn that for years.What are the assets for the mother and daughter?
After many wasted hours searching for the assets, I reached the conclusion that when we find them, the giveaway will be the eyebrows.
Mother and daughter both have the same eyebrows and I've never seen those eyebrows on an asset.
I'm guessing G2, and probably from an offbrand site like renderosity rather than daz3d. But that's just a guess.
