Lip Sync Work-flow in UE4
I have put together 3 videos which highlight 3 methods of lip sync using the workflow project I created. You can lip sync audio manually using papagayo or automatically using pocketsphinx or rhubarb. Further you can modify the lip sync data using the sequencer to edit the face key frames. Link to Repository: https://github.com/studiostry/UE4MBLabCharacterStudy
