Hmm 3D animation are far from being cheap and or a better alternative to a live commercial model, Not realistic but a good quality example would be Tangled.that was $49,059 per second with 68 animators And those are toons!!! Ok good quality but still....toons so I don't see any company which isn't in the 3D business doing that just to do it and end up with the same results they would get with a real person at a much cheaper cost.Runway and Fashion models are expensive normal commercial everyday looking people models not so much to justify the cost of going 3D. think they get around anywhere from 75 - 250 an hour.
