This presentation will introduce to you a character animation system using machine learning, dubbed MotorNerve, which implements two core character animation functions: locomotion control and transition animation generation. First, by combining Motion Matching and Learned Motion Matching technologies, MotorNerve achieves high-quality, low-consumption locomotion control while speeding up the tuning process for Learned Motion Matching. Secondly, MotorNerve also implements an inhouse Motion In-Betweening (MIB) algorithm, which uses a variational autoencoder to encode leg movements, significantly improving the foot skating problem of existing methods. This method, a joint work by Zhejiang University and TiMi Studio Group, a Tencent Games studio, has been published in SIGGRAPH 2022. MotorNerve applies MIB to interactive animation scenarios, generating high-quality transition animations while saving the project costs.


You will gain a better understanding of the principles of Motion Matching and Learned Motion Matching technologies and their applications in locomotion control systems; at the same time, you will also learn how Motion In-Betweening technology can improve the quality of transition animations.

Intended Audience

The lecture content will be progressive, and practitioners or enthusiasts of animation technology or machine learning technology are welcome to participate.
