Senior FX Artist & Pipeline TD based in Taipei, Taiwan 🇹🇼
Bridging hands-on visual effects production with studio pipeline architecture.

About

I have 15+ years of experience in feature-film visual effects and pipeline engineering.

My work spans hands-on Houdini FX production and pipeline architecture. I have led phased studio transitions to Houdini and Solaris, designed layer-based OpenUSD workflows, and developed C++ and Python tools supporting production workflows across Maya, Houdini, Solaris, and Nuke.


Tech Stack

Languages & APIs

Python VEX C++ Qt

DCC & Production Software

Featured Open Source Projects

Pipeline Architecture

  • openusd-pipeline-architecture
    OpenUSD · Solaris · Python · Asset Resolver
    Reference architecture for a production OpenUSD pipeline: 12 design documents on layer stacking and overrides, publish packaging, version pinning, validation, and Solaris implicit-layer governance, with tested Solaris output processors and USD splitting tools. Documentation in Traditional Chinese.

DCC & Rendering Plug-ins

  • maya-gaussian-splatting-viewport-plugin
    Maya · C++ · OpenGL · Viewport 2.0
    Maya Viewport 2.0 plug-in in C++ and OpenGL for real-time 3D Gaussian Splatting (.ply) rendering.

  • nuke-lens-distort-cv
    Nuke NDK · C++ · OpenCV
    Nuke NDK plug-in for lens distortion and undistortion using the OpenCV rational polynomial model (k1–k6, p1, p2) with Nerfstudio JSON support.

Procedural & Motion Tools

  • gnm-houdini
    Houdini HDA · Python · Google GNM
    Houdini Digital Asset (HDA) integrating Google's parametric statistical 3D head model (GNM) to generate editable head meshes in SOPs.

  • kimodo-houdini-bridge
    Houdini · Python · NVIDIA Kimodo
    Pipeline bridge connecting NVIDIA's text-driven motion generation model (Kimodo) directly into SideFX Houdini.

AI Agents & Studio Tooling

  • houdini-tools
    Python · CLI · MCP · OpenUSD
    Lightweight toolkit and MCP server for inspecting .bgeo.sc geometry caches and USD scenes without requiring a local Houdini installation.
