I've created an head that move by a bone. Next I've insert within the bone layer, a switch layer that contains 3 mounth of differnet size. But when I move the bone, the head move but the switch layer don't follow the movement of the bone. How can I do this, in order to make the character speak while...

I know that this question might be a bit stupid, but i cant find how can I increase the number of looped frames more than 72. Please help me.

You haven't understood me. I wont to place a layer BEHIND another layer.

I've created a layer for each part of my character body (left arm, right leg, head.....). When I join the layers in order to make the character entire, the left arm goes under the body. How can I raise that layer more than the body layer?
