Is it possible to force the Animator to play an animation in a similar way to the legacy system? Timeline seems to be able to force arbitrary animation clips on an Animator component but I see no exposed way to do this from a script. The closes thing I found was to make a controller with a state for every clip you want to force and force the state to play.
I know the point of Mecanim is to build a robust FSM, pipe it a few parameters, and forget about it but sometimes you want full control.
