From Tools to Terrain Immersion Is the Mission.

This page showcases my environment work built with 3ds Max, ZBrush, Substance, SpeedTree, and World Creator, and brought to life in Unity.

4-Day Art Test: A Fully Crafted Environment, Built from Scratch

This environment was built entirely from scratch, including modeling, texturing, lighting, and composition. Developed a custom shader for everything making it react to the weather setting, ensuring both artistic quality and technical efficiency."

Every Shader and Interaction is designed and implemented as a part of this project

VTW - Vingo

Senior Environment Artist / Technical Artist

Duration: 02.01 2021 ~ 02.01 2024

Created and optimized environment assets
- Created and optimized props, shaders, and vegetation with performance as a priority, utilizing SpeedTree and custom Unity shaders and many third party Unity Assets.
Built versatile master environment shaders
- Dramatically reduced shader variant count from thousands to just 22, enabling streamlined builds and faster iteration.
- Designed for broad material compatibility across platforms (mobile, PC), achieving high visual fidelity with minimal performance overhead..
Collaborated cross-functionally with engineering teams
- Debugged rendering issues, scene management, and optimization
Designed a flexible authoring environment with Procedural Pipeline
- Used Vegetation Studio Pro, Microverse, Unity Spline, Curvy Spline with Custom Automation Script to support migration of splines
- Supports live feedback and dynamic updates, reducing iteration time and empowering level designers.
Focused on scalability and optimization
- Ensuring assets and systems could support both small-scale and large-scale environments without loss of performance.

Feature Prototypes

I proactively develop feature prototypes to explore untapped gameplay potential, designing and testing mechanics that reflect my own sense of fun.

I believe discovering the ‘spark’ often comes from experimentation, and I continuously push for creative additions that enhance the overall player experience.
