I feel like I am missing something with adding bone layers.
I have watched multiple times, but I don't see a section where you show how to add a new armature to a new layer. Every time I attempt to do this it always adds the armature to the first layer again. I am an animation noob, so I am sure it's something easy. I tried to google, but I am not having any luck.
I am talking about the transition at around 9:38
