Maybe you misunderstood me... they're doing just that, there's the least amount of human involvement and the thinest possible layer in this tech. They're basically showing you a new, separate digitized head of the actor for every frame. Doesn't get any better or closer than that, except it requires more resources.
It's like skinning and blendshapes and static textures are a form of lossy compression, and this approach is the lossless compression, so it'll waste some memory, but it will have better quality.
Also, on a PS4/X3 level system they'll be able to increase the texture resolution and add specularity and a better skin shader as well, so it'll look even better and the deformations will remain as lifelike as they are in here. It's forward looking tech just as much as Frostbite2 or Cryengine3 are, good enough on current hardware with potential to utilize upcoming consoles even better.
Didn't misunderstand u there, just saying that the tech is too heavy for the current gen hardware. The whole point is believable faces, but the shaders are being downgraded, lighting being downgraded and texture resolutions dropped , just to get the movements of the face across. But the face , on the whole, looks more fake than other techs out there. Yes, tiny movements have been captured, but I think its more a case of they haven't been able to get the tech streamlined/optimised enough to get desirable effect in a game. Maybe, because their tech churns up gigs of data for each second of performance, is more suited for animated films than games. They can make Beowolf 2 with it.
I feel it is being forced onto games, more than being suited for games. Atleast for the consoles. Why don't they rather make the game for PC, and let the potential show. Also, are they expecting that next gen consoles will have such a huge bandwidth for data that they will be able to capture full body performances? I don't think so, at least as of now when Nintendo is expected to churn out another "last gen" HW for the new Wii and Sony and MS supposedly pushing back their plane for next gen to 2014.
But then, there's the other point of view that even cartoons can evoke real emotions if the facial movements are correct while the faces are unrealistic. Look at all the animated films we have !!! So......
also, Heavy Rain had believable faces but awkward facial animations, especially the upper lips made the teeth show in a strange way when talking. Other than that, the tech worked pretty well.
I am not saying that they
should have realistic looking faces, but I thought the tech promised that first and foremost. Faces and performances that are a ditto of their real counterpart. I am not seeing that really.
The game , on the whole is very interesting though. But it still feels like an investigative GTA. I was expecting realistic humans.
