Bringing Characters to Life with Real-Time Facial & Body Animation



Bringing Characters to Life with Real-Time Facial & Body Animation
PROBLEM
Creating believable, real-time facial animation in VR presents unique challenges. In this high-stakes training scenario, the goal was to enhance character believability without adding latency or compromising performance. The project demanded more than just visual accuracy — it required emotional authenticity delivered in real-time, all while running on constrained VR hardware.
SOLUTION
To meet the demands of real-time interaction and emotional expression, we developed a hybrid workflow that combined pre-authored blendshapes with runtime animation logic. We worked closely with animators, developers, and instructional designers to refine both the technical rig and the in-headset feedback loop. Weekly playtests helped identify subtle issues that wouldn’t show up in flat screen previews.
Several innovations contributed to the final success of the system. These included both technical breakthroughs and usability improvements for artists and developers alike. By integrating runtime tools with Unity’s environment and focusing on scalable solutions, the system maintained flexibility without sacrificing fidelity.
AccuLips allowed us to sync lip movement with voiceover quickly, replacing time-intensive manual keyframing.
Facial expressions were recorded live via webcam, using mocap to capture nuanced emotional states across dozens of clips.
Each audio-driven animation was saved as an individual asset, giving us a modular library for rapid implementation in Unity.
The system was praised for making characters feel more human, responsive, and emotionally nuanced — even in fast-paced VR training scenarios. Internal stakeholders called it a “night and day” difference compared to the previous build. Most importantly, learners connected better with the narrative, improving training outcomes.
