“allowed users to upload a 2D photo and automatically create a realistic 3D avatar.”
“integrations to build out personalized avatar stickers” *** this little comment suggests creation of expressions without live feed
“live avatars that could be used during video calls”
To take from one base image and manipulating it into standard expressions and rendering in 3D will allow live facial emotes. Conceivably, upload a face and you could have access to a whole suite of emotes.
How much freedom is given to developers is the only question. It is all feasible tech and having a leg up with the acquisition will let them roll out much sooner. Seems like a good follow up for the Rthro release for realism capability.
