I have made the autonomous body for my follower, but for some reason it is used only 100 weight meshes of body, hands and feet (malebody_1, malehands_1 and malefeet_1).
I have in folder all needed files (1st screenshot). But I've also made autonomous armor for him and armor meshes work as should.
Here are screenshots: https://imgur.com/a/0ikyuGr
As you can see, the body meshes doesn't change.
