BLENDING LIFE
Blender 3d Realistic & Stylized Human Challenge

Photo-realistic humans in movies like Beowulf, The Matrix and Animatrix (Jue vs Thaddeus) has stunned audiences worldwide, but the constant battle against the "Uncanny Valley" has left many an artist utterly frustrated. Yet every so often on forums like CGTalk and elsewhere, we see stunning images from seemingly genius artists, who are able to recreate digital human doubles so perfect that it boggles the mind. Welcome to the world of the lifelike CG created human.

During Blender's history we've seen very few photo-realistic humans even though our beloved application is more than capable. It's hard work and it takes a lot of patience, but lets show the CG world what we can do. And most importantly ... HAVE SOME FUN!
