My Character Is A-Posing

This is a common problem caused by Over-Sight, there are a couple of reasons why as I will explain below. For Live Retargeted Character's the System needs a Reference to your IK Retargeter which it will use to Retarget the Final Pose from the Mesh To your Character. Another reason would be that your character is not a Child of My Character (CBP_SandboxCharacter_DAO) If your character does not inherit from mine then you need to go into the Animation Blueprint and Change the Cast so that it is Casting and storing a reference to your Character and then fix any Compile Errors. If you duplicate the Animation Blueprint then you will need to duplicate all the choosers it uses and change their references to you new Animation Blueprint and then assign that chooser to your new Animation Blueprint. Direct References to the Character is required for Thread-Safe Operations to run on a Worker-Thread rather then the Game-Thread where everything else in the world is updated. Lastly if your character is not A-Posing but he isn't Animating either then it may be Optimization settings at fault. If your character is Following the UEFN Mesh, but it's set to 'Hidden in Game', then it's likely that your Visibility Based Anim Tick Option is set to 'Always Tick Pose', with this setting, the Bones will not be updated when he is 'Hidden in Game'. You will need to set this to 'Always Tick Pose and Refresh Bones' in order to fix this issue so that he will animate and your Character can Mirror his Poses.
