The UE4 LipSync Plugin takes the simplicity to the next level. The plugin is tightly integrated with the UE4 pipeline. If your character is setup correctly all you need is an audio file with the spoken text and a (optional) text file. Everything else is handled by the plugin.
The plugin is currently in an alpha stage and not available to the public yet. If you wish to participate in the beta test, please shoot us an email: info (at) cb-productions.de with the subject “Lipsync Plugin”.
