I want to improve the animations in my game by using layered animations (such as those in this package). I'm using Mecanim animations. It seems pretty simple and self-explanatory to set up but I wanted to clarify one thing to make sure I'm doing this right: For the animations that are going to be layered on over the base animations, do they A) need to have their own Animation Types? And if so B) need to be called in sequence with the base animations? E.G. Say I have a 2 different base idle animations: Idle and Angry, that give the character a basic stance. And then I have 2 different animations on a second layer I want to be able to layer onto them: Shake Head and Nod. If I wanted to be able to do any combination of the base Idle/Angry and the Layered on Shake Head/Nod would I need an Animation Type for all four of them? and if so, would I then call them in an event by first calling the base animation and then the layered on animation?
