Dear Users,

The exquisitely detailed MetaHuman, capable of natural realistic motion, has had a big impact on the media and entertainment industry. On the other hand, bringing Metahumans to life while crossing the uncanny valley remains an immediate challenge to real-world production. iClone MetaHuman Live Link is the answer you’ve been looking for, with the ability to let Metahumans talk, emote, and act according to your wish. It provides designers a highly efficient way to apply facial and body animations, along with lip-syncing—all in one application!

Limitations and workarounds:

• Using CC3+ characters with ExPlus as the dummy characters is recommended.
• Limitations: 

• UE does not support negative values for facial expression sliders:

• Tongue motions will not be exact:

• “Mouth Close” works only when applying Jaw Open (Default & ExPlus profiles).

• The Look at function won’t work for face-only Live Link connection because there is no control over the head bone - the entire body will need to be Live Linked instead.
• Use the Face Key > Muscle Panel to properly drive the eyeball motions.
