Worked on enhancing the Road Network editing user experience for the Synesthesias/PLATEAU-SDK-for-Unity repository, focusing on UI improvements that enable higher-precision input for generation parameters and introduce spline editing controls for roads and intersections. Leveraged skills in UI Development, Unity Editor Scripting, and USS to implement and finalize these changes, streamlining the editing workflow for Unity developers. Utilized UXML and XML to refine input forms and related UI elements, ensuring a more intuitive and efficient interface. The work addressed the need for more precise and flexible road network editing, contributing a single, well-scoped feature during the development period.
