Why it’s so hard to make CGI skin look real

Realistic-looking skin isn’t all that different from realistic-looking skim milk.

In the above video, Vox’s Phil Edwards looks at why realistic CGI skin is so hard for visual effects artists to master. Weta Digital’s Nick Epstein and Luxion’s Henrik Wann Jensen serve as guides to the parameters that separate realistic-looking skin from the waxy, fake-looking CGI of the past: albedo, displacements, subsurface scattering, and dynamic changes.

There’s been extraordinary progress from the cutting-edge CGI characters in 2001’s Final Fantasy: The Spirits Within to 2019’s Alita: Battle Angel. This video shows a bit about how that happened.

Jensen’s website has links to most of his key papers: graphics.ucsd.edu/~henrik/

Weta’s Alita site is here: www.wetafx.co.nz/films/filmog...

Skin it's also the most difficult thing to get natural results in movie colorization. Movie colorization could do a better job if they had more time and better budget, to separate the skin in more zones to get more color variances. Basically film colorization creates skin color by just sign a color for each tone of grayscale, something that it's not enough to get very natural results.

We have this innate ability to know the difference between fantasy and reality because The Almighty One gave us this power. Its why all these false flags were exposed. Its why its so hard to create realistic looking skin which can fool a God created being living on a God created world.

@TheReal Doge Maybe because it's still difficult to get closer to the real picture in detail, as the discovery of anti-aliasing techniques on text takes a long time. And I believe they are very intelligent people.

I think the big eye choice for Alita was a great decision for the sake of longevity. By more blatantly putting a gap between itself and realism, it allows the effects and any uncanny liberties to be less distracting. Then again, I've seen a lot of people react negatively to any "deformed" features, but they were probably gonna be SOL anyway.

Back in 2001, Spirits Within blew my mind. It was a huge technical achievement back in the day - it almost bankrupted Square. Of course 20 years leads to artistic and technical improvements, but I still believe that FF was a milestone.

Finally I found the reason why black skin used in video games always were better looking than white people. The answer is Black skin is reflective and its main feature is to bounce off light that why it look realistic while white skin were evolved to absorb light, while absorbing it bounces inside the skin. This is amazing, technology is just amazing.

"How could.. how could.. how could... " I don't know -- why don't you just talk about 'how it could...' instead of wasting time trying to build suspense? People read the title; they know what the video is about. They are watching the video to learn about the subject, not to listen to a sales pitch for watching the video.

I'm more interested in when both movements AND 3d graphics won't cause any sense of disconnection at all (animation isn't only about visual fidelity). Graphics wise, even with the biggest budget, it's still uncanny valley in my opinion (and I ask myself if things will ever change since nothing beats reality).

I hope the sequel for Alita gets greenlit. The moment I saw the trailer in 2019 I instantly got hype not knowing who she is or what's the story is about. The visuals pulled me in, the characters and story made me stay.
