Meta's VR legs video wasn't what it seemed
 

When Meta announced that its Horizon Worlds avatars were getting legs in the near future, we got to see VR Mark Zuckerberg jump up and down to show them off. Apparently, though, what we saw wasn't a real demonstration of how Meta was able generate their full-body virtual reality avatars. According to UploadVR editor, Ian Hamilton, the event used animations that were created using motion capture:

For those who've been wondering about the legs shown in the Connect keynote (@hrafntho). Meta: "To enable this preview of what’s to come, the segment featured animations created from motion capture."

The process, which is called mocap for short, is widely used in cinema and games and entails recording the movements of a real person or object so they can be turned into computer animated graphics.
