Tentacle Sync https://github.com/EpicGames/FaceLink/tree/swift-rewrite Tentacle Sync is a bluetooth-based hardware device that enables an iPhone to receive timecode from a master clock on stage (i.e. the same hardware that drives other devices such as cameras). This enables the iPhone facial capture streams to be synchronized with the same timecode as all other devices on stage based on the master clock and thus remain aligned. https://drive.google.com/file/d/1G1NTqkBk9uKL2XXs9L6fqZsEtY5aswnM/view Licensees Git P4 /Engine/Source/ThirdParty/Licenses
