In this episode of Tech Talks, Roblox founder & CEO David Baszucki sits down with Oren Jacob and Vincent Petrella to explore our latest innovations in avatar movement. Building a fully extensible system that enables fluid, physically-based motion for characters across all shapes, sizes, and proportions is one of our most complex engineering challenges yet, requiring a full evolution of our avatar movement stack. We break down the systems behind that effort and discuss how new animation tools on Roblox are laying the foundation for more expressive avatars and more ambitious gameplay experiences.
