In movies, it is fascinating to watch actors when they are not speaking. It is mostly when I connect with the characters on an emotional level, and the interaction becomes deep and meaningful. I’ve come to realize a diverse range of rich facial expressions is critical to make the interaction possible. I had to teach myself the rigging and scripting. My experience as an animator gives me clear ideas how to achieve unique and genuine character performance. I start building a facial system to find the best combination between art / technology and accuracy / flexibility. With a help of some of the experts, we developed the face system that creates robust and expressive facial rigging.
