During May 2025, Celine contributed to the QtenGrv/ProjetAlien repository by delivering two feature-level Unreal Engine asset integrations focused on enhancing visual fidelity for tutorials and materials. She expanded the material asset library with a new binary asset and updated the livretuto feature with several texture and visual assets, all managed through disciplined version control. Her work involved asset integration and game development, specifically handling Unreal Engine asset files without introducing code changes. This approach aligned with the project’s content pipeline, improving asset readiness for upcoming features and elevating the visual quality of in-game tutorials and book-related content.
