Why does my hit reaction blend out before it finishes?

AnimBP transition Duration defines the blend window. If the source animation is longer than Duration but the rule is true earlier, the engine starts blending out and the visible motion is clipped. Increase Duration or use Has Exit Time.

What is Bind Blend Out To Animation?

A property on the source state. Ties the start of the blend-out to the source clip's natural end. Useful for reaction animations that should always play to completion before transitioning.

How do I make a transition wait for the source to finish?

In the State, set Always Reset On Entry off, Bind Blend Out To Animation on. Or use a Notify near the source clip's end and gate the transition on receiving that Notify.

Fix: Unreal Anim State Machine Blend Out Cut Short

Quick answer: Increase the transition’s Duration, enable Bind Blend Out To Animation on the source state, or use a Notify near the source clip’s end to gate the transition. Animation plays through to completion.

A 1.2s hit reaction animation gets cut at 0.4s when the player resumes input. The transition rule fired the moment input was held, blending out the reaction.

The Symptom

Reaction or one-shot animation visibly clips. Smooth blend but starts too early. Often noticeable on hit reactions, dodges, or attack recovery.

The Fix

Bind Blend Out To Animation. On the source state (HitReaction state in the State Machine), set:

State Properties:
  Bind Blend Out To Animation:  true

The blend-out timer doesn’t start until the source animation has finished. Transitions wait their turn.

Or longer Duration. On the transition arrow, set Duration = (source clip remaining time at trigger). For a 1.2s clip with rule firing at 0.4s, Duration = 0.8s plus a small overlap.

Or Notify-driven transition. Add a Notify at the end of the source clip. The transition rule includes “Notify Received: HitReactionDone.” Until the notify fires, the rule is false.

Verifying

Trigger the reaction. Watch in Persona’s State Machine viewer with PIE running. State should stay active for the full clip duration before blending. If still clipped, inspect rule conditions and binding.

“Bind Blend Out. Or longer Duration. Or Notify gate. Animation plays out.”
