I really, really love your edits! Thanks very much for providing such a nice collection of them.
I know what the waist gap problem is, and have a picture here to show you. When Blizzard released 3.2, they added a new pants model to the game, which is used on a lot of the t9+
armor. It's the kind of
pants that have extra padding on the sides. Unfortunately, I think your model edit for the lower half of the body only affects form-fitting leg armor. When a character wears the new pant model, they run into a problem:
I definitely still keep using the model, especially since my rp gear doesn't include the new model, but this is the "gap" that was mentioned.
