there's no telling what is actually real time and what is "baked".
Artistically, this demo is wonderful!
Technically, it's somewhere between "yawn" and game-changing, depending on how much of the lighting and animation is pre-baked. Are the deformations of her skin, clothing, the water, etc. being calculated in real time, or was all the hard stuff precalculated and baked in?
Reason why this matters is because the more dynamic this is, the closer we are to creating actual emergent/interactive experiences with this kind of technology, rather than just a way to render static cutscenes better.
