Hey! I'm Yohan Kang

I'm a software engineer based in Los Angeles, CA. I've worked on games, XR experiences, and generative AI tools.

You can take a look at my portfolio below or you can find my resume here.

Professional Projects

I previously worked at Playbook3D, a startup focused on XR and generative AI tools. I started out developing an XR design tool in Unity, and later transitioned to working on tools that integrated generative AI into 3D workflows.

XR Design Tool

Playbook Blender Add-on

PlaybookXR is a Unity-based tool for designing, prototyping, and refining XR interfaces directly in XR. While working on this project, I built many features like object selection and manipulation, multiplayer synchronization, augmented reality support, and animation keyframing.

Playbook Unity SDK

This custom Blender add-on integrates Playbook3D’s AI Render Engine, making it easy to generate AI-powered 3D renders. I developed this project mostly on my own, building functionality to capture renders through the scene camera and generate essential compositing passes (mask, normal, outline, and depth) before sending them to Playbook’s backend for processing. I also created a version control system that lets users update outdated versions of the plugin with a single click.

This Unity package allows users to generate AI-enhanced 3D renders from images captured in the Unity editor. I built the entire package from the ground up, developing a system that captures a series of in-game renders and applies custom fullscreen shaders to generate key image passes (mask, normal, outline, and depth). The processed images are then sent via WebSockets to Playbook’s backend for AI rendering.
