Place The Reporter
Add Pose Overlay BlendStack Source inside the Motion Matching or BlendStack sample graph and connect the official BlendStack Input reference.
Use One Source Channel
Keep the reporter and the Stack on the same Source Channel. Use Default unless the AnimInstance has a deliberate multi-domain setup.
Test Clip Changes
Create Animation Overrides for a small number of known sources, then transition rapidly between bound and unbound Motion Matching clips.
Expected Behavior
- Bound dominant sample: matching Animation Override resolves.
- Unbound dominant sample: State or Context fallback remains.
- Near-equal Blend Space samples: hysteresis reduces source identity oscillation.
