CodeMiko

Who is CodeMiko?

CodeMiko is a 3D virtual streamer and online persona created by Youna Kang, who appears on Twitch and YouTube as both the character CodeMiko and the behind-the-scenes Technician. She is known for long-form interactive livestreams and interview-style segments that let viewers influence the avatar and environment in real time. citeturn0search12

CodeMiko Visual Style and Technology

The avatar is a hyper-realistic 3D model created in Autodesk Maya and textured with Adobe Substance, rendered in Unreal Engine. Live motion capture drives the model using an Xsens suit, Manus VR gloves, and a facial-tracking helmet that uses an iPhone depth camera to capture expressions. citeturn0search12

Kang and her team have also demonstrated real-time streaming and staged IRL-style demos using Unreal Engine 5 to showcase lighting, environments, and advanced interactivity for VTuber presentation. citeturn0search1

Persona and Narrative

In-universe, CodeMiko is presented as a video game character who never got a game and now wanders different worlds while breaking the fourth wall. The project includes a darker alter ego called Glitch, which appears with a different visual style and voice, and the Technician (Kang) occasionally appears as a separate on-stream persona. citeturn0search12

Interactivity is central: chat commands, donations, and on-stream triggers can change the avatar, spawn props, or alter scenes during live broadcasts. These interactive mechanics are used across Twitch streams and are also highlighted in YouTube clips and demo presentations. citeturn0search12turn0search1
