Core & Platform Engineering
Maintaining a massive Unreal Engine codebase through 5 major version upgrades (UE 5.1 to 5.6), ensuring stability for thousands of enterprise users.
- Mac Arm64 Migration: Spearheaded the packaging pipeline for native Apple Silicon support, unlocking a 20-30% performance increase over Rosetta.
- Rendering Pipeline Stability: Debugged complex shader regressions and skeletal mesh tangent recalculation bugs using RenderDoc and Unreal Insight.
- Automated Validation: Built comprehensive testing suites covering scene serialization, transform hierarchies, and complex Undo/Redo state management.
- Performance Investigations: Traced a shadow-rendering slowdown to the upstream engine change behind it, and investigated VRAM issues in heavy architectural scenes with Unreal Insights memory traces.
NoteCase Study: Scene Capture State Sync
Resolved a critical motion blur failure in high-resolution exports by architecting a custom frame sequence to manually trigger end-of-frame updates, ensuring the render thread had accurate state data before capture began.
Real-Time Telemetry & Monitoring
Architecting high-performance profiling tools for complex scene analysis.
Statistics Monitor Architecture
Architected and developed a real-time profiling tool providing deep telemetry for resource usage, enabling both internal teams and users to optimize heavy scenes.
- High-Performance Telemetry: Processed real-time data for scenes exceeding 1GB of texture size and millions of polygons.
- Asset replacement on-the-fly: Enabled deep dependency tracking, allowing users to replace textures or meshes directly from the monitor to resolve performance issues.
- Refined UX: Implemented high-performance UIs for memory and complexity tracking, significantly improving code readability and extensibility.
UI Systems & Interaction Architecture
Building scalable interfaces and complex interaction systems for enterprise-scale datasets.
Material System Architecture
Solved a critical UX bottleneck by migrating the legacy Material Panel to a virtualized Unreal TileView (C++, Slate).
- Drastic Performance Gain: Reduced load times for 5,000+ materials from 15 minutes down to ~0.5 seconds.
- Multi-drop Material Tool: Engineered a frontend/backend solution for rapid, batched material application across multiple scene objects.
- Robust Undo/Redo: Architected a reliable transaction system for material and folder management.
Content Migration Wizard
Engineered an interactive migration wizard in Slate/UMG displayed upon Twinmotion startup to guide users through transitioning downloaded library content, assets, and persistent configurations across different engine releases.
- Persistent Content Migration: Automatically locates and copies downloaded assets from previous installations into a shared, future-ready directory.
- Selective Version Transfer: Enabled users to select source content versions and inspect estimated transfer footprints before initiation.
Scene Configurations & Global Settings
Implemented the Global Settings architecture for scene configurations, enabling users to create presets encompassing camera translations, object visibility, and material states.
- Auto-Capture & Batch Export: Engineered automatic thumbnail capture for configurations and batched exports across multiple formats (Images, Videos, Panoramas).
- Trigger Presets: Streamlined transitions between environment, material, and visibility configurations using centralized triggers.
Physical Camera Simulation
Bridged the gap between real-world optics and digital visualization by engineering systems that mimic physical hardware behavior.
- Focus Hunting Effects: Developed the mathematical backend for realistic focus hunting behavior in cinematic cameras.
- Dynamic Camera Lag: Implemented adjustable camera smoothing for professional-grade real-time walkthroughs.
