If you recall Zeratul's campaign with the preservers, Maar was the evil hybrid. Anyways he has an animation that plays on his birth or powerup or something like that, basically its energy surrounding him in a cyclinder. Any idea's how to play this at will?
I don't know, which animation you are referring to exactly, but if it is no animation of the actual model, it is probably one of the various complementary models. Have a look at the HybridWarpIn/Out, HybridProtossBlackDeath or HybridProtossFinalDeath models.
