Hi. I think it would be very cool to have SmartBody integrated into Unreal Engine 4. It does a lot of amazing things. You could even become a hero of your own videogame, to translate yourself there as a rigged character automaticly.
SmartBody is a character animation platform originally developed at the USC
Institute for Creative Technologies. SmartBody provides locomotion, steering, object manipulation, lip syncing, gazing, nonverbal behavior and retargeting in real time.
SmartBody is written in C++ and can be incorporated into most game and simulation engines. SmartBody is a Behavioral Markup Language (BML) realization engine that transforms BML behavior descriptions into realtime animations. SmartBody runs on Windows, Linux, OSx as well as the iPhone and Android devices.
