I figured it out thanks to dewshine's tutorial. ^_^ I was forgetting to delete the property set for the unwanted ages so they kept getting textures of 1's and 0's.
And I figured out how to properly family the hairstyles on datgen, but I don't think I am going to bother going back and doing it on all my custom hair. It would take to long.
Now I just have to wait for MTS2 to approve it!
