I was just doing a test with mirroring and reversing just wanted the character to change direction after a random number of steps playing the mirrored and reversed anim with event(feet)sync.the blending in this scenario is quite strange(it really doesn’t swap to reverse up to a certain hi value) , but the strangest part is the root motion that doesn’t follow the anim during blending, but overshoot near 0.5 making the character quickly translate away.
The same blending without sync is totally ok even if it is not correct when using mirroring.
The issue is the same using state machine transitions and blending manually.
