Hi! I've been stuck on this part. I've added head and neck contols but when i grab or rotate the head or neck, shoulders also move with it. I've tried it alot but could not fix it.
The shoulders look like they are parented to one of the Neck bones. They should be parented to the Top Chest Tweak control ("Chest_02_tweak") That way if the chest deforms the shoulders will follow, but they won't be skewed with any stretching.
