Hi NtyCar,
As a troubleshooting step I replaced the “FallingLoop_RootMotion” animation with the “ThirdPersonJump_Loop” from the blank Third Person Template and the animation works as expected. That is, the character is no longer able to make a 180 turn in mid-air while. Also the character continues the forward momentum of the jump instead of stopping and launching straight up, as it did when I changed the order of the states in the state machine.
So the problem appears to lie with the “FallingLoop_RootMotion” animation instead of with your AnimGraph set up. Note that replacing the jump animation is a troubleshooting step and not the final solution. For instance, doing it this way causes the character to stop upon landing and restart running verses transitioning back to a run state upon landing.
