I'm building a new 45degree character, who I want to be able to face either left or right. So I designed two hip sprites for either direction. But only the "Default" sprite will bend and warp with the character's movements. The secondary sprite just stays in place. 
It seems to be connected to the Hip bone, but not the Torso bone, so when the torso, head, or arms are moved, it won't go with them. But it seems connected correctly to the thigh bones. Could someone explain to me why the secondary sprite doesn't operate correctly, and how to fix it? Replacing the hip sprite seems like a useless feature if the replacement doesn't cooperate.
