CGI Skin Realism Techniques

The video explores the evolution of CGI characters over two decades, focusing on the advancements in creating realistic skin. It highlights the journey from lifeless CGI skin in 'Final Fantasy: The Spirits Within' to the more believable skin of Alita in 'Alita: Battle Angel'. Key techniques such as albedo mapping, displacement maps, and subsurface scattering are discussed. The video also covers the impact of these advancements on the visual effects industry, including the use of subsurface scattering in movies like 'Shrek' and 'Harry Potter'.

What was a significant technical breakthrough in CGI character development over the past 20 years?

• The creation of animated backgrounds

• The development of realistic human CGI characters
