The new webcam face tracking and audio to face for Metahumans is great, but if you want it to work with your already set up custom characters with the standard ARKit 52 Shapes it won’t work out of the box. If you are using Morph Targets or Pose Assets with the 52 Shapes naming scheme you can just rename them to this new list and it should start working! Have fun and please show your results if this helps!
