SIGNA Training VR is a standalone train simulation experience on Quest 3, designed to create immersive, hands-on training scenarios for railway operators. Using a custom Sequencer-based tool, instructors can rapidly build interactive procedures involving levers, buttons, communication, and checklist systems. The simulation enables realistic situations too complex, rare, or costly to reproduce in real life, offering a scalable and efficient training environment

My Contributions

Tool Creation & Interactive Simulation System

Developed a custom scenario-building tool using Unreal Engine’s Sequencer, enabling instructors to design modular training sequences without coding.
Integrated event bindings to drive simulation logic in sync with the timeline: pause, resume, step control, and dynamic triggers.
Built a suite of interactable elements used across scenarios:
- Lever manipulation
- Button presses
- Phone/radio interactions with audio or dialogue
- Visual inspection zones for condition checking
- Horn activation and train movement triggers
- Step-by-step checklist system guiding the user in real time
Ensured all interactions were sequencer-aware, allowing precise timing and contextual feedback.
Designed the system as a reusable plugin, easily integrable into other Unreal-based projects, making the tool extensible beyond a single simulation.

VR Optimization & Technical Setup

Set up the project architecture in Unreal Engine with full support for Meta Quest 3 standalone deployment
Implemented custom rendering and performance settings:
- Mesh and material LODs
- Texture streaming optimization
- Mobile-friendly post-processing configuration
Carried out GPU and CPU profiling with Unreal Insights to identify bottlenecks
Refactored a costly outline system originally built with screen overlays, replacing it with a lightweight approach suitable for VR.
Structured the project around a plugin-oriented architecture, separating reusable tool logic from scene-specific content, ensuring modular deployment and scalability.
