Smart bones and layer

[Doc986]

I created a character, front and lateral.
To run it from front to side, use the smart bone.
The problem is that when the character is on "front" the layer "arm left" should be up the body. When the charcter turn on lateral, the layer "arm left" should be under the body.
Create two layers and use the visibility is not good, because you can see the change of stroke (body's stroke).
What would be a way?

double click the bone layer go to depth sort and click enable animation layer order and when you start animation just move one layer above or below the other layer

or you can now use very small units in the layer z value controlled by the smart bone - just select 'order by depth'
