I created the characters for the Seance Character Demos, from initial sketches through final sculpts and implimentations. The characters were built for expressive VR performances using high-end facial and full-body motion capture (Faceware and OptiTrack), with performances by local theater actors. Two free demos are available on Steam.
We created character awareness systems that are layered on top of animations. Characters are aware of the player and are able to track them with their eyes and body.
