Hiroyuki Seshita: the man who proved CGI is not the enemy of soul in anime

Published on May 08, 2026 | Translated from Spanish

When CGI in anime was seen as a visual heresy, Hiroyuki Seshita came to silence the critics. This director is the face of Polygon Pictures and a pioneer in proving that 3D can have soul and its own style. His commitment to a cyber-traditional aesthetic, blending digital precision with textures that evoke hand-drawn art, has redefined dark science fiction in Japanese animation.

The technical recipe for making 3D not look like space putty 🛠️

Seshita doesn't just model on a computer and hit render. His team at Polygon Pictures applies a layer of artisanal texturing that mimics the inking and shaky lines of 2D, making the mechs of Knights of Sidonia or the environments of Blame! feel raw. Lighting plays a key role: they use directional light sources and hard shadows to avoid plastic shine. Additionally, animation is run at 12 frames per second in certain scenes, emulating the rhythm of traditional anime.

When your favorite character looks like wax and you still love them 🤖

Of course, not everything is perfect. Sometimes the characters look like mannequins from a space department store, and facial movements resemble a robot with arthritis. But Seshita has an ace up his sleeve: stories so dense that you forget you're watching plastic figures. In Ajin, the demi-humans are nearly invincible, but their expressions seem straight out of a Blender tutorial. Still, the viewer stays glued to the couch, wondering if CGI has a soul or if it's just been sold to us really well.
