Ryou Umekubo developed and refined a core 3D court scene for the Luca-Umekubo/Product-Design repository, focusing on visual fidelity, collision accuracy, and maintainability. Using GDScript and Godot’s 3D scene management tools, Ryou consolidated assets into a dedicated scene file, adjusted dimensions and border thickness for improved collision visuals, and set up lighting and camera angles to enhance realism. The work included proactive repository hygiene, such as removing unnecessary ignore rules and system files, which streamlined source control and reduced onboarding friction. This engineering effort enabled faster iteration on the Court project and established a cleaner, more scalable project structure.
