Was this at Ubisoft maybe? I remember their presentations, some really amazing tech a decade ago... Never seen anything as straightforward to use in off-the-shelf software since.
It wasn't, my friend certainly wasn't the first to do something similar, this was much more recent. I was just impressed by a demo he showed me of his work. He did procedural rigging for Darktide 40k, and physics based animations for The Finals. Unfortunately I don't think his software is available outside of the companies that hired him.
