Hi, if the mecanim animtion system supports runtime change animationclip in unity4? for exsample, i have two animator states, StateA is normal animations, it has a blendtree that holds animationclips like idle, walk, run. and StateB has only one animationclip like attack(which in Motion or maybe in blendtree -- only one animation node), at runtime, i want to change the animation in StateB. i have search the whole scripts api, and find nothing(the interfaces are all read only). thanks very much.
