One of the fastest growing areas of creative expression in games has been the emotes and animations you can apply to your character in games like Fortnite. Yassine Tahi saw this realm of self-expression coming, and created a platform that democratizes the creation of character animations. With Kinetix, individual creators can capture movement and make their avatar animations available through a marketplace--and end-users can invoke them through text-to-animation generative prompting. This requires a huge number of challenging technology problems to be solved: motion capture with a normal camera that maps to the character rig; adjusting animation to the geometry and physics of an environment; labeling the data in a way that generative AI technology can make use of it; and then making animations interoperable across different games, virtual worlds and metaverse platforms. Some of the games and platforms we discuss include Zepeto, Inworld, The Sandbox Fortnite and NextDancer.
